I mean the situation where someone gets Covid and survived. Do they then have protection from getting Covid again? Is the protection as good as the protection from the vaccine? Do we know anything about this? Just wondering

(8,579 posts)Here are some recent studies - the first still needs peer review. .
And ....
The variant was 27 times more likely to break through Pfizer protection from January-February and cause symptoms than it was to penetrate natural immunity from the same period https://www.timesofisrael.com/study-covid-recovery-gave-israelis-longer-lasting-delta-defense-than-vaccines/
Natural immunity from contracting coronavirus provided Israelis with longer-lasting protection against the Delta variant than two shots of the Pfizer vaccine given early this year, new Israeli research suggests.
The study by Maccabi Healthcare Service looked at individuals who had either gotten two shots of the vaccine by the end of February or tested positive for COVID-19 by that time.
It compared 46,035 Maccabi members who caught the coronavirus at some point during the pandemic and the same number of double-vaccinated people.

(21,655 posts)I don't much give a fuck about any of those people. The small number of people who have legit medical reasons... OK, that is fine... In fact it because of them it is so important for the rest of us to get vaxxed... but the rest... Fuck 'em. If they die, they die... I kind of hope a lot of them do die. A shame they will also kill family, friends and strangers but at least they will also be dead. I had some sympathy for them up to a point but now their stupidity and willful ignorance is simply tiresome... Let them die.
Honestly... I don't see how anyone could still have a single shit left to give for them

(1,671 posts)Natural immunity or COVID-19 vaccine mandates? Some study somewhere proves your point (opinion)
A study from the Centers for Disease Control and Prevention the other day said that 83 percent of Americans age 16 and older have some kind of immunity from COVID-19 either through prior infection or because theyve been vaccinated.
The study said that a lot more people likely had been infected than initially thought because they had mild cases or no symptoms and were never tested. They never made it into the infection databases.

(14,782 posts)available data so far (with new variants constantly emerging, things could always change in the future). There are many popular/vernacular (i.e. not technical/specialist literature) articles about these findings.

(5,928 posts)The findings also focused on patients who received the Pfizer-BioNTech vaccine in early 2021. Other research from Israel has recently suggested that vaccine-induced antibody levels wane after several months, but booster shots can enhance immune response. How natural immunity compares to vaccine-induced immunity with booster shots remains unknown.

(7,611 posts)A lot of people who are never going to get vaccinated so natural immunity is about it for them. So how good is that?

(35,191 posts)One one vaccination after having had COVID already (results really good), the other for immunity just from COVID (no vaccination), pretty good. What "pretty good" means depends on the study, real-life studies aren't always well controlled.
The gap I'm waiting to be filled is immunity level/duration if you contract COVID *after* you're fully vaccinated. Might be tough to control that, because a lot of vaccinated people will have had COVID pre-vax (but then again, you'd expect those to be at sharply reduced risk of symptomatic COVID, so many that can just be quantified and statistically handled).

(3,796 posts)A higher rate of breakthrough cases than there is of re-infection. But being vaccinated leads to a lower re-infection rate, so even if you caught it it's a good idea to get vaccinated.
