The “hybrid immunity” against Covid-19, developed by having the disease and vaccination, remains at very high levels even after a year, a study by the World Health Organization (WHO) reveals this Thursday.
The research, published this Thursday in the journal The Lancet Infectious Diseases, concludes that this hybrid immunity offers greater protection than that developed by the simple passage of the disease.
In this way, the idea that it is advisable to get vaccinated even after having been infected with Covid-19 is reinforced, highlights the WHO study in collaboration with Unity Studies and SeroTracker.
The study, based on data from 26 investigations, indicates that after one year of hybrid immunity, a patient is 95% less likely to develop severe forms of the disease that require hospitalization.
The percentage drops to 75% with the simple immunity of unvaccinated formerly infected with Covid-19.
Protection against reinfection by Covid-19 is lower in both cases, but here too hybrid immunity has advantages, since the chances of getting sick again drop by 42%, while for those who have not been vaccinated it drops by only one. 25% .
Covid-19 has been considered an international public health emergency since January 30, 2020 and a pandemic since March 11 of the same year.
