It is not too late to get the annual flu vaccination! This month from December 5-11, 2021 was National Influenza Vaccination Week. The flu is a significant public health concern, and this week served as a reminder to people that there is still time to get a flu vaccine.
It takes about two weeks after receiving the vaccination for antibodies to develop in the body and provide protection against this virus. As a result, it is best to get vaccinated before influenza viruses start to spread and peak between December and February. The flu viruses change constantly so flu vaccines are updated each season for protection.
