Francis Crick Institute in London says area of spike protein of Sars-CoV-2 could form basis of jab against variants and common cold

Scientists have made a “promising” advance towards developing a universal coronavirus vaccine to tackle Covid-19 and the common cold.

Researchers at the Francis Crick Institute in London have discovered that a specific area of the spike protein of Sars-CoV-2 – the virus that causes Covid-19 – is a good target for a pan-coronavirus jab that could offer protection against all the Covid-19 variants and common colds.

Developing a vaccine that protects against a number of different coronaviruses is a huge challenge, they said, because this family of viruses have many key differences, frequently mutate and generally induce incomplete protection against reinfection. That is why people can repeatedly catch common colds, and why it is possible to be infected multiple times with different variants of Sars-CoV-2.
