It'll be closer to 6-8 weeks since these early vaccines require two doses.

- throwaway189262 6y agoSubstantial 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.

- throwaway189262 6y agoI 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 Page 30 of https://www.fda.gov/media/144245/download https://www.fda.gov/media/144245/download 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
- davycro 6y agoAmazing! Thank you for digging! This is the most common question that I am asked at work.
- bawolff 6y agoThey 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.
