New research has found that people who have been infected with the Omicron variant show poor 'immune boosting'. Throughout the coronavirus pandemic it has been widely assumed that people gain a natural immune boost following infection. However, researchers at Imperial College London have found that Omicron provides a poor natural boost of COVID-19 immunity against re-infection with Omicron itself, even in people who are triple-vaccinated.
