Think of it this way. You're living in your mom's womb, then you get born. Your mom's womb is pretty darn sterile. Suddenly, you're born and you're literally being assaulted by every germ around you, with probably thousands of them being encountered by your immune system every day.
How are a *few* shots (7 may seem like a lot to you) going to compare against thousands of things all hitting the naive immune system of an infant all at once, starting from birth, every day?
Or is it the fact that the particular antigen is injected into a muscle supposed to make it more scary?
It just seems to me that the amount of antigens presented to someone during a shot is just completely dwarfed by the natural exposure. It's just that the select few antigens in the shots just happen to be particularly helpful in helping you resist *actual serious disease*.
Also, I can't find your "varicella vaccine mortality rate of 1 in 30,000" information on the CDC website, Please provide source. What I found was this: "Other serious problems, including severe brain
reactions and low blood count, have been reported after
chickenpox vaccination. These happen so rarely experts
cannot tell whether they are caused by the vaccine or
not. If they are, it is extremely rare." I think we would hear about it if thousands of people died from the chickenpox vaccine.
Furthermore, they also say that only the FIRST dose has such an extreme reaction. So the "much higher than 1/30,000" claim you make is extremely dubious.
