In a study of over 300,000 adults, those with natural covid immunity fared better than the vaccinated did.
I know, shocker of all shockers, the naturally immune fared better than the vaccinated did during delta and omicron.
What is great about this study is that it evaluated over 300,000 adults who were either non vaccinated, vaccinated, previous covid infection or none. What they found was that the vaccinated cohort was 5.5 times more likely to catch delta than the non vaccinated, and 1.1 times more likely to catch omicron than the non vaccinated.
Additionally, the vaccinated were 7 times more likely to be hospitalized during the delta wave and were 2 times more likely to be hospitalized during omicron.
“In the cohort comparing the naturally immune to people without prior immunity or vaccination, researchers found that the naturally immune were much better protected against hospitalization, used as a measure of protection against severe disease. During both periods, natural immunity proved to be highly effective in protecting against reinfections progressing to severe disease and was associated with a significantly lower risk of COVID hospitalization than no SARS-CoV-2-specific immunity," the researchers said.
“But they also discovered that the naturally immune, while much less likely to be infected during the Delta era, were actually more likely to test positive during the Omicron era.” This is interesting because it lines up with most unvaccinated people that I personally and professionally know. Most of the unvaccinated people I know that caught covid did so during the omicron era in December 2021-March 2022. That is when both my husband and I caught “covid”. Antibody testing via blood draw was how we knew what we were sick with. Our SARS antibodies were extremely high 6 weeks post infection.
Side note to all of this: there is a possibility that my husband and I both had “covid” in the spring of 2020. Shortly before lockdown, I got sick. And 3 days later my husband got sick. That round of illness was unlike anything we had ever had before. My husband got winded going up and down our stairs. I had so much pressure in my head I felt like it was going to explode. Neither of us ran a fever. Both of us had horrible sinus congestion and fatigue that took about a month to get over. So it is possible we caught the “coof” early on, build antibodies to it, and then had a second round with omicron. Because we had zero colds/flu/illness at all from March 2020 until January 2022. There is no way to know for sure, we did the original “covid antibody” test that everyone was running to get in the spring of 2020, and my husbands came back negative, mine came back positive and then they called me later that evening to say they had told me wrong and it was negative. With a 30% failure rate, it is hard to know if that antibody test was accurate in reading our results anyways. My husband was much sicker with Omicron than I was as well. Just some anecdotal info.
