One thought on “Can the flu vaccine cause the flu?

  1. Arti says:

    Flu shots can cause allergic reactions in people who are hypersensitive to eggs, latex, or other ingredients in the vaccine. Life-threatening allergic reactions like anaphylaxis or angioedema are rare. The vaccines are either inactivated or recombinant, which means the viruses in the vaccines are not infectious or they are particles disguised as a flu virus to trick the immune system. No. a few people who get a flu shot develop mild flu-like symptoms as their body develops immunity, but flu shots can’t actually cause the flu.
