I can dig it up. It’s from a study out of Scotland if I recall. It was 35 days. But this only refers to the first shot. It does not include people who got 2 doses.
Also should be noted what we are actually measuring. They were measuring rates of hospitalization or death. So 90%+ reduction during the first 4-5 weeks, but reduction in hospitalization or death dropped to 60% range at day 35 among those who only got the first dose. It may have some biases e.g. who decides when to administer a patient to the hospital or when, vs sending them home for bed rest. So I am not wholly confident in these or any statistics related to covid.
I appreciate the info.
