"Covid-19: Pfizer study suggests vaccine works against new UK virus strain"

New research was done on the Pfizer vaccine COVID-19 vaccine can protect against a mutation found in two contagious variants of the coronavirus that erupted in Britain and South Africa.Most of the vaccines being rolled out around the world train the body to recognise that spike protein and fight it. Researchers with Pfizer's team from the university of Texas Medical Branch in Galveston for laboratory tests to see if the mutation affected its vaccine's ability to do so.They used blood samples from 20 people who received the vaccine, made by Pfizer and its German partner BioNTech, during a large study of the shots. Dr Philip Dormitzer Pfizer chief scientific officer said that "it was a very reassuring finding that at least this mutation, which was one of the ones people are most concerned about, does not seem to be a problem”. Viruses constantly undergo minor changes as they spread from person to person Scientists have used these slight modifications to track how the coronavirus has moved around the globe since it was first detected in China about a year ago. Dormitzer said if the virus eventually mutates enough that the vaccine needs adjusting – much like flu shots are adjusted most years – that tweaking the recipe wouldn't be difficult for his company's shot and similar ones he also said that “of ongoing monitoring of virus changes to see if any of them might impact on vaccine coverage.”
