Who's to say that maybe the 95% group is different between vaccines?

There is a study going on in the UK, where people were given two DIFFERENT vaccines to boost the immunity even farther..

Interesting study. I wonder if they will do the "salvage" study as well.

For example, the two main chemotherapy regimens for advanced Hodgkin's are MOPP and ABVD. Both are 90+% effective alone. When both regimens are given simultaneously, they are 96% effective. But, if you let the patient fail on one of them and then start the other, you get 99% efficacy. So sometimes more all at once is not better
