Mr Argar informed BBC Breakfast that each examine “deserves to be taken very severely” however there was “no proof” that the Oxford-AstraZeneca vaccine was not efficient at stopping extreme sickness from coronavirus “which is the important thing factor we’re looking for to deal with”.
South Africa’s suspension of the rollout of the vaccine was solely “momentary” at this stage and the “context is a bit bit totally different” to the UK the place the Kent variant is the dominant pressure, he stated.

Progress shall be incremental. However vaccines are nonetheless the best way out of this.
