Mutations present in the variant are predicted to dramaticallyreducethe ability of certain synthetic antibodies to bind the virus, although experimental tests are needed to confirm this. whether and at what concentration sera from vaccinated people and from convalescent patients can neutralize omicron or a mock virus with a similar set of mutations. We have always known antigen tests have lower sensitivity than molecular tests. Rapid antigen tests are not as accurate as PCRs, which are handled in a lab, but they have several advantages: they are faster, cheaper, can be done at home and have proven sufficiently sensitive when the person has a higher viral load and is therefore more contagious (although the spread of the omicron variant is complicating this picture). hat have vaccine manufacturers said about the need and timeline for omicron-specific vaccines?
