Oh No Flu Didn’t! Getting Sick After The Flu Shot

Oh No Flu Didn’t! Getting Sick After The Flu Shot

ID 100278347It’s the last thing you think will happen. You try to listen to the professionals and protect yourself by getting the flu shot, and then all of the sudden you’re feeling bad! While the majority of people who get the flu shot have no problems, a select few will experience some not-so-fun symptoms. Here’s what to look out for.


Contrary to rumored belief, a flu shot cannot give you the flu. Some people may feel weak and overall crummy after the flu shot. That’s most likely because the person’s immune system is making protective antibodies in response to being vaccinated. It takes about two weeks for the flu vaccine to kick in, so some people may be exposed to the flu virus and get sick before they are protected, or get sick from a strain not included in the vaccine.


Some of the side effects from a flu shot can include soreness, redness, or swelling where the shot was given. Some people experience a low-grade fever or aches, but these symptoms usually subside within one to two days.

Serious allergic reactions are very rare. Signs of an allergic reaction to a flu shot can include breathing problems, hives, weakness, rapid heartbeat, or dizziness. If you’re having an allergic reaction to a shot, it would be within a few minutes to a few hours after receiving it. You should let your medical provider know beforehand if you’ve had allergic reactions in the past, especially to eggs

Still, the flu vaccine is the best way to protect yourself from the flu. The symptoms you might have after getting the shot are much more mild than the flu virus, which can put you out for weeks. If you experience any serious symptoms or mild symptoms lasting more than two days, see a medical professional. Flu shots are available at ProHealth and ProHealth Medical Care now for just $32, with or without an appointment.
