Flu Information
The FAQs below can help you learn more about the flu vaccine:
The flu vaccine helps to protect people from the flu. The viruses selected for each seasonal flu vaccine are updated each year. This decision is based on:
Currently, 130 national influenza centers in 101 countries study flu activity and trends all year long.
The traditional (trivalent) flu vaccine protects against 3 flu viruses: two type A viruses and one type B virus. A quadrivalent flu vaccine protects against 4 flu viruses: two type A viruses and two type B viruses. Both types of vaccines are approved by the US Food and Drug Administration (FDA) and are available in the US.
You cannot catch the flu from the flu vaccine. The flu vaccines that are given by needle are made with viruses that are killed (inactivated) or virus proteins that are artificially made (recombinant influenza vaccine). The viruses used to develop the nasal spray flu vaccine are alive but weakened (attenuated).
