If flu shot vaccines are created from last year's flu, how can it protect against a different stem of the flu?

There are 3 strains: Every year a bunch of experts meet and decide what strains to put in the flu vaccine for the next season. They usually put in 3 different types, almost always one from the preceding year, and then two others that they decide on based on many factors.

Why are vaccines more painful than a normal yearly shot like the flu shot?

I'm not sure what: Vaccines you are referring to. One vaccine that patients often say hurts more than the others is Gardasil. The Flu vaccine actually does often cause pain, as does a tetanus vaccine. The soreness is from the body's immune response to the vaccine, which means it is starting to work. Some of the pain is also from the needlestick, itself, especially those vaccines which go into the muscle. ...Read more

Could I be allergic to just dippy-cooked eggs? It seems like I can eat scrambled and hard-boiled eggs. What's it mean for vaccines like the flu shot?

Yes: Some egg allergic individuals are able to tolerate well cooked or baked egg, but have issues with under cooked or raw egg.

Is the flu vaccine not working? I know drs urge it but if it doesn't work don't want to get it.

The trouble with flu: Yearly, we have at least 6 flu strains circulating the globe. The drug makers use surveillance data to pick the 3-4 top strains in March, and rush to put that into a vaccine. More strains would weaken the protection provided by the vaccine to those strains included. By the fall/winter, newer strains can develop and air travel brings them to you. The vaccine helps, but cannot stop all flus. ...Read more

I have never had a flu shot get the flu once a year. Are these super flus bring created by your vaccine eventually gonna get me and prob devour me?

Odd question: There are no "super flu bugs" created by vaccines. Vaccines are derived from strains created in nature. Nature sometimes mutates a flu strain to such a degree that a major part of the world population has never had a similar flu and it may reek havoc, as it did near the end of WWI. Since you get the flu every year, you likely have some partial immunity to new strains and don't get it as bad as some ...Read more

Is the yearly flu vaccine truly and definitely 100% safe for everyone without any shadow of a doubt? I'm scared of the flu but also scared of the shot

Always risk: There will always be some risk with any medication, vaccination, supplement, treatment or procedure. Vaccines are carefully studied for safety and efficacy before being recommended for routine use. Often times, the risk of severe illness or death from the disease being vaccinated against far outweighs the small risk of adverse event from receiving it. It's a personal decision.
