[Epoch Times on January 4, 2022](Epoch Times reporter Da Furuo compiled a report) According to a study published last week in Denmark, the Omicron variants of the Chinese communis The immunity of the vaccinated population, this finding helps explain why Omicron spreads faster.
Since the severely mutated Omicron variant was discovered in November last year, scientists have been studying whether it can cause the less severe COVID-19 disease and why it is more infectious than the previously dominant Delta variant.
A virus may be more spread for many reasons, such as how long it stays in the air, its ability to attach to cells, or its ability to evade the body’s immune system.
In mid-December, Danish scientists surveyed nearly 12,000 households and found that among the vaccinated Danes, Omicron was 2.7 to 3.7 times more infectious than the Delta variant.
This study conducted by researchers from the University of Copenhagen, the Danish Statistics Agency, and the Danish National Serum Institute (Statens Serum Institut, referred to as SSI) showed that the main spread of the Omicron variant virus is faster because it is better at evading vaccines. Immunity.
The researchers said: “Our results confirm that the rapid spread of Omicron (variant) is mainly attributable to immune evasion rather than inherent growth in basic infectiousness.” The study has not been peer-reviewed.
78% of Danes have been fully vaccinated, and nearly 48% of them have received a third dose of the “booster” vaccine. More than 8 out of 10 Danes were vaccinated with Pfizer’s BioNTech vaccine.
The study also found that people who received booster vaccines were less likely to transmit the virus than people who were not vaccinated, regardless of the variant.
Tyra Grove Krause, the technical director of the Danish National Serum Institute, told local media on Monday (January 3) that although the Omicron variant is more easily spread, it does not seem to cause serious problems. Disease.
“Although Omicron is still able to put pressure on our healthcare system, everything shows that it is milder than the Delta variant.” She said, adding that the risk of Omicron’s hospitalization is half that of Delta.
This echoes the results of other studies on Omicron.
Data from Denmark shows that of the 93 people admitted to Omicron in late December, fewer than 5 are in intensive care.
