That would be what the goal would be. we would want to try to eliminate infection as much as possible. but i dont think that these mrna vaccines are able to do that to that degree. so we have to refigure our vaccine strategy. hopefully technology gives us the solution to have a better, more -- a vaccine that provides more sterilizing immunity. >> and it might not be fair to ask you this in 30 seconds that we have left, but tell us your thought about this new ba.2 omicron variant. how worried sho...

They wanted to get it right away. so those are probably the most important things you can do. you dont have to be holed up in your house. you can go outside where there arent a lot of people around. but we have to remember that this delta variant is very, very contagious. and transmission is easy. thats what were seeing with these breakthrough infections. we should remember no vaccine prevents all cases. we dont get whats called sterilizing immunity. we shouldnt expect that. and we need to take ...

One protein and the vaccines dont come close to conferring sterilizing immunity. people who are vaccinated still get infected. it only seems to be particularly good at blunting the disease. what that tells you therefore is that these vaccines in the vast majority of people are applying a nonlethal pressure. narrowly focused on one protein and of course a vaccine rollout is occurring over a long period of time. that is the recipe for driving -- >> laura: so your theory is it is exact opposite of ...

Of novel variances which are vaccines are focused on a single protein of the virus, so the virus only has to alter one protein and the vaccines dont come close to comparing sterilizing immunity. people who are vaccinated still get infected. it is only good at blending the disease. what that tells you is these vaccines and the vast majority people are applying a nonlethal pressure narrowly focused on one protein and the vaccine rollout is occurring over a long period of time. that the recipe for ...

Doesin clus something called sterilizing immunity. you are not going to get any manner of measles, not a mildly symptomatic infection. that virus bounces off you if youve gotten the vaccine. that is not the vaccine nor is it this kind of vaiccine, but people should still be encouraged to get a vaccine and that is the problem. the problem is we have probably 100 million people in this country would still need to be vaccinated. if we could get them vaccinated we wont talk about a lot of this. >> i...

The limited data available suggests the vaccines will at least partly reduce transmission, and the studies to determine this with more clarity are underway. There should be more data within the next couple of months. Until then, precautionary measures like masking and distancing in the presence of unvaccinated people will remain important.

| Updated: 9:55 p.m. There aren’t a lot of silver linings to the pandemic. One of them, from my eyes, is learning the speed at which the scientific community can progress when highly focused on a problem. Remarkably, we invented, tested, began manufacturing and distributing multiple very safe and effective coronavirus vaccines in under 12 months. It is wildly impressive that we did this. Yay, science! But that speed also means that my articles from recent weeks need a bit of an update, becau...
