Coronaviruses are coronaviruses. They invade cells by using a spike protein to latch on to other cells. If they do not have this spike protein then they are not coronaviruses. The Pfizer, Moderna and Oxford/AstraZeneca vaccine all target this spike protein. Any other mutation within the virus will involve proteins that don’t really alter the viruses main route into a cell. For that reason, most vaccines will be effective against ALL strains of coronavirus, it’s just a question of how effective.
Again, these are things witnessed every day in life by microbiologists, it’s just that right now they are dealing with a virus that is transmitting across the globe and any mutation or variant of it is headline news.
Brilliant summary Gary, thank you.
