The British government on the 16th to Wuhan pneumonia (new coronavirus disease, COVID-19) “Beta” variant of the virus strain, continued to spread in France, on the grounds that the French entrants ruled out the loosening of vaccination. British epidemiologists have pointed out that the Beta strain is apparently more immune to vaccines, especially the Oxford-AstraZeneca vaccine, than the current mainstream Delta strain.
The Beta variant was first identified in South Africa and is listed with the Delta strain as a World Health Organization (WHO) Variants of Concern (VOC) for new coronaviruses. According to GISAID, a global shared data repository, about 3.4% of infections in France in the past four weeks were with the Beta strain.
John Edmunds, a member of the British government’s Scientific Advisory Group on Emergencies (Sage) and professor of epidemiology at the London School of Hygiene and Tropical Medicine, told the station’s “Today” program that “the Beta strain is still a threat,” BBC News 17 reported. strain is still a threat, it may be less infectious than the Delta strain that is spreading in the UK at the moment, but it has the advantage that it is apparently better able to evade the immune response from the vaccine” and “there is credible evidence from South Africa that Beta is more effective at evading the immune response from the AstraZeneca vaccine. “
Edmonds noted that the U.K. Department of Health was right to be concerned about the Beta strain, and that as the vaccine makes more people immune, “conditions are right” for the Beta variant to become more advantageous.
The UK has lifted immunization restrictions since 19, and adults entering from “yellow list” countries no longer need to be quarantined for 10 days if they are fully vaccinated, but the Department of Health said that due to the “ongoing” cases of Beta variant strains in France, those entering from France will not be eligible for the relaxed restrictions. However, the Department of Health said that due to the “continued” cases of the Beta variant in France, the relaxed rules do not apply to those entering from France, and those who have been in France for 10 days prior to entry must still be quarantined at home after entering the UK.
