“If you and your own children are vaccinated against a disease, what difference does it make if someone else is not?”
It still makes a lot of difference to the society as a whole.
“herd protection”
Some people can not take the vaccine because of allergies. The injection of the vaccine presents serious medical problems to them. They exist and it is a very real problem for them.
If all others around them who can be inoculated are protected then the chance of the decease getting to them is very slight. They are literally protected by the immunity of the “herd” around them.
Maybe I’m missing something here. I thought if you are vaccinated for protection against a virus, you can still get — and CARRY — one or more strains of the virus, but you won’t be sickened by it. Isn’t that how vaccinations work? And if so, doesn’t this mean people who are unable to take a vaccine can still be exposed to the disease even if others ARE immunized?
