How does it compare to a vaccine ?

Anecdata: I had a very mild case at the end of last October. Three weeks ago I got my first jab of BioNTech/Pfizer. Ten days after that I did antibodies test. The amount was 750 times of that required to be seropositive. Much as I expected. Just got my second jab, but won't be doing antibodies test anymore.

Indeed, in France, if you had COVID within a certain time period, one jab counts as fully vaccinated.

Who knows what, if any, differences there are in long-term immunity, but so far, infection + 1 vaccine is looking like it produces very good immunity, even against known variants and even against the original SARS. In a petri dish anyway.

Out of curiosity, what was the number (and unit) you got, and which antibodies were tested?

I still had antibodies in March, 1 year after having Covid, but the doctors didn’t want to say if the level was indicative of immunity or not...

Probably depends how many boosters you get, and the vaccine type. All the vaccines in widespread US use don't contain the whole virus, so it could have a reduction in T-cell protection, but that's not what's being talked about. It's quite possible the antibody levels in blood after five years would no longer be neutralizing after five years, looking at other subunit-ish vaccines.

Yes, the vaccine type is very important. Currently, of the Seychelles, Israel, the UAE, Chile and Bahrain—respectively the world’s five most vaccinated countries—only Israel is not fighting to contain a dangerous surge in Covid-19 infections.

What those four countries have in common is their use of Sinopharm. It seems safe to assume that the efficacy of Sinopharm has been significantly exaggerated.

It is unfortunate that it has been elevated to the same level as vaccines that have been rigorously tested and validated.

For countries using US/EU-approved vaccines —- Pfizer, Moderna, J&J, and Astra Zeneca —- increasing vaccination rates are clearly showing a “decoupling” of cases and hospitalisations. That prevention of severe disease is their stated objective, that’s all we need to end the pandemic, and they are clearly a huge success story.

Didn't the CCP even admit its lack of efficacy?
