She does not, but she and her whole family had Covid this past March so we're not worried.

. . . curious as to whether there's any data about how long Covid-related antibodies survive vs. vaccine antibodies. Anyone know?

When considering this in the context of your prior question, keep in mind that asymptomatic spread from someone with antibodies can still be a concern.
Development of antibodies after vaccination has been more predictable than after infection.
Nearly100% seroconversion following vaccination has been shown in studies such as this and this (some underlying conditions can obviously reduce the likelihood of seroconversion).
A recent study that reported that antibodies did not develop in 36% of COVID cases of differing severities and this study that reported seroconversion in nearly all cases of mild and moderate disease indicate the extremes of what has been observed following infection.
Because natural infection produces antibodies to not just the S protein used for vaccines and because there are additional components of the immune system, the question of vaccine vs. natural immunity does not end here.
Advocates of vaccination for those with prior infection cite this recent study showing that those who have had COVID and are not vaccinated are more than twice as likely than those who are fully vaccinated to be reinfected. Conversely this study reports stronger and more durable protection from natural immunity than vaccination (although it also provided support for single dose mRNA vaccination to augment natural immunity).

Maybe you should all stop watching American news 24/7.
I’m so glad I am here

These papers say the opposite Andy. The papers say that among people who have all been infected, those who are also vaccinated are half as likely to get re-infected. It is an argument to get vaccinated even if you already had the sickness. Separately, they also say that those who are vaccinated but have never been infected are 5-27 times more likely to get a breakthrough case compared to the likelihood of an unvaccinated person who had been infected are of getting re-infected. The range of a previously infected but unvaccinated person being 5 to 27 times safer than a vaccinated-only person depends on a whole pile of things including how long it was from the vaccination because their effectiveness seems to decay over time, but this paper and other similar ones seem to leave no doubt that having previously caught covid is a much stronger defense than the vaccine by itself.
Studies like these are what are putting pressure on governments to accept a previous infection as a valid equivalency for the vaccine passports, since they are far safer to the general public than a mere vaccinated person.
This thread is no longer an SBH specific thread. More appropriate for EE.
We’ll agree to disagree. Nothing unusual there.
i assume only vaxxed femmes de chambre for you ?
Based on all this I would demand that maids wear masks when cleaning the villa.
Sorry but I disagree. The CDC study in Izzy’s post shows a higher degree of protection for vaccination than one who was infected. The other article has not been peer reviewed and is not considered a scientific study.
