(CNN) – A new study of proportional evidence suggests that a vaccine against covid-19 may be effective against new variants of coronavirus first identified in South Africa and the United Kingdom, pending a preemptive mutation.
The viruses contain a known mutation such as N501Y. Scientists are preoccupied with allowing this virus to elute the immunological protection generated by a vaccine.
The researchers create in the laboratory a version of the virus with the variant. It will be taken with extra blood from 20 people who have received doses of the Pfizer vaccine as part of a clinical trial. In an investigation published online the Jews, it appears that we will not find “any reduction in the activity of neutralization” against the mutated virus.
The N501Y mutation appears to help the virus adhere to human cells, which can be explained by the fact that these new cephalopods are more transmissible. Pero is only one of the many mutations in both cases that scientists anticipate that the virus may be less susceptible to vacancies or treatments.
Missing more research on variant
The study, conducted by researchers from Pfizer and the University of Texas Medical Center, does not test the full range of these mutations. Tampoco has been revised by pares.
In a statement last month, Pfizer said it had conducted similar tests in “multiple multiple cases. Hasta la fecha, hemos encadra una cobertura constante de todas las cepas probadas ».
It will be important to continue “monitoring the importance of the changes in the coverage of the vacancy”, the investigators will write.
If so, there is no doubt that “the possibility of a future change … may require a change of cage”. So many Pfizer vacancies as Modern use genetic technology that allow vacancies to adapt rapidly to keep up with the changes, anotaron.
