Do we have conclusive numbers on how long these vaccines last? I’m reading that Pfizer lasts about 6 months? There’s no way there won’t be a surge again next summer if that’s the case.
There is some evidence that booster shots after 6 months can provide better even better protection than the second shot after 3-4 weeks, but it's not clear whether they will be necessary yet, especially when so much of the world is still desperate to get the first two shots in peoples' arms.
