This Week in Science: Omicron variant, brain swelling linked to Alzheimer's medication, lyme disease vaccine, CDC recommendation for universal boosters
By Sophie Wax, Cindy Zhang and Maiah Islam | December 2A new COVID-19 variant labeled omicron has recently emerged in several countries, including South Africa, Botswana and Hong Kong, and contains dozens of mutations from the original alpha variant,leading many scientists to discuss its implications for COVID-19’s future. Although the moment when omicron first started to infect people is not exactly known, infectious disease researcher Kristian Andersen hypothesizes that the variant could have emerged in September or October, indicating that it was initially slow to spread. However, this does not mean that it is less contagious than previous variants; in fact, researchers predict that the mutations associated with omicron may likely increase the virus’s resistance to the vaccine and its rate of infection, according to evolutionary biologist Jesse Bloom. Because of this,researchers are suggesting that people receive a booster shot to strengthen their protection against omicron.
