It's quite a bit less. Measles is far more contagious than Covid-19 as it can survive in the air for a long time and you only need a tiny viral dose to get infected (Covid-19 appears to be far less stable, and it requires a higher dose to infect someone). They're estimating we need 65-70% for Covid, possibly less if there's low density. But the world is nowhere near that right now.
What is the herd immunity level for Covid-19? If it’s 90 percent for the flu, is it safe to assume that it’s about the same for Covid.
*not the flu, measles
