A lot of Canadians are genuinely concerned about the possibility of having to deal with the South African variant. My understanding is that it's going to be fairly easy to adapt the current vaccines in order for them to be effective against the South African variant. Some companies, I think of both Moderna and Novavax, are already in the process of doing that in testing these tweaks.
With these tweaks, will the vaccines have to go through the whole regulatory process again, i.e. phase one, phase two and phase three trials to be approved, or will it be quicker?
