The people best protected against Covid-19 are those who have both been vaccinated and infected, show two studies published Friday April 1 in the Lancet Infectious Diseases.
If you have been vaccinated but also contracted Covid-19, you should have a better immune response. This is revealed by two works published in the Lancet Infectious Diseases. These studies underline that a former Covid patient has every interest in being vaccinated to strengthen the immunity already acquired by his past infection.

The second study, carried out using Swedish data, goes in the same direction. She shows that former Covid patients maintain high immunity for up to twenty months. But, it also indicates that these people see the risk of reinfection drop even more – by two thirds, approximately – if they were vaccinated after their first infection. These two studies suggest that “hybrid immunity, acquired by being exposed to both infection and vaccination, (…) could give long-lasting protection, including against new variants”concludes the Indian researcher Pramod Kumar, who did not participate in these studies.
