From BBC (1/25/21): Moderna vaccine appears to work against variants
“For the Moderna study, researchers looked at blood samples taken from eight people who had received the recommended two doses of the Moderna vaccine. The findings are yet to be peer reviewed, but suggest immunity from the vaccine recognises the new variants. Neutralising antibodies, made by the body’s immune system, stop the virus from entering cells.
Blood samples exposed to the new variants appeared to have sufficient antibodies to achieve this neutralising effect, although it was not as strong for the South Africa variant as for the UK one. Moderna says this could mean that protection against the South Africa variant might disappear more quickly.”
