The UK and California variants of coronavirus appear to have combined into a heavily mutated hybrid, sparking concern that we may be entering a new phase of the covid-19 pandemic.

Two variants of the SARS-CoV-2 coronavirus that causes covid-19 have combined their genomes to form a heavily mutated hybrid version of the virus. The “recombination” event was discovered in a virus sample in California, provoking warnings that we may be poised to enter a new phase of the pandemic.

The hybrid virus is the result of recombination of the highly transmissible B.1.1.7 variant discovered in the UK and the B.1.429 variant that originated in California and which may be responsible for a recent wave of cases in Los Angeles because it carries a mutation making it resistant to some antibodies.

A coronavirus vaccine developed by the US firm Novavax has been shown to be 89 per cent effective in preventing covid-19 in clinical trials. The trials included participants in the UK and South Africa, and found the vaccine to be 86 per cent effective against the UK variant of the virus, but only 60 per cent effective against the variant in South Africa. Novavax said it will immediately begin development on a vaccine specifically targeted to the South African variant.
