COVID-19: Moderna to test out jab against South African variant

Vaccine manufacturer Moderna is to test out a jab against the South African variant of the virus that causes COVID-19. The company made the decision after laboratory tests showed a six-fold reduction in the ability of antibodies, produced in response to the vaccine, to kill the new version of the virus. The UK has 17 million doses of Moderna's vaccine on order, with deliveries due to start in the spring.
