When is the most suitable vaccination
Can not produce enough protective antibodies immediately after receiving the influenza vaccine, and it usually takes 2 to 4 weeks to play a protective role.
Inoculation with the live attenuated nasal spray influenza vaccine can produce IgA in the nasal mucosa to form a mucosal barrier within 5 days.
Therefore, in order to ensure that recipients receive immune protection before the high incidence of influenza season, it is recommended that everyone get vaccinated as soon as possible after they have influenza vaccine. Now is the best time for influenza vaccination. Can
