I can't wait till this Covid-19 vaccine, Covaxin, comes to the US. This is what I'm waiting for.

40. I doubt if there is enough data to be meaningful -

since there are only a few thousand cases. You'd have to have enough comparisons in the non-breakthrough cases to evaluate what made the difference (or even if there was a correlation).

I was always skeptical that the vaccines were reducing severity - but that was expressly what was tested. They only tested symptomatic people to determine if they had COVID. What they found was a reduction in symptomatic people (which would include a reduction in people with severe symptoms and death).

I think it is far more likely (which is being confirmed by recent data) that it reduces infection. (Now that they are testing for infection, even in the absence of symptoms.) If you reduce infection overall, you will also reduce severity and death. And - if all you are looking for is symptomatic disease you'll never find out whether it is reducing severity by reducing infection or by reducing syptoms.
