Are New Omicron Subvariants a Threat?

Are New Omicron Subvariants a Threat?

This past December and January, the world was stunned at the astonishing transmissibility of the Omicron variant of SARS-CoV-2. Tulio de Oliveira and the team that first discovered it in South Africa are now back with new analysis of two Omicron subvariants that may evade current immunity and vaccination - BA.4 and BA.5. A frightening prospect, to be sure, but further epidemiological research is needed to better understand the severity of disease it could cause in humans.

But caution abounds in new COVID-19 research: “...researchers are grappling with how to openly communicate their concerns and the uncertainty about variants while not provoking unnecessary government policies and anxiety.” South Africa has experienced this pain - travel bans not only added excessive burden to the country’s economy after news broke about Omicron, they also did little to prevent the spread of disease.
