Not my field but just looking at that I see variations as big as the signal they are supposedly detecting. Looks an awful lot like noise.

And note that it's possible for a vaccine to have a negative survival benefit yet be a good idea--in a population with herd immunity a vaccine provides little benefit to those who receive it so long as enough people receive it to provide the herd immunity. But if too many don't get it the risk from not getting it goes up considerably. Look at what has been happening with measles--measles was basically unheard of, the quacks said not to vaccinate (remember, Wakefield was attacking a specific vaccine that he stood to profit from the controversy, Worm Brain doesn't believe in infectious disease in the first place), now we have people dying of measles.
