1/ The largest population-based study comparing the unvaccinated/naturally immune to the vaccinated found that vaccinated people were 6 to 13 times more likely to get infected, 27 times more likely to get symptomatic infections, and 8 times more likely to be hospitalized.
2/ These findings are not surprising, since infection with the virus allows our body to form an immune response to many parts (epitopes) on the virus, whereas the vaccines expose us only to one part, the spike protein.
3/ Data from Qatar found that only 0.02% of Covid recovered individuals experienced reinfection, with no waning over time, and with reinfections less severe than initial infections.
4/ Data from the U.K. during Delta likewise found a 0.025% reinfection rate in Covid recovered people, compared to a 23% breakthrough infection rate in vaccinated people over the same time period.
