Infectious Disease

Influenza virus (Influenza) is a major cause of acute respiratory tract infections, which carry a high mortality rate among pregnant women, the elderly, and chronic disease patients. Getting vaccinated helps reduce the spread of influenza. Doctors strongly recommend that everyone receive an annual flu vaccine prior to the outbreak season.
Receiving the flu vaccine helps reduce confusion in screening for co-infections between influenza and COVID-19. Especially during COVID-19 outbreaks, flu vaccination among elderly individuals helps lower mortality rates from COVID-19. Furthermore, getting a flu shot before contracting COVID-19 can reduce hospitalization rates and shorten hospital stays compared to those who have never been vaccinated against flu prior to COVID-19 infection.
If you have already received 1 dose of the COVID-19 vaccine, can you still get a flu vaccine, and how long should you wait? The Department of Disease Control, Ministry of Public Health, advises 7 high-risk groups, including:
You can receive the seasonal influenza (Flu) vaccine before, during, or after receiving the COVID-19 vaccine.

It is recommended that everyone, especially those in high-risk groups such as the elderly or people with underlying conditions, receive the influenza vaccine to boost immunity and help prevent the spread of flu outbreaks.
