Didn’t Israel test antibody levels post-1st dose, and come out with results that it’s around 50% by week 2 and 90% by week 3, before taking the second shot?

If I’m not mistaken the claims that the levels are low (and efficacy only 50%) were because some sources took average of days 1-21 instead of 14-21.

I'm not sure what your 50% and 90% refer to. 50,90 percent of what? There were tests showing an order of magnitude more antibodies a week following 2nd shot (e.g. [0]).

The efficacy claims were because disease levels took more time to drop off than what one would expect following lockdown+start date of 1st shot vaccination if 1st shot were effective. I lack the qualifications to evaluate these claims, but I can tell you all Israeli HMOs prefer the 2 shots regimen.

Those percentages are percent of vaccinated people who have not been observed with symptoms
