Originally posted by luftfluss The monkey wrench is that immunity looks quite temporary. Between 3 months for a gentle infection to 5 years if it was severe, 16 months median. That makes the goal of somehow getting herd immunity not much of a thing. Boosters and masks will likely be a way of life for the rest of it. We can at least reduce the numbers and outbreaks to a much more tolerable level.
Big questions are how long does protection from hospitalization/severe last with vaccine? Symptomatic protection declines 2-6 months.
Will it mutate again and get worse, as it did with Delta
Either of those could mean flare ups indefinitely as other nasty diseases have done in the past. For now it will flare up as it just did in the USA indefinitely in the pockets of unvaccinated and effecting some percent of vaccinated as well, though they’ll be protected for now from severe cases. Note my coworker who didn’t die, but it wasn’t pleasant (below) and is vaccinated.
“ Reinfection by SARS-CoV-2 under endemic conditions would likely occur between 3 and 63 months after peak antibody response, with a median of 16 months. This protection is of less than half the duration revealed for the endemic coronaviruses circulating among humans.”
From the lancet last week on a study of durability of immunity.
I go in for round three of Pfizer next week. Still wearing N95’s at work (I work with a ton of soldiers in close quarters, who don’t show symptoms in general when they get it).
I just had a coworker, aged 29 get covid a few weeks back, vaccinated, no comorbidy’s in good health, not overweight etc. Was on oxygen for two weeks and in hospital twice. So best to stay vigilant as it’s not over.
