and also quite effective at preventing infection. so basically what the studies published today by the cdc have shown pretty clearly now is that a three-dose strategy of the two prime shots plus a booster for the rna or j&j plus one really restores quite good efficacy at preventing infection and hospitalization and death and really should be the standard for the definition of fully vaccinated in this country. >> i've got to talk about this story. the nfl has told the remaining playoff teams in a new memo that unvaccinated players will no longer face daily covid testing, okay? saying they'll test players or staff who show symptoms. it sounds like perhaps they don't want to risk players testing positive during the playoffs or before the super bowl. am i wrong here? >> yeah, it's show time now.
