It's not clear yet if arm injected vaccines will provide mucosal immunity. They'll prevent serious disease but epithelial cells in the nose, mouth, and so on can still be infected and shed virus. It's the same for flu vaccines. There are nasal vaccines which do provide mucosal immunity like flumist but during heavy flu seasons only the old and young have access.
So, even if you're the required 2 months post vaccinated you probably shouldn't stop wearing a mask or social distancing until 100% of the population around you has either also been vaccinated or been infected and recovered.
When will the entire population be vaccinated or already infected? At current rates it may be a year or two.
- rmk 6y agoI have been downvoted elsewhere in this thread for saying that it's not clear whether the vaccine confers sterilizing immunity (or perhaps, for suggesting that restrictions will continue until children are vaccinated. Who knows!) Be careful what you say here, lest you get downvoted to oblivion!
- tim333 6y agoHopefully we'll get some data on to what extent vaccinated people can still spread virus. I hope not too much. There's at least one nasal covid vaccine on the way https://www.indiatoday.in/coronavirus-outbreak/story/india-nasal-coronavirus-vaccine-soon-trials-begin-nagpur-1756780-2021-01-07 https://www.indiatoday.in/coronavirus-outbreak/story/india-n... Apparently it works very well in monkeys. "We have completed studies on monkeys. It demonstrates 100 per cent sterilising ability."
