Ómicron has a high capacity to circumvent natural antibodies generated by a previous covid-19 infection, while vaccinated people show much greater resistance, according to a joint study by the University of Geneva and the University Hospital of this same city.

Another important finding of the study is that omicron’s ability to cause hospitalizations and deaths is greatly reduced when it comes to people who have been vaccinated against covid-19.
