I believe we can add the vaccinated and the recovered, yes? About 25 million have recovered so far. That puts us at about 12% 'immune'.

As far as I understand those who were infected and recovered are still encouraged to get the vaccine. I’m not sure what that does to their priority in the vaccination queue though. I think the length of time recovery and vaccination confer are still not really nailed down

I think it is much higher, if you consider all the asymptomatic cases not counted.

Don't forget cross-immunity from other viruses. Numbers I vaguely remember put it anywhere from 5% to 30% depending on the country.

Every medical professional I know /am related to has indicated that getting covid only grants 90 days immunity. Across state lines, they all have said that herd immunity visa infection is impossible as it requires everyone to be infected within a three month span.

      The first source just measured declining antibodies, but the real picture about immunity is more complex than that. The second doesn't say what you think it says.

  In that case there will be tens of thousands of examples of people having covid back in April and having had it again in October and even again now.

  If getting the actual disease only results in 90 days of immunity, then will a vaccine do any better? Is there precident for immunity via vaccine being longer-lasting than immunity as a result of contracting the actual disease?
  - kuschku 6y ago
    That’s why the vaccine needs two applications. With only a single application, you’d also only get 90 days. Additionally, a lot of the additives in the vaccine are intended to make your immune system perceive it as much more of a threat (while a virus will try to be perceived as not a threat), increasing the priority your immune system gives the virus (and the duration it will be able to stay immune)
- giantDinosaur 6y ago
  This is charitably a misconception, and very possibly an outright lie. Nothing indicates a 90 day cutoff to immunity. On the face of it, that should make anyone reading this sceptical.

    I was very skeptical of it as well, and had the same reaction to the medical professionals saying this. Their off the cuff "oh, yeah, ninety days, makes sense" led to me believe them. Note as well I'm referring only to catching covid - not the vaccine. There's this early study from July as well https://www.nejm.org/doi/full/10.1056/NEJMc2025179?query=featured_home https://www.nejm.org/doi/full/10.1056/NEJMc2025179?query=fea...
