Currently, as you know, the manufacturers are including different variants in their vaccines. In the next few months, we may see different variants included. They're looking at the original strain, the wild-type strain, and potentially the omicron strain. That's the nearest strategy.
As mentioned, we're also looking at other types of vaccines. Mucosal vaccines, which are delivered in the nose or in the mouth, will potentially enhance the vaccine protection that we get from an injectable vaccine and provide more protection against infections.
This research is all ongoing. We need to take each wave as it comes and the epidemiology as it comes to see what products are available. NACI will then make its recommendations, keeping all of that information in mind.
