I want to register for Covid-19 vaccination, how should I contact? In case I am not on the priority list for free injections but need to get vaccinated soon, can I get the injection service and pay myself? (45 year old reader in Ward 10, Go Vap District, Ho Chi Minh City)
When registering, we need to register on the national vaccination information portal, address tiemchungocovid19.gov.vn. You can register as an individual or as a group. Current wards and communes send information to record people's registration. As of now, we have not applied the service. For now, the vaccine is completely free. According to the schedule arranged for each ward and commune, we will vaccinate.
We do not choose the type of vaccine to vaccinate. The vaccines arriving in Vietnam are all highly effective in protection. Choosing this vaccine or that vaccine does not lead to difficulties in vaccine distribution.

My father is over 65 years old. If I want to register for vaccination, where can I register and can I choose the type of vaccine to receive? (Trinh Hoang Phuong Vu, 46 years old, Ward 12, District 11, HCMC)
We can directly operate the vaccine portal or download health records to register or register for household registration. And we don't have a choice because there is only one type of vaccine at each vaccination session to avoid confusion.

My wife is pregnant, can she get the Covid-19 vaccine? If yes, at what month of pregnancy is it best to get the injection? (Nguyen Van Cho, 31 years old, Chau Thanh, An Giang)
Pregnant women are one of the high-risk groups. If infected with Covid-19, the illness can be severe and affect the fetus. Therefore, the World Health Organization (WHO) has classified pregnant women as high risk and are given priority for vaccination. However, this prioritization is only implemented in high-risk areas. In low-risk areas, these vaccines do not have much clinical data related to pregnant and lactating women, so they are still deployed at a cautious level. There are no specific studies on which stage of pregnancy is best to inject. People in epidemic areas or in contact with people with Covid-19
9:06 am
Can foreigners permanently residing in Vietnam be vaccinated? (Tu Nguyen, 30 years old, District 7, Ho Chi Minh City)
Foreigners in Vietnam are also considered citizens in Vietnam, and are paid attention and paid attention by the Government. However, the registration software does not have a foreign language, so when registering, you must register in Vietnamese and if you enter your passport, there may be an error. In principle, we do not restrict injections and foreigners should register by organization for more convenience. In addition, foreigners in Vietnam can access the vaccine through the Embassy channel.
9:08
I am breastfeeding, should I get vaccinated or not? Will vaccination have any effect on my baby? So among the currently available Covid-19 vaccines, which ones are suitable for breastfeeding mothers, and should mothers stop breastfeeding after getting vaccinated? (Le Thi Thu Hong, 31 years old, District 11, Ho Chi Minh City)
Currently, it is found that vaccines in mRNA form, including Moderna and Pfizer, when injected into pregnant women, can have immunity and eliminate immunity through milk. However, whether maternal immunity has any effect or influence on children has not been specifically evaluated, because assessment is very difficult and symptoms in children are vague. Therefore, it is said that vaccines should be used for breastfeeding mothers. However, there is no data on the timing of protection and the vaccine's effect on the baby. So there are no instructions yet.
We recommend that the vaccination should not be given to pregnant and lactating women, because these are subjects of caution. But in the context of epidemic areas, vaccination is recommended, because these two subjects are at high risk. The mRNA vaccines have partial clinical data showing that they can be injected.
The J&J vaccine has not been specifically evaluated for breastfeeding women, but the technology is not too new and has been applied to the Ebobla vaccine. But clinical data is not enough to make a recommendation.
9:12 am
From what age can children be vaccinated with Covid-19 vaccine? (If any), what vaccines can be given to children, and when will Vietnamese children be vaccinated? What are the recommendations when vaccinating children? (Tran Phuong Linh, 31 years old, Cam Khe, Phu Tho)
Currently, only the Pfizer vaccine has had clinical trials in people aged 12 to 18 years old. The company also tested the group under 12 years old. In the US, this vaccine is required to add subjects for clinical trials before the US FDA approves it for younger children. However, the vaccine is safe enough to be given to children. In Vietnam, there is currently no Covid-19 vaccine for children because the number of vaccines we have is limited and we need to target people at higher risk. In addition, children infected with Covid-19 often have much milder symptoms and complications than infected adults. The rate of pediatric patients with Covid-19 becoming seriously ill and dying in our country is unknown. The first vaccine needs to target the object that needs protection. The Vietnamese government has negotiated to have 20 million doses of Covid-19 vaccine for children. Then we will vaccinate children, to protect the community.

Can doctors clearly say which subjects should delay vaccination, which subjects should not be vaccinated, and which subjects must be careful when vaccinating?
Which people are considered to have impaired immune response? Are there specific indicators?
What is a person with a serious underlying illness? What is heavy?
Regarding allergies, many people do not know whether they are allergic to any allergens or not, and they want to get tested for allergies before getting vaccinated. So, does the vaccination facility support allergy testing, or where do I go to get tested?
(Nguyen Anh Toan, 56 years old, Ha Nam)
Actually, if fully presented, the Ministry of Health has issued decision 2995 to classify vaccination subjects. The most important criterion for not being vaccinated is that people have grade 2 anaphylaxis or higher, to any agent. As for those in the delayed group, they cannot be vaccinated during this period. They have acute illnesses such as high fever, infection, high dose corticosteroid use, radiotherapy... those people must delay until the acute signs pass before they can be vaccinated.
People with mild allergies, not to the extent of anaphylaxis, cases with underlying medical conditions, pregnancy, breastfeeding, can be classified into the delay and caution group. These cases need to be taken to the hospital for injection and monitored closely and carefully.
Grade 2 anaphylaxis includes signs of skin allergy such as thick hives all over the body and is accompanied by facial edema, difficulty speaking, wheezing (due to laryngeal edema), difficulty breathing, increased difficulty breathing, and other unusual symptoms such as abdominal pain. People with all of these signs are classified as grade 2 anaphylaxis. And for grade 2 anaphylaxis, with two or more groups of symptoms, in addition to skin symptoms, other symptoms will contraindicate Covid-19 vaccination.
9:18 am
Regarding allergies, many people do not know whether they are allergic to any allergens or not, and they want to get tested for allergies before getting vaccinated. So, does the vaccination facility support allergy testing, or where do I go to get tested?
In vaccination in general and Covid-19 vaccine in particular, the Ministry of Health of Vietnam, WHO, the American Immunization Association and many health agencies around the world do not recommend allergen testing with vaccination and even Covid-19 vaccine.
When vaccinating, we often take history, like the person giving the injection will tell us about situations they have encountered. From there, the doctor will evaluate whether to inject or not. Because standard allergen testing must rely on the ingredients of the vaccine and takes a lot of time. Not to mention, allergen testing does not confirm whether the injector will have a reaction to the vaccine or not. And if there is a reaction during the test, it does not prove that the actual injection will definitely cause a reaction.
In particular, the allergen test will be injected intradermally (not in accordance with the manufacturer's indication for intramuscular injection). Therefore, when testing for allergens injected under the skin is done incorrectly, without the manufacturer's permission, when a reaction or anaphylactic reaction occurs, it is the fault of the vaccination organization.
In short, do not use allergen testing to test vaccine allergy.
9:24 am
At what facilities is the vaccine deployed? How to ensure that there are no large gatherings during pre-injection screening and 60-minute post-injection monitoring? (Nguyen Kim Ngan, email: kimnvt@gmail.com)
This is extremely important. We remember that Covid-19 vaccination occurs during the Covid-19 epidemic, so provinces with epidemics will prioritize the allocation of more vaccines. Thus, vaccination in epidemic areas will be more risky.
The vaccination program recommends spacing at vaccination sites such as organizing vaccinations in communes and wards, using large halls. The distance between injectors needs to be 2m and properly coordinated to avoid congestion.
When registering, people need to fill in all the information required by the system. When arriving at the injection site, the injector does not need to declare anything else. When arriving at the injection site, the doctor only needs to ask a few more questions, measure blood pressure, temperature, heart rate, and screen for health status. From there, the doctor will decide whether you are eligible for the injection or not.
The best way is to prepare everything before going to the injection site. When going in for injection, you need to ensure distance and make sure no one talks to anyone else. This is a way to avoid congestion and crowding.
9:25 am
The first shot I received was the AstraZeneca vaccine. When registering for the second shot, the hospital informed me that the AstraZeneca vaccine was out of stock, only the Pfizer vaccine was available. I would like to ask, what is the effectiveness of mixing two doses of vaccine to create immunity and prevent Covid, and does it create a stronger reaction after injection?
What were those reactions like?
(Pham Phuong Chi, 31 years old, Hiep Hoa, Bac Giang)
As far as we know, there are only clinical trials involving the combination of Astra Zeneca and Pfizer, of which Pfizer is the second shot. But this clinical trial was small, a few hundred people, so the evaluation information is difficult to conclude as representative of a large population. There is also an immune effect after mixed vaccination compared to 2 identical vaccines. That is why the Vietnamese Ministry of Health allows vaccination, but must ask permission from the person being vaccinated and must have an assessment and report before doing so widely.
After injecting Pfizer with the second dose, people reported more side effects than after injecting the same type, but it was not statistically significant.
9:26 am
First of all, can experts tell us what to note before and after Covid-19 vaccination in general? (Thao Nhi, 35 years old in Hanoi)
We remember one thing, we must have a comfortable mind before injecting. A comfortable state of mind, rest and adequate sleep will help build good immunity and reduce abnormal symptoms, including severe symptoms. The psychological cause we see a lot in the first round of vaccination, a lot of people react, while still receiving the same vaccine, in the next round it completely decreases. Therefore, psychological preparation before getting vaccinated is very important. You can wait until you are less worried before getting vaccinated.
And prepare enough documents to declare quickly, declare full information to receive thorough advice, avoid hiding information and leaving risks later. Everyone will be given instructions for post-injection monitoring. Everyone can go home after 30 minutes, continue to monitor for 7-30 days, especially closely monitor in the first 3 days. Everyone needs to monitor themselves carefully, notify the health care provider for help, and record and evaluate their case. Remember, do not self-medicate, you should notify your doctor.
9:27 am
Yesterday my friend got the 2nd Pfizer shot after the 1st AstraZeneca shot. He had swelling and pain in his arm for many hours but no fever. Is no fever because the vaccine is ineffective? (Huynh Phuong Thao, 45 years old, Can Tho City)
This can be seen in many people when receiving the second dose of vaccine. Normally, with the first dose, 50 to 60% of people have a fever and 20% have a fever with the second dose. This proves that the body is used to the vaccine and the vaccine is more specific, but it does not mean that without fever, there is no immunity.
Even if you don't have a fever, the second shot will still produce good results. This result has been tested and the Institute of Hygiene and Epidemiology has researched this issue so we can be completely assured.
9:30 am
Vietnam is currently importing many types of Covid-19 vaccines such as: AstraZeneca, Pfizer, Moderna, Johnson & Johnson... When injecting mixed vaccines, are there regulations on which two types of vaccines can be mixed together and which two types cannot be mixed together, doctor? (Nguyen Tuan Anh, 29 years old, Dong Da, Hanoi)
Currently, only AstraZeneca and Pfizer are allowed by the Ministry of Health to be vaccinated in combination with the condition that if the AstraZeneca vaccine is in short supply, Pfizer can be used instead, but it is not recommended to inject Pfizer every second shot. For now, it is still recommended to use two doses of the same vaccine.
9:30 am
What is the difference between the effectiveness of mixing and injecting 2 shots of the same type of vaccine? Are the antibodies obtained after vaccination higher than with the second injection of the same type?
Tested on a small group, not yet large, with a few hundred people, the immunity achieved with combined injections is higher than with single injections. This has been seen in the Ebola vaccine, people can extrapolate that it can be mixed injection. However, further proof is needed, more evidence is needed. We should not rely only on a few small studies to draw conclusions for all vaccines.
9:32 am
I know that there are many cases of people still infected with Covid-19 after receiving the vaccine. So, if I have been vaccinated with AstraZeneca vaccine and still get infected, can I continue to receive another brand's vaccine?
There is no vaccine that provides absolute protection against infection. Even with the Pfizer and Moderna vaccines, breakthrough infections still occur. The US healthcare system has recorded this phenomenon. People who have received two doses of vaccine are infected with Covid-19. In Vietnam there have been a number of similar cases. However, there is a difference in people who have been vaccinated but are still infected. They have no symptoms and serious disease complications. These people have very mild symptoms, or even no symptoms at all, and recover very quickly. That is the core value of vaccines.
If you are unlucky enough to get Covid-19, you need to keep a distance of 6 months after recovering from the disease before getting the next vaccine shot. This is very important because if you only get Covid-19 without vaccination, the antibodies produced after infection will not be too high. Even in some cases, after recovering from Covid-19, antibodies were not detectable. We still recommend vaccination 6 months after illness.
9:33 am
I have received two full injections of the Astrazeneca vaccine. If I want to get another vaccine of better quality in the future, is that okay? (Nguyen Dang Nhan, 37 years old, Tan Phu, Ho Chi Minh City)
The Astrazeneca vaccine itself is recommended to be given a third dose after 6 months or 9 months, and other companies such as Moderna also have similar recommendations. But it's all just recommendations, not specific instructions. In the future, if you want to get another vaccine, you can still wait for instructions from the Ministry of Health to get the right vaccine.

I have received the first injection of Astrazeneca vaccine - Japan. I had quite a few reactions after the injection: high fever over 39 degrees, difficulty breathing, dizziness, lightheadedness, sneezing, weakness, chills, and diarrhea. Should I continue with Pfizer or Astrazeneca for the second shot? Thank you doctor. (Nguyen Lieu, 41 years old in Van Lam, Hung Yen)
Quite a lot of people have this condition when getting the first injection, especially people under 45 years old, the normal reaction rate is higher than that of older people. However, according to our observations, people who received the second dose, including those with high fever and discomfort in the first dose, received the second dose very well. Therefore, we should continue to inject Astrazeneca at the second dose without worrying about switching to another type.
9:35 am
I got the 1st shot with the Moderna vaccine and am waiting 4 weeks to get the 2nd shot. In case the 2nd shot is due and I don't have Moderna, is there anything else I can get? Or what would it be like without Moderna? (Pham Manh Thang, 62 years old in My Dinh, Nam Tu Liem, Hanoi)
Currently, our vaccination team has a plan to keep half of the Moderna vaccine for the second dose. So you can rest assured that you will get a second shot. You don't need to worry that on the day of your vaccination, there won't be a second shot.
9:39 am
I was injected with the AstraZeneca vaccine. About 2 days after the injection, many tiny red spots appeared, at first only on my arms, then on my legs, then all over my body, but it only caused itching. About 7 days after the injection, it completely disappeared. I have read that post-injection reactions are due to drug allergy. So is my case serious? Will there be any effects if I receive the second dose of the vaccine, doctor? Thank you! (Nguyen Thi Thanh Thao, 34 years old, in Tan Hoa, Vinh Long)
We have recorded a number of such cases. The whole country has cases like this. This is just an allergic condition, classified as a common reaction, encountered in other vaccines we are injecting. In the second dose, people who experienced similar symptoms were very few. These people can still receive a second dose of the same vaccine but in the hospital. When injecting, at most there will be tiny red dots that will go away after a few days.
9:40 am
More specifically, a question sent in by many readers: Doctor, what are the symptoms that require immediate hospitalization after vaccination? (Le Thi Cam Tu, 24 years old, email: tulee.9898@gmail.com)
First, when you feel worried or unusual without explanation, you need to go to the hospital immediately. This is the first thing that comes to mind before there are obvious signs. More specifically, swelling, abdominal pain, and rapid heart rate are early signs of anaphylaxis that require medical attention for treatment, or high fever but fever-reducing medication does not reduce it, or high fever again after a short period of time is also a dangerous case that needs monitoring. In addition, we have distributed health monitoring sheets at home. If you have symptoms as recommended, immediately call a medical facility for assistance.
9:43
I received the AstraZeneca vaccine. After receiving the injection, I had symptoms of fever, sometimes hot, sometimes cold, temperature 38.6 and my whole body aching. After a day, the symptoms first changed to a state of shortness of breath and shaking limbs. So do I need to go to the hospital? (Tran Manh Ha, 40 years old, Vinh City, Nghe An)
Here we see that in these cases there is only fever, normal reactions, shortness of breath, trembling limbs are rare, but still limited to normal reaction monitoring. These people need to take fever-reducing and pain-relieving drugs. Whether we need to go to the hospital or not with signs of shortness of breath and shaking limbs, we don't have to go to the hospital yet. However, if there are other signs, such as pale skin or difficulty breathing, we ask you to immediately go to the hospital for assistance.
9:43 am
Expert, please tell me after vaccination, how should I eat, rest, and monitor to ensure safety and best for myself? By the way, the doctor asked if there are currently instructions on post-injection monitoring at home given to all people who get vaccinated? (Thai Doan, 43 years old, Bac Tan Uyen, Binh Duong)
We exercise lightly, do not play football. In fact, after getting vaccinated and playing football, there have been many unfortunate cases. Limit vigorous exercise, even for healthy people who are confident in their health. Be sure to rest properly, don't lie down all day, and eat well. Don't skip meals because of discomfort and loss of appetite, eat enough nutrients, drink enough water to limit fever and quickly overcome the problem you are having. You should eat fruits and take vitamin supplements.
In addition, you can self-monitor after injection at home through the instruction sheet that we send to the injection sites to the health sector or get it from the internet, to self-assess your health and when to contact a doctor for treatment if there are any unusual symptoms.
9:43 am
I want to ask if I can use other drugs after vaccination, and if so, how long after vaccination can I use them (Nguyen Van Hoang, 41 years old, Ho Chi Minh City)
Here I try to imagine that you want to ask about using drugs other than vaccines. If that person has an underlying disease, for example hepatitis, they must use hepatitis medicine; if they have H, they must use ARV medicine. We will continue to use this medicine. If we don't worry about getting vaccinated, we will have to stop taking the medicine.
9:46 am
Currently, my company has a number of employees who received the first injection 7-8 weeks ago, but have not received the second injection. So will this affect or reduce the effectiveness of the vaccine? (Hien, 42 years old, Phu Nhuan, Ho Chi Minh City)
Actually, the vaccine can be injected 4 weeks apart, but is most effective after 8 to 12 weeks. Injecting for 12 weeks or more is very effective. If you have not been vaccinated in 8 weeks, you can wait longer. If stretched over a 12-week interval, it is most effective. This does not only apply to the AstraZeneca vaccine, with the Pfizer vaccine, if it is extended by 12 weeks, the effectiveness is still higher.
9:48
I read the instructions and found that people with allergies should not get vaccinated. Please let me know if I have an allergic reaction to eating foods like shrimp and crab, can I get vaccinated? What should you pay attention to when injecting? (Nguyen Hong Ha, 40 years old, Dong Da, Hanoi
Actually, Covid-19 vaccine is contraindicated in cases of anaphylaxis and allergies, which can be considered, cautious and injected at the hospital for better handling. If you are allergic to shrimp, crab or fish, it is not included in the vaccine, so don't worry too much. There are many people who are allergic to weather, shellfish, fish or some other types of allergies. I recommend getting vaccinated early and most of the time there are no unusual cases.
9:50 am
I just got another vaccine, specifically the pre-pregnancy vaccine. Medical staff advise that you should wait at least 15 days to receive the Covid-19 vaccine. So if I get the Covid-19n vaccine 15 days earlier, will there be any effects? (Nguyen Phuong Thao, 27 years old, Hoang Mai, Hanoi)
Here I see that women who are pregnant or about to become pregnant need to be vaccinated. But there has been no research on combining vaccines with Covid-19 vaccines. Therefore, experts recommend that people wait 14 days from the last dose of Covid-19 vaccine before getting another vaccine.
9:52 am
Hello Doctor! Let me ask about the case where I was vaccinated with the AstraZeneca vaccine on July 5, but from July 28, I started having tightness in my chest along with pain in my shoulders and neck but there were no signs of cough or shortness of breath. I took two quick tests and both were negative. Doctor, can you advise me on whether the above symptoms are side effects due to vaccination? and how to handle it? Thank you Doctor! (Nhat Khoa, 31 years old, Ho Chi Minh City)
Your case is the group of increased pain sensitivity after injection. Normally we will have feelings of body pain that resolve on their own, very transient, many people do not know. After injection, sensitivity to pain increases. Many people have pain when raising their hands, changing positions, turning around, and pain in the chest area. But this is just increased pain sensitivity, not dangerous. These feelings will go away after about two or three days. Some people go away after about 5 to 6 days, depending on each person's body.
9:54 am
My 70-year-old mother has underlying diseases: history of stroke, cerebral hemorrhage, high blood pressure, diabetes, asthma, chronic sinusitis and is on stable treatment, with no history of allergies. Can I ask if I can get the vaccine? If so, what should I pay attention to? (Nguyen Kim Cuong, 50 years old, Binh Chanh, Ho Chi Minh City)
However, people with such underlying diseases should be vaccinated, early in the disease, to have a better chance of monitoring their health, ensuring the safety of the vaccinated person.
9:55 am
My mother had low blood pressure, coldness, weak pulse, and temporary loss of consciousness after anesthetic injection 30 years ago. Does that count as having a history of anaphylaxis? Can I get the Covid-19 vaccine, doctor? (Thanh Hai, 51 years old, Doi Can, Ba Dinh, Hanoi)
This situation of anaphylactic shock related to anesthetics or anesthetics is classified as a contraindication to the Covid-19 vaccine. Because according to regulations of the Ministry of Health, people with anaphylactic shock of degree 2 or higher will be contraindicated for injection. However, in this case, the world recognizes that if you do not have an reaction to the vaccine components, you can still be vaccinated. Like anesthetics and anesthetics, they can still be injected. But I recommend pausing to wait for additional instructions to ensure safety.
9:56 am
My father is on the vaccination preparation list. However, 3 years ago, my father had 3 heart stents inserted and is taking medication every day. I want to ask if my father is eligible for the vaccine and if he gets vaccinated, are there any risks?
Previously, in the old guidance, such cases would delay vaccination. But according to new instructions, such cases must be vaccinated. We need to remember that people with many such underlying diseases need to be vaccinated and closely monitored in the hospital. Cases like this can be very dangerous if ignored.
9:57 am
What advice does the doctor have for the community to ensure safe Covid-19 vaccination and soon achieve herd immunity?
Every vaccine that arrives in Vietnam is carefully considered by the Ministry of Health, carefully censored for quality, and monitored very carefully.
Second, if we have a vaccine, we will use that vaccine.
Even if you are vaccinated, you still have to ensure 5K and physical distancing, because vaccinated people are protected, while unvaccinated people are not protected. People who have been vaccinated can still be infected, so in addition to protecting themselves, they must protect the whole community.
And the faster they are vaccinated, the faster they will reach herd immunity, and the faster they will return to normal and return to production. You should not try to get vaccinated early and interrupt or cause trouble at the vaccination site. Protect your health, do well in 5K, protect the community to quickly return to a new normal state.
