If vaccines were 100% effective you might be right, they are not. The best I've seen is 95%.Yes. You go everywhere totally unaware of who has had what vaccine or not. So my question stands, do people take vaccines to protect themselves from a virus, or do they take it to protect themselves from others?
Now this isn't rocket science, you take a polio, smallpox, covid etc.. vaccine to protect you from polio, smallpox and covid etc.. Whatever anyone else does, is of no consequence.
If you went shopping, do you phone the store in advance to make sure every customer has had a polio, smallpox, covid vaccine etc..?
