What a vaccine's efficacy rate actually means. • Sign up for our newsletter: http://www.vox.com/video-newsletter • In the US, the first two available Covid-19 vaccines were the ones from Pfizer/BioNTech and Moderna. Both vaccines have very high efficacy rates, of around 95%. But the third vaccine introduced in the US, from Johnson Johnson, has a considerably lower efficacy rate: just 66%. • Look at those numbers next to each other, and it's natural to conclude that one of them is considerably worse. Why settle for 66% when you can have 95%? But that isn't the right way to understand a vaccine's efficacy rate, or even to understand what a vaccine does. And public health experts say that if you really want to know which vaccine is the best one, efficacy isn't actually the most important number at all. • Further reading from Vox: • Why comparing Covid-19 vaccine efficacy numbers can be misleading: https://www.vox.com/22311625/covid-19... • The vaccine metric that matters more than efficacy: https://www.vox.com/22273502/covid-va... • The limits of what vaccine efficacy numbers can tell us: https://www.vox.com/21575420/oxford-m... • Vox.com is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.
