SAGE or Public Health England should take all the approved vaccines and test them against the SA like variants. We have assumed that we have to keep the variant in check through lockdown / quarantine / testing etc until a new vaccine is developed by Oxford / Pfizer etc but what if there is another approved vaccine that functions quite well against it? I would look at the Chinese vaccines because at least one of them is a whole virus vaccine and theoretically, it should be less affected by mutations to the spike protein. There's also Novovax, to which the UK has an order, but has yet to be approved by the MHRA, which claims 60% effectiveness against the SA variant.
Why is everyone assuming we are completely reliant on one vaccine or vaccine type when there are alternatives?
