Covid-19 Coronavirus Variants -- News Updates January 19, 2021
At least three major coronavirus variants have been spotted in Britain in recent months – from Kent, South Africa and Brazil – and they appear to be evolving to spread faster and to evade some parts of the immune system, although scientists do not yet think any have yet got so far as to slip past the vaccines completely
* EXCLUSIVE: Professor Ravi Gupta warned new variants are 'a signal' to act
* He said mutations on the virus will start 'chipping away' at vaccine effectiveness
* Current vaccines will still work on Covid variants but may not work forever
* Experts have found reduced immune responses to variants in survivors' blood
Scientists need to start developing new Covid vaccines now to stop the coronavirus evolving to escape the immune system, an expert investigating new variants of the virus has warned.
Professor Ravi Gupta, a Cambridge University microbiologist, fears there is a risk that mutations will 'chip away' at the efficacy of the current crop of vaccines as they build up.
The vaccines we have now should work against the current virus, he said, but they should be kept updated with new variants in case it mutates so much that they stop working.
