China News Service, April 1. Recently, the official website of the British government released a report on the reorganization of three new crown variants.
The data shows that there have now been 637 cases of XE in the UK (i.e. the recombination of Omicron BA.1 and BA.2).
Data map: At the Rocky Health Center in Dundee, Scotland, England, a nurse injects an 82-year-old with the new crown vaccine.
According to the website, a recombinant variant occurs when an individual is infected with two or more variants of the new coronavirus at the same time.
And this is not uncommon, with several cases of recombination of Covid-19 variants being discovered during the Covid-19 pandemic.
The UK Health Security Agency (UKHSA) analyzed 3 scenarios, namely XE, the reorganization of Omicron BA.1 and BA.2, and XD and XF for the reorganization of Delta and Omicron BA.1 .
The data shows that a total of 38 cases of XF and 637 cases of XE have been identified in the UK; no cases of XD have been identified, but 49 cases have been reported in the global database, most of them in France.
In the case of XE, UKHSA Chief Medical Adviser Professor Hopkins noted that there is not yet enough evidence to draw conclusions about its transmissibility, severity or vaccine effectiveness.
WHO Director-General Tedros Adhanom Ghebreyesus said on March 30 that existing research shows that the most likely scenario is that the new coronavirus will continue to evolve, but as human immunity increases due to vaccination or infection, the new coronavirus will continue to evolve. The severity of the resulting disease decreases over time.
