I know two people who had covid and who right now have a second covid infection by the british mutation. One of them also had their first vaccination.

unfortunately the false positives with our PCR testing is abysmal - in the US the CDC recommended cycle thresholds of >40 to signify a true positive. That is beyond insane - with the flu we recognize false positives are likely after just a CT of 23!

Your friends likely got sick twice, maybe once from covid and PCR tested positive twice. This is what the current literature understands - it's not impossible that you'recorrect, but unlikely.

I am being shunned by my family because of my lack of interest in the vaccine. I've had COVID and recovered. I also don't get a flu shot each year. I really like not putting things into my body, especially when year after year I may or may not "catch" these things but if I do, I always recover. I act responsibly and do not go out when I am sick. However, none of these facts or articles such as this will ever effectiv…

I look forward to when greater fact-based realities start to take hold again.

I think you are in for a long wait.

Does anyone know if PCR tests will find out if you've had the virus, after you had the vaccine?

Find a lab that offers Roche Anti-Sars-cov2-N test.

Interesting, is this one just for Pfizer as I've had Astra Zenica which I believe is a different set of spike protein DNA sequences?

Who said after recovery you need vaccine? Probably you just need to share official documentation from your government and official health body with your family. Afaik, recovered and vaccinated are treated the same currently.

PCR tests don't detect antibodies, they detect active virus. Antibody tests may be what you're thinking of. See: https://www.fda.gov/consumers/consumer-updates/coronavirus-d... I don't know the answer to your question, but it would make sense unless the antibody test(s) look for a specific type of antibody to COVID-19 that is produced naturally when infected and not just any antibodies that might be produced when vac…

incorrect, PCR tests detect any virus matter - active or otherwise. This is a very important distinction since we've seem to lost our minds collectively and label PCR tests with a cycle threshold of >40 as a true positive.

What happened in Manaus/Brazil(high re-infection rate even after the city reached herd immunity) shows that's not that simple and they clearly state it "though viral variants could dampen some of the protection they offer"

Listening to the Prof. Drosten Podcast (German only), he highly doubts that they actually had reached herd immunity before their second deadly wave.

He rather assumes something like 40% and then the mutated variant raged on (not badly affecting but infecting the 40% partially, and thus driving the infections).

I’m personally sceptical of putting too much faith in this, we’ve already seen a number of variants. Over my lifetime? Who knows what mutations we’ll see.

The common consensus among scientists now is that the vaccine works against most if not all variants as well.

If recovered people have longer term protection than vaccinated people (which is one possible interpretation of the headline's statement), would it make sense to first vaccinate someone and then expose them to the real virus, thereby generating the benefits with a much much lower risk or maybe even zero risk?

My girlfriend got infected about ten days after my second AstraZeneca jab. We didn't isolate. I got tested:

- Zero naturally-occurring antibodies (the kind you would get from having had COVID).

- Strong presence of vaccine-induced antibodies.

However, given the timing, I am still uncertain as to whether I contracted COVID during that post-second-jab 4 weeks when my girlfriend was infected (I gave blood for the test while I was still feeling bad in the weeks after the second injection, and I didn't spring for the 'currently infected' test, since the whole package of tests was pretty expensive).

If I got COVID now, would it not be handled exclusively by vaccine-induced antibodies, which means that any test for having had COVID in the future would still be negative?

I'm no kind of doubter, and I'm pretty sure the AZ double-jab helped me lately, but I'm not sure I'll ever know if I was ever infected, to be honest.

Earlier quoted context omitted.

There's some evidence that a second dose of mRNA vaccine isn't necessary if you were infected with Covid. >People who have already had confirmed covid-19 might only need a single dose of a mRNA vaccine, two small studies have indicated. Two weeks after a single dose of vaccine, people who had previously had covid-19 had antibody concentrations that were as high, or up to 10 times higher, than the levels seen in uninf…

How does that challenge this evidence?
