Influenza is different from the common cold. It is caused by the latest influenza virus infection that mutates every year.

The symptoms are much more serious than the common cold. It will cause body aches, cough, runny nose, fever, etc., and may even directly lead to death. Vaccines have become a necessary means of preventing epidemic outbreaks.

 

The World Health Organization (WHO) predicts candidate influenza viruses in the northern and southern hemispheres every year, as a wind vane for vaccine production by vaccine companies.

 On February 24, WHO officially released the recommended components of the 2023-2024 northern hemisphere seasonal influenza vaccine, so that countries and vaccine manufacturers can develop and produce influenza vaccines. Please note that there is an update for Type A strains!
