I am not a medical expert, so I will just speak from experience.
I have had many vaccinations over my half-century life. I have never had and adverse side effects.
I was of the first generation of kids to get a polio shot. I remember our entire elementary school lined up in the school auditorium and get them "assembly line" style. It was considered a miracle shot at that time because the threat of polio was so awful.
I don't remember all the other childhood vaccinations I got except smallpox. I remember that one because it was a multi-prick vaccination, not a regular "shot". I still have the scar, although it is very faint now.
I never got vaccinated for chicken pox, mumps, or measles as a child. Those were not available at the time. I eventually caught chicken pox, mumps, and measles.
When I travelled overseas I got typhus and yellow fever shots. When I joined the Navy I got a whole series of shots thru the "gun" assembly line. Pow, pow, both arms! If I dig out my yellow shot record I could be more specific.
Flu shot? For many years while I was in the Navy and the Reserves, I got the annual flu shot. No problems. I did not get one this year because of the shortage, and because I am not in the high risk group. I am not sure if I would get one next year if available.
Hepatitus vaccine? I asked the doc at VA if I should get that. He said no, because I am not in the high risk group. The reason I am concerned about hepatitis in particular is because both my parents died of liver disease. (They died way too soon.)
I grew up a child of the 50's. Doctors were gods and modern medicine was miraculous. Better living thru chemistry. It is hard to shake that background. I grew up expecting great things from medications. I have since become more skeptical and cautious. I do more research, and try to use the least invasive and most natural health methods when possible. However, I do go under the knife at times with confidence.
I can't wait to read your comments about vaccinations. Ooooh, nooooo!
