Virologist explains why so many vaccinated people fall ill with COVID-19

University of Minnesota virologist Louis Mansky explained why so many fully vaccinated people have contracted coronavirus lately. Several factors come into play, he says, starting with the emergence of the highly contagious omicron variant.

The new variant of covid is much more contagious than previous strains, even if they do not cause serious illness in them. At the same time, the outbreak of COVID-19 in many territories coincided with the holiday travel season. People may mistakenly believe that COVID-19 vaccines completely block the infection, but vaccines are mainly designed to prevent serious illness, the virologist notes.

Omicron reproduces much more efficiently than previous versions. And if infected people have a high viral load, they are more likely to transmit the virus to others, especially the unvaccinated. Vaccinated people who contract the virus are more likely to have mild symptoms because the vaccines trigger several defense mechanisms in the immune system.

To reduce the chance of contracting the coronavirus, doctors advise wearing masks indoors, avoiding crowds, and getting vaccinated and revaccinated. According to Luis Mansky, despite the fact that vaccinations do not always save you from contracting the virus, they increase the likelihood that a person will survive and not go to the hospital.
