Substantial resistance is built up after 8 days from the stuff I've read. Yeah immunity level is not great, but look at mortality in the studies.

AFAIK nobody that got even a single dose ended up in the hospital. That's huge if true. That means hospitizations will plummet well before everyone is through their second dose.

Do you have a citation for this claim? I heard or read similar but then couldn’t find the source.

I dug deep for this lol... It looks like somebody ballparked it from a graph, I read it in a news story I can't find. It looks like COVID incidence among study participants comes to a screeching halt somewhere around 8-12 days after first dose

See this graph > Cumulative Incidence Curves for the First COVID-19 Occurrence After Dose 1, Dose 1 All-Available Efficacy Population

Also keep in mind this graph is probably based on COVID diagnosis date. Since it's unrealistic to test positive the day you contract COVID, I think it's reasonable to say it might even be effective from day 3-5 on

Amazing! Thank you for digging!

This is the most common question that I am asked at work.

It’s 12 days

They allegedly have partial immunity after the first dose (how partial i have no idea, and it might fade really quickly if you don't get the second), but its possible its enough to have some effect if enough of the right populations have the first dose.
