A third dose of c****av***s v*****e may be needed to prevent serious cases of new variants of the disease, Bill Gates said Tuesday. The billionaire philanthropist's comments come amid to the growing concern that current v*****es are less effective against the South African and Brazilian variants.
"The discussion now is do we just need to get a super high coverage of the current v*****e, or do we need a third dose that's just the same, or do we need a modified v*****e?" Gates told "CBS Evening News" anchor and managing editor Norah O'Donnell.
"All five of the companies that have U.S. v*****es are looking at making that modification and adding that in so that people who've already had two shots might need to get a third shot," he said. "I think it's reasonably likely that we will have a tuned v*****e just to make absolutely sure that as these variants hit the U.S. that they're not escaping from v*****e protection."
Gates is funding studies in South Africa to determine whether the AstraZeneca, Johnson & Johnson and Novavax v*****es were as effective against the more contagious variant.
"AstraZeneca in particular has a challenge with the variant. And the other two, Johnson & Johnson and Novavax, are slightly less effective, but still effective enough that we absolutely should get them out as fast as we can while we study this idea of tuning the v*****e," Gates said.
If the c****av***s is not eradicated, he said, additional shots may be necessary in the future. "Probably not yearly, but as long as it's out there, we want as many Americans as possible not to be spreading it to each other," he said.
Dr. Scott Gottlieb, the former head of the Food and Drug Administration, told CBS News' "Face the Nation" on February 7 that he believed the v*****es currently being distributed in the U.S. would offer "reasonable protection" against the new variants, even if they are less effective against the new strains. Still, he said, it may also be necessary to administer booster shots in the fall.
