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

Firstpost  

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. 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. 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. Vaccinated people who get the virus are more likely to have mild symptoms, if any, since the shots trigger multiple defenses in your immune system, making it much more difficult for omicron to slip past them all.
