Past COVID infection 'as good as vaccines' at preventing severe illness

While the research suggests that natural immunity could be just as good as vaccines at preventing serious illness from COVID-19 infection, the study's authors encourage people to still get vaccinated, to avoid any complications from any initial infections.

The study’s summary reads, “Protection against severe disease remained high for all variants, with 90·2% (69·7–97·5) for ancestral, alpha, and delta variants, and 88·9% (84·7–90·9) for omicron BA.1 at 40 weeks.”


Figures from the study show that previous infection was significantly more protective in all aspects of protection against all variants, for a substantially longer period of time than vaccination.


The most profound and important graphic is the comparison for Omicron immunization.
Against the currently dominant variant, past infection thoroughly outperformed Moderna and Pfizer’s mRNA vaccination in both re-infection and symptomatic disease.
