He proposes that it's actually molecule mutations that is the driving force something which can now easily be seen to occur in the coronavirus. When Darwin and Wallace published their new version of Evolution they proposed Natural Selection as the reason but they had no mechanism. Later discoveries provide the mechanisms -which are still evolving. Link to comment Share on other sites More sharing options...

redruby Posted March 3, 2021 Share Posted March 3, 2021 It looks promising that vaccines help reduce transmission but it is still early days. Scientists believe virus mutations are more likely if infection rates are still high in a partially vaccinated population (some people having one vaccine only and a large number still not vaccinated at all). That is one reason why I think the government are taking a gamble opening up all schools at once next week. Great as vaccines are the government are relying on them too much. We should be holding out with restrictions just a few weeks longer until infection rates are right down and more people are vaccinated. Infection rates have been falling consistently but they are still 4 times higher than they were last May when lockdown restrictions were relaxed.

petemcewan Posted March 3, 2021 Share Posted March 3, 2021 (edited) Mutation ,doesn't necessarily mean "worse". If scientists get cracking it might be possible to get the virus to mutate itself out of existence. Quote On the other hand, their mutation rates are an exploitable Achilles’ heel: researchers and clinicians can increase RNA virus mutation rates using nucleoside analogues, and a 3–5-fold increase in mutation rate causes lethal mutagenisis in human-infecting viruses like polio virus and influenza. https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3000003#pbio.3000003.ref002 Edited March 3, 2021 by petemcewan Link to comment Share on other sites More sharing options...
MuteWitness Posted March 3, 2021 Share Posted March 3, 2021 if the vaccine contained the virus would it be better against different mutations ? Link to comment Share on other sites More sharing options...
petemcewan Posted March 4, 2021 Share Posted March 4, 2021 (edited) Mutewitness. If you read the last but one paragraph. It might answer your question. https://www.newyorker.com/news/daily-comment/can-the-covid-19-vaccine-beat-the-proliferation-of-new-virus-mutations “These data highlight the prospect of reinfection with antigenically distinct variants and may foreshadow reduced efficacy of current spike-based vaccines.” mRNA vaccines can be modified quickly to address emerging variants.

The actual impact and response to the South African and other variants can be found in more 'up to date' and 'readable' sources such as : BMJ's Coronavirus (covid-19) Hub or Nature briefing(not just Covid matters) Link to comment Share on other sites More sharing options...
petemcewan Posted March 5, 2021 Share Posted March 5, 2021 (edited) Annie Bynnol Mutewitness asked a question in 4451. Live Attenuated ,Inactivated or mRNA.In your opinion ,which one of them is best at dealing with mutations ?
