> Research shows that a previous coronavirus infection plus one dose of vaccine provides powerful protection — but concerns linger

This is one thing that’s been incredibly frustrating throughout this whole pandemic. Studies and research will show B, with no sign of A, however inertia/politics/fear/ignorance will continue to push A to the point of harm.

An example - a local store was insisting on wiping down the entire checkout conveyor with alcohol between every single customer until very recently, when we’ve know for a long time that you won’t get COVID from that.

I wish there was an easier way to figure out if you had COVID. As someone who's only got one dose so far, I would gladly skip the second one if I knew for certain I had COVID before, so someone else could get my second dose.

[never mind]

The article is not advocating doing anything unsafe or otherwise endangering others. The scientific question is quite valid - do we have to use our limited vaccine supply to ensure all get two doses or can we save a dose on those who already had COVID and give it to someone who needs it?

First paragraph of the article: “Many people who’ve been infected with the coronavirus might be able to safely skip the second jab of any two-dose vaccine regimen, a growing number of studies suggest. These results could help to stretch scarce vaccine supplies and are already influencing vaccination policies in some countries.”

US might have enough for everyone, and wouldn’t it be also great if we didn’t need as many doses and could share with hard hit places like India? I see this as a net positive if true.

Security theatre.

It’s about feeling safe, not about being safe.

Did you not get an antibody test at some point prior to the vaccine? That would have given you an answer with 99% certainty if you used a good one.

Antibody tests were only widely available in July-August, so people who got COVID in Feb or March often didn't have high enough antibody counts by that point to flag positive on the tests.

> France, Germany and Italy, among other countries, now advise only one dose of vaccine for people with a healthy immune system and a confirmed previous diagnosis. Many scientists who have studied immune responses to vaccination say such policies are a sensible way to make the most of limited supplies in countries that are racing to inoculate their populations.

At least for France, their Infectious Disease professionals go further. They're of the opinion that a second dose in someone that's been infected (within a certain range of time) is subjecting them to unnecessary treatment, wasted time and side effects for no/limited benefit.

It's not to make the most of limited supplies.

Auto-translation (with some readability tweaks):

> If the second dose of vaccine has already been administered to people with a history of infection with SARS-Cov-2, the data available to date do not show any difference in the safety profile apart from the occurrence of more common systemic reactions.

But questioning the value of a vaccine under any circumstances is ban-worthy in a lot of places.

Don't some antibody tests do this? I think antibody tests that detect antibodies to the nucleocapsid should be unaffected by the vaccines, which only spur resistance to the spike protein. See the section called "Binding Antibody Tests" here: https://creakyjoints.org/living-with-arthritis/coronavirus/c...

This is true of some - but not all - of the vaccines. The whole inactivated virus vaccines contain more than the spike, but the mRNA and vector vaccines only contain the spike.
