Why are so many vaccinated people getting COVID-19 lately?

There are a few factors at play, starting with the emergence of the highly contagious variant of omicron. Omicron is more likely to infect people, even if it doesn’t make them very sick, and its surge has coincided with the holiday season in many places.

People might mistakenly think that COVID-19 vaccines will block infection completely, but the injections are primarily designed to prevent serious illness, says Louis Mansky, a virus researcher at the University of Minnesota.

And vaccines are still doing their job on that front, especially for people who have received boosters.

Two doses of Pfizer-BioNTech or Moderna vaccines or one dose of Johnson & Johnson vaccine still provide strong protection against serious illnesses caused by omicron. While these initial doses are not very effective in blocking omicron infection, boosters – especially with Pfizer and Moderna vaccines – increase antibody levels to help fend off infection.

Omicron appears to replicate much more efficiently than previous variants. And if those infected have a high viral load, they are more likely to pass it on to others, especially those who are not vaccinated. Vaccinated people who contract the virus are more likely to have mild symptoms, if any, because the injections trigger multiple defenses in your immune system, making it much harder for omicron to get past them all.

The tips for staying safe have not changed. Doctors say to wear masks indoors, to avoid crowds, and to get vaccinated and boosted. Although the injections will not always prevent you from catching the virus, they will greatly increase the likelihood that you will stay alive and out of the hospital.
