“The right thing to do would have been to vaccinate every healthcare worker in the world, so any country anywhere is prepared to take care of the pandemic. And then move to the people at most risk of dying… Of course, the world didn’t work that way, and countries made a choice to get their vaccination up… The debate about boosters is complicated. So first of all, when medically necessary like… if you’re immunosuppressed and you don’t… have enough immune response to the vaccine, you need a booster, you should get it right away…. The question I think on everybody’s mind is do we continue to use vaccines to block [symptomatic infection], while people at high risk and healthcare workers haven’t been vaccinated, or do we now complete that primary goal of getting vaccines out to the highest risk and then continue the global movement of vaccines.”
