“Bad news coming from Israel this morning.” This was announced on Twitter by Yaniv Erlich, an Israeli-American scientist, associate professor at Columbia University, relaunching new data from the Tel Aviv Ministry of Health on the protection of the anti-Covid vaccine against the Delta variant of the covid.
“The Ministry of Health – Erlich writes – reports that Pfizer’s effectiveness in protecting against the Delta variant drops to 64% from 94% against other strains. This has important implications for herd immunity and the ability of the virus to evolve further “.
