Third shot may be needed to combat new coronavirus variants, Bill Gates says


A 3rd dose of coronavirus vaccine may be needed to stop critical circumstances of new variants of the illness, Bill Gates mentioned Tuesday. The billionaire philanthropist’s feedback come amid to the rising concern that present vaccines are much less efficient towards the South African and Brazilian variants.

“The discussion now is do we just need to get a super high coverage of the current vaccine, or do we need a third dose that’s just the same, or do we need a modified vaccine?” Gates advised “CBS Evening News” anchor and managing editor Norah O’Donnell.

“All five of the companies that have U.S. vaccines 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 mentioned. “I think it’s reasonably likely that we will have a tuned vaccine just to make absolutely sure that as these variants hit the U.S. that they’re not escaping from vaccine protection.” 

Gates is funding research in South Africa to decide whether or not the AstraZeneca, Johnson & Johnson and Novavax vaccines had been as efficient towards the extra 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 vaccine,” Gates mentioned. 

If the coronavirus is just not eradicated, he mentioned, further photographs may be vital sooner or later. “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 mentioned. 

Dr. Scott Gottlieb, the previous head of the Food and Drug Administration, advised CBS News’ “Face the Nation” on February 7 that he believed the vaccines at the moment being distributed within the U.S. would supply “reasonable protection” towards the new variants, even when they’re much less efficient towards the new strains. Still, he mentioned, it may additionally be vital for booster photographs within the fall.
