Are you contagious after getting a flu shot if you present symptoms?

Not from flu shot. If you get the flu shot, you are getting a dead flu virus. You cannot get the flu from the shot. Thus you are not contagious. People can have reactions to the flu shot that they mistake for getting the flu. These reactions are also not contagious. The symptoms could also be from a totally different virus that is just a coincidence in timing - this could be contagious. Read more...

My nanny caught the flu from her flu shot. And yes I'm certain it's what caused her symptoms, happens to her yearly after her shot. Is she contagious?  

Yes, if she has flu. A person can catch the flu right after a flu shot, but not from the flu shot. An unlucky person can catch the flu after a flu shot several years in a row, but not due to the flu shot. The flu shot does not contain live viruses (but the nasal spray flu vaccine is alive). If she has the real flu, then she is contagious for a week or so. Read more...
Not the flu. If she got the flu shot (as opposed to the nasal spray), it is impossible for her to get the flu from the actual flu vaccine. Perhaps she has a different virus giving her the current symptoms, or a mild reaction to the vaccine. If this happens every year, reaction seems most likely. She will not be contagious in this case and poses no contagion risk for your family. Read more...

Is the flu contagious before symptoms appear? & will flu shot have some protection against other strains even though it's not a good match this year?

Yes. You are contagious before you have symptmoms of the flu and this is the case with many viral infections. This is why they spread so easily. Once you get symptoms of the flu most people feel so badly they know and others know to stay away. Once you have been exposed the flu shot will not prevent as you need close to two weeks to prime your system. It is only about 25% effective this year. Read more...

Flu for 5 days despite of flu shot. Still have fever, aches, chills, no appetite, mild cough, headache, exhaustion. Still contagious? How long?

See your doctor. One of the biggest problems from the flu is the chance of secondary bacterial infections, including sinusitis and pneumonia. Fever for 3-4 days can be normal, but with 5 days of it, it is time to be seen. You are contagious for 5-7 days after the onset of symptoms. If you have shortness of breath, dizziness, blurry vision, go to the ER. The vaccine only protects 60% of folks. Read more...

Side effects of flu shot in infants? Also, would they be contagious? 6mo got flu shot on Friday and has had elevated temp no fever runny nose cough

Unrelated. The child's symptoms are unrelated to the vaccine. It is possible the child came in contact with someone with a cold around that time. The flu vaccine is a dead virus vaccine, does not cause illness, nor is the patient who receives the vaccine contagious. Read more...
