  • Some scientists worry that coronavirus vaccines will not be as effective against the UK mutation (version B.1.1.7) that caused quite a stir over the weekend.
  • The UK coronavirus mutation has been spreading rapidly in Great Britain and might be more infectious than its predecessors — but there’s no evidence it can cause more severe COVID-19 or evade vaccines.
  • Some experts think the vaccines might be less effective against this strain, saying that more tests are required before we know for certain.

British prime minister Boris Johnson’s announcement that the UK coronavirus mutation might be spreading more rapidly than its predecessors sent shockwaves through the world. Just days before Johnson’s revelation that stricter measures will be employed in the UK over the Christmas holidays, UK health officials disclosed the new SARS-CoV-2 strain. They said they’ve been following B.1.1.7 since September, and the virus mutation seems to be more infectious. It’s not causing a more severe version of COVID-19, but it spreads faster than other known strains. Many European countries closed their borders with the UK, even though the mutation was already found in the Netherlands and elsewhere.

Health experts like Dr. Anthony Fauci and others called for more data, asking the world not to overreact to the news. Fauci himself said travel to and from the UK should not be banned, but other precautions can be used, like testing of travelers. Vaccine makers including Pfizer and Moderna have said their newly approved drugs are highly likely to work against the new strain, although more tests are required before we know for sure. Now, some geneticists are worried that the vaccines might not work as well against the B.1.1.7 strain as they do on the more prevalent SARS-CoV-2 strains.
