Why are so many vaccinated people getting COVID-19 lately? A couple of factors are at play.
A couple of factors are at play, starting with the emergence of the highly contagious omicron variant. Omicron is more likely to infect people, even if it doesn’t make them very sick, and its surge coincided with the holiday travel season in many places.People might mistakenly think the COVID-19 vaccines will completely block infection, but the shots are mainly designed to prevent severe illness, says Louis Mansky, a virus researcher at the University of Minnesota.
And the vaccines are still doing their job on that front, particularly for people who’ve gotten boosters.Dr. Melanie Mouzoon with Kelsey-Seybold Clinic talks about what to do if you test positive for COVID-19 and when to get tested. Two doses of the Pfizer-BioNTech or Moderna vaccines or one dose of the Johnson & Johnson vaccine still offer strong protection against serious illness from omicron. While those initial doses aren’t very good at blocking omicron infection, boosters — particularly with the Pfizer and Moderna vaccines — rev up levels of the antibodies to help fend off infection.Omicron appears to replicate much more efficiently than previous variants.
Advice for staying safe hasn’t changed. Doctors say to wear masks indoors, avoid crowds and get vaccinated and boosted. Even though the shots won’t always keep you from catching the virus, they’ll make it much more likely you stay alive and out of the hospital.
