Here's how I understand it. Vaccines aren't weak variants, but usually are inactivated forms of the virus. So the inactivated form is not as virulent and won't be highly reproduced in the body. They may use animal or fetal cells in the vaccine to get the virus into the body. A virus is basically a strand of DNA it RNA surrounded by prote…

They may use animal or fetal cells in the vaccine to get the virus into the body. A virus is basically a strand of DNA it RNA surrounded by protein. Maybe if you just injected the viral proteins, the body would break down the proteins and DNA before antibodies would be produced.
It's hard to get an inactivated form of the flu virus because it keeps mutating every year. So the inactivated form from one year won't be effective the next.
To me, the difference between a vaccine and your sentence on arsenic and chlorine gas is that vaccines generally produce antibodies. The CDC changed a definition of a vaccine from something that makes you immune to a disease, to something that generates antibodies in the body. Generating antibodies in and of itself doesn't necessarily make one immune to a disease, hence the low efficacy of the flu vaccine.
I doubt I will take another vaccine in my entire life! I don't think I can trust any vaccine any longer, even those purporting to be made from an inactivated virus.
