Finland detects UK & SA variants. As immune pressure on virus grows, evolution will speed up & any variants that escape that immunity will have selective advantage. Both variants huge worry, variant described SA, may already evade mAbs, variant UK more transmissible
Making Tests,Treatments,Vaccines available globally is a moral imperative. It is a scientific imperative.If not variants that may escape immune control via infection/vaccination that arise in one part world will reverberate everywhere. Truly no one is safe until we are all safe
World is playing with fire, & does not control the evolutionary path of a virus circulating at this level & under this pressure globally. 2021 may be less predictable than 2020. Is in our hands reduce transmission,use all tools equitably & as an urgent public heath imperative.
Mutations in receptor binding domain (RBD) in S Africa described variant a massive wakeup call on just how plastic Spike RBD can be. All vaccines & mAb treatments target this single protein.
This pandemic is not over, having vaccines & treatments only helpful if available to all & used urgently and before further evolution & evasion of protective immunity. Also critical that work on second generation treatments & vaccines progresses urgently.
And that needs to be funded. The ACT-A is still scrabbling around for the money to do the R&D, Manufacturing & Distribution. Have to speed up availability Tests, Treatments, Vaccines, Oxygen, PPE, - globally.
Plus invest second generation vaccines/treatments. Not impossible to imagine interventions only targeting Spike Protein rendered much less effective in months/years to come. Variants driving increased transmission & possible immune escape already circulating. Will not be the last
