Bill Gates warns THIRD vaccine dose needed to beat coronavirus variants | Science | News

Mr Gates then shared his foundation was financing research in South Africa on whether the AstraZeneca, Johnson & Johnson and Novavax vaccines were as effective against the South African and Brazilian variants.

In a worrying sign, he said: “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.”

Mr Gates also suggested additional COVID-19 shots may be needed if the virus is not eradicated and added: “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.”
