The only thing of value in the post:

Most disease finds hosts

Does a 60% effective vaccine prove effective????? Never once.


Du.

60% of a group is more than once.

Example: Ten (10) people were given a drug to prevent an illness. It worked 6 times and failed to be effective 4 times. That is 60% effective.

That is how it is calculated.
