Is vaccination really healthy?

I know you are talking about pets so I hate to change the subjec, but there
has been humans that have died or have became ill because of vaccinations
that the doctors insisted for them to take......

All I am saying is vaccination may not be as healthy as we believe it to be, and
we could possibly be doing more harm than good-----unaware.

Animals just need to be cared for.
Given baths,clean food, clean water, and kept in a hygenic environment.
