“It’s very unlikely that the current vaccine won’t be effective on the variants whether in Kent or other variants especially when it comes to severe illness and hospitalization,” Vaccine Deployment Minister Nadhim Zahawi told Sky.
“All manufacturers, Pfizer-Biontech, Moderna, Oxford-AstraZeneca and others are looking at how they can improve their vaccine to make sure that we are ready for any variant - there are about 4,000 variants around the world of COVID-19 now.”
