RAMAT GAN, Israel -An Israeli hospital administered fourth COVID-19 vaccine doses to a test group of health workers on Monday, in what it called the first major study into whether a second round of boosters will help contend with the fast-spreading Omicron variant.
On Monday, the Health Ministry said it was shortening the time between offering the second and third doses of COVID-19 vaccine to three months from five months in order to beat back rising infections as Omicron spreads. "The biggest question is, how significant is Omicron? It's clear to all that it is very contagious. But whether it causes very severe illness - that's the most significant question," said Gili Regev-Yochay, who is running the Sheba trial.
That card is going to look like the Stanley Cup soon.
