A new study by the University of Washington has found that people who got infected with Covid-19 during the early stages of the pandemic got re-infected when the omicron variant swept the world. The findings of the meta-analysis of 65 studies from 19 countries showed that people infected with alpha, beta, and delta variants were only 36% better protected from reinfection with omicron. However, such patients were able to avoid hospitalization with omicron, and death, almost 90% of the time over the same period. The research may help health officials steer vaccination campaigns and form policy recommendations. Vaccinations are the best way to gain protection from the virus, particularly for people who are older or who have other health conditions. The study highlighted that the Covid infection gives similar immunity to vaccination, and that the protection against Covid-19 from being previously infected lasts at least as long as that offered by vaccination.
