The Statistical Secrets of Covid-19 Vaccines

Wired  

The creation and distribution of vaccines against Covid-19 has been as close as science gets to a miracle—the culmination of centuries of infectious disease research, a mastery of viral genomics, the creation of a whole new kind of vaccinology, and speed in the face of crisis. People who are harder to reach and people who might be “vaccine hesitant.” They resist getting vaccinated because—well, actually, that’s confusing. That, plus confusion over the statistical measures of how well vaccines work, might be providing quiet justification for some people’s hesitancy. But “efficacy” has a specific meaning in the world of vaccine statistics, and it’s not “Hey, if I get a shot, my chance of getting Covid is now just 5%!” Ha, no, you dope. Since the basic function of a vaccine is, indeed, to keep people from catching a disease, you can imagine that this number can end up being pretty big—regardless of those people’s chances of getting Covid.
