Another stunning feature of the Merck vaccine is that out of about 1,200 women who received it, the protection rate was 100 percent. That doesn't mean the vaccine is "100 percent effective," as you may have read. Surely it won't be when given to hundreds of millions of women, each with their own unique genetic make-up and some of whom would have immune systems compromised by AIDS and other diseases. But such a high protection rate in such a large clinical trial is what is known in strictly scientific terms as "awfully damned good."
