Vaccines and Immunity: Is Omicron the last threat?

Wednesday, March 2, 2022


SARS-CoV-2 variations are keeping us on our toes in our fight against COVID-19. WHO announced in late November that there is a Variant of Concern (VOC), Omicron, with 32 mutations in the spike protein. This is about double that of the Delta strain, which is currently dominating COVID-19 infections around the world. This new VOC is expected to be more transmissible and infectious than the Delta strain. How quickly and widely would Omicron spread? Would it dominate the other variants? Would this new variant reduce vaccine effectiveness? In this webinar, we will discuss the recent developments in our fight against COVID-19 and changes in vaccination programmes to effectively combat Omicron.
