I got flue shot but I got cold?

[talloak]

Flu shots take weeks to create the immune response needed to fight off the varieties in the shot. It does nothing against colds. Also, there is no guarantee that it will prevent all flu viruses because they manufacture them a year in advance and they can only guess which ones are likely to be big next year. Flu shots do not ever make you sick so your infection was just a coincidence.

Those are two different things. A cold is not a mild flu. A cold is caused by a rhinovirus and the flu is caused by a flu virus. Different disease. A flu shot doesn’t prevent all illness.

You got a flu shot, not a cold shot. Understand?

You can’t catch a cold from a flu shot.
