KEY POINTS

The U.S. is "nowhere close" to achieving herd immunity from Covid, a CDC scientist said Friday.
The proliferation of new, more contagious virus strains requires a higher proportion of the population to get vaccinated.
The outbreak could get worse as immunity decreases over time among vaccinated individuals or those who have recovered from Covid.

• 目前，以色列接種率沒有那麽高。那個數是每百人中用掉的疫苗數，第一、二針的總和。孩子們還都沒打，是潛在的傳播途徑。 -fuz- ♂ (190 bytes) () 02/28/2021 postreply 15:31:24
