“A vaccination makes catching a disease entirely preventable.”
Not entirely true. Google it.
“There is no good reason not to get one.”
There are many good reasons - including that some vaccines do not work, like the flu vaccine for older people.
“Whether its for children or adults is equally true.”
I agree there. No universal reason for adults or kids. Don’t universally work for either.
