Flu shot safe: The influenza vaccine by injection is safe. It is a killed vaccine and not able to cause the flu. Side effects are usually mild and short lived. In immune deficient patients, usually avoid "live" vaccine such as nasal flu vaccine. ...Read more

Flu Shot (Definition)

Also known as influenza vaccines, flu shots are given out once a year to protect against the flu. The flu shot stimulates the immune system to build antibodies to three or four strains of flu viruses in the hopes that it will offer protection from the current strains present in the community.

Can flu shot weaken your immune system to where you can catch sinus infections ? My wife thinks that she want me to try just one year to go without

Can flu shot weaken your immune system to where you can catch sinus infections ? My wife thinks that she want me to try just one year to go without

Urban myth!: Influenza immunization has no effect on the immue system, except to help make the recipient immune to flu. It doesn't cause a minor case of influenza, fever, or anything like that; and it doesn't raise the chance of sinusitis or anything else. It is irresponsible to not get vaccinated against flu on account of such things. OTOH, we're almost at the end of flu season, so it may be too late to help. ...Read more

Aside from hand-washing, getting flu shot, etc., what are some good ways to boost the immune system during cold/flu season & avoid getting sick?

Great question!: Many people have opinions about "how" to boost the immune system. Practically speaking, there is no correct answer to this. The immune system is very complex and I am not aware of anything in particular that will globally "boost" this. A good diet, regular exercise, and an appropriate amount of sleep are good things along with the things that you are doing. ...Read more
