COVID-19 Vaccine Approval and Herd Immunity: Key Insights

Strategic Insights -

The approval of the Oxford-AstraZeneca vaccine is being hailed as a game-changer in the fight against COVID-19, with its ability to be stored at easily managed temperatures and generate both antibodies and hunter-killer T cells that protect against infection and treat disease. Respiratory disease expert Professor Calum Semple has praised the vaccine, highlighting its effectiveness in creating T cells that can help people who have been infected and prevent further disease. However, the path to herd immunity is expected to take several months, with vaccination programmes only just beginning and predicted to reach herd immunity by next summer.
