Results
Overall, 673,676 MHS members 16 years and older were eligible for the study group of fully vaccinated SARS-CoV-2-naïve individuals; 62,883 were eligible for the study group of unvaccinated previously infected individuals and 42,099 individuals were eligible for the study group of previously infected and single-dose vaccinees.
Model 1 – previously infected vs. vaccinated individuals, with matching for time of first event
In model 1, we matched 16,215 persons in each group. Overall, demographic characteristics were similar between the groups, with some differences in their comorbidity profile (Table 1a).

During the follow-up period, 257 cases of SARS-CoV-2 infection were recorded, of which 238 occurred in the vaccinated group (breakthrough infections) and 19 in the previously infected group (reinfections). After adjusting for comorbidities, we found a statistically significant 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection as opposed to reinfection (P<0.001). Apart from age ≥60 years, there was no statistical evidence that any of the assessed comorbidities significantly affected the risk of an infection during the follow-up period (Table 2a). As for symptomatic SARS-COV-2 infections during the follow-up period, 199 cases were recorded, 191 of which were in the vaccinated group and 8 in the previously infected group. Symptoms for all analyses were recorded in the central database within 5 days of the positive RT-PCR test for 90% of the patients, and included chiefly fever, cough, breathing difficulties, diarrhea, loss of taste or smell, myalgia, weakness, headache and sore throat. After adjusting for comorbidities, we found a 27.02-fold risk (95% CI, 12.7 to 57.5) for symptomatic breakthrough infection as opposed to symptomatic reinfection (P<0.001) (Table 2b). None of the covariates were significant, except for age ≥60 years.
Nine cases of COVID-19-related hospitalizations were recorded, 8 of which were in the vaccinated group and 1 in the previously infected group (Table S1). No COVID-19-related deaths were recorded in our cohorts.
Why is it that anti-vaxxers claim vaccines are unsafe despite every study imaginable telling them otherwise because "only time will tell" and the future is "unknowable", yet they claim that natural immunity is safer for us in the long term because a study tells us that? Why is it that the future is knowable to them only if they think it supports their narrative, but is not when it doesn't?
Regardless, this study is a perfect example of the lengths to which anti-vaxxers will go to misrepresent what something means, or they're just too stupid to understand what a study does and doesn't mean. Yes, those with natural immunity have longer lasting protection against infection, just like pretty much everyone who develops natural immunity from an illness that doesn't kill them, like polio and smallpox had stronger immunity than a vaccine could provide. Do you see where this is going?
The other thing about this study is that it compares people who got vaccinated with a sample of those who got Covid, excluding the approximately 700,000 unvaccinated people who have died from it plus all the others who have suffered debilitating long term complications. I guess we don't need seatbelts, because if you exclude all the people who died not wearing them, no one dies from not wearing seatbelts. I guess we don't need penicillin because if you just exclude all the people who die from infections because they did not take penicillin, no one dies from infections.
None of this changes the unquestionable conclusion that acquired immunity through vaccination is safer overall than natural immunity. If you get vaccinated, it is much less likely you will get Covid than if you aren't, and there is virtually a 0% chance that you will get seriously ill let alone die from Covid. If you rely on natural immunity, however, you'll only be in much better shape unless it kills you or you become seriously ill from it of course. Natural immunity has a 100% chance of saving your life if you aren't like one of the approximately 700,000 so far for whom it didn't work at all. And if you're vaccinated, you are a much lower risk to transmit it to someone else, whereas if you rely on "natural immunity", you only become a reduced risk to transmit it to others after you've already given it to everyone around you when you got it.
