Did you know that globally, one person dies from influenza every minute?
Annually, an average of 250,000 to 650,000 people die from influenza infections. In addition to the burden of medical visits, lost working days, and the risk of hospitalization, patients can experience severe clinical progression and death. Evidently, seasonal influenza remains one of the major public health challenges over many years, yet it still receives insufficient attention from the public.

Influenza is often underestimated because it is confused with the common cold. However, completely unlike the common cold, influenza can cause unpredictable harms that, if neglected, may lead to dangerous complications such as otitis media, myocarditis, pneumonia, and even death.

Not only children, but anyone can be attacked by seasonal influenza viruses. Adults working in collective environments and offices are particularly susceptible to the seasonal influenza virus. The working environment is the setting with the second-highest rate of seasonal influenza transmission, right after hospitals.

Therefore, the World Health Organization recommends ANNUAL SEASONAL INFLUENZA VACCINATION for effective disease prevention and to reduce the burden of treatment costs and lost working time. Seasonal influenza vaccination helps reduce the risk of hospitalization by 57%, decreases medical examination visits by 42%, reduces lost working days by 32%, prevents the transmission of seasonal influenza to colleagues, relatives, and young children living in the household, and alleviates stress and work overload caused by taking medical leave due to influenza.

The changing seasons provide favorable conditions for pathogenic bacteria and viruses to thrive, triggering outbreaks and community transmission, particularly among the elderly and young children with weak immune systems. November is a time of erratic weather changes; the Southern region experiences sudden rain and shine while the Northern region begins to experience cold winds accompanied by dry weather, creating favorable conditions for illnesses such as influenza, allergic rhinitis, measles, hand, foot and mouth disease, respiratory infections, or the exacerbation of chronic conditions.

Currently, the Vaccination Clinic of Hanoi Medical University offers seasonal influenza vaccines covering two influenza A strains (H1N1, H3N2) and two influenza B strains (Yamagata, Victoria) for children aged 6 months and older as well as adults, especially older adults and those with underlying medical conditions. Let us proactively prevent influenza to protect both our families and the community!
