I am a victim of "too much information"; please help me better understand diseases/vaccines.
According to Google, the documented success for the following vaccines, all of which have been developed/improved on for 50+ years, in preventing someone exposed to that disease from contracting the disease/being able to spread the disease to others, is as follows: (for simplicity we'll call this number the "protection % rating")
Flu A 37%
Flu B 50%
Chicken pox 82%
Mumps 88%
Measles 97%
Understanding that in addition to protecting against contracting a disease, that vaccines generally result in subdued symptoms for those who are vaccinated and still contract the disease when exposed:
1) Does % chance of contracting the disease equate to % chance of spreading the disease?
2) What characteristics of each disease accounts for the relative success/lack of success of the vaccine?
3) Is one factor the likelihood of each disease to mutate into different variants?
4) Based on clinical trials/other valid data, what would be the expected "protection % ratings" for each of the 3 Covid-19 vaccines currently available in the U.S.?
5) Would you expect the "protection % rating" to increase, decrease, or stay the same if a person is exposed to the UK, SA, or Brazilian variants?
