British researchers say there is growing evidence that the full two courses of existing vaccines will “clobber” the more transmissible strains of COVID-19 - a development that could help unlock international travel and help relieve millions from lockdowns.
“There’s been some more reassuring data showing that once you’ve had the second dose it really clobbers all the variants, we just need time to show that,” Professor Spector said.Credit:Ellie Barnes, a Professor in Hepatology and Experimental Medicine at Oxford University and member of the UK Coronavirus Immunology Consortium, said there was data showing the jab worked well against the South African variant, but only after the second dose.
“After you give the second dose you get really robust neutralisation of the South African variant, so I think we can be reassured of that.“And even after a single dose the data from these vaccines in South Africa itself shows a single dose prevents you from hospitalisation and severe infection.Professor Barnes said the same outcome was likely against the Brazilian variant, which is similar to the strain that emerged in South Africa.
