Omicron Variant Is Better At Evading Immunity And Is More Contagious Than Delta Variant

According to a Danish study published last week, the Omicron coronavirus variant is stronger at evading vaccinated people’s protection than the Delta variant, which may explain why Omicron is spreading faster.

Scientists have been scrambling to figure out whether the extensively mutated Omicron variant produces less serious disease and why it appears to be more contagious than the previously dominant Delta variant since its discovery in November.

A virus’s transmissibility can be increased for a number of reasons, including the length of time it remains in the air, its capacity to hook onto cells, or its ability to evade the body’s immune system.

In mid-December, scientists looked into roughly 12,000 Danish households and revealed that Omicron was 2.7 to 3.7 times more infectious than the Delta variant amongst vaccinated Danes.

Researchers from the University of Copenhagen, Statistics Denmark, and Statens Serum Institut (SSI) believe the virus spreads more quickly because it is stronger at resisting vaccine-induced protection.

Our findings confirm that the rapid spread of the Omicron (variant) primarily can be ascribed to the immune evasiveness rather than an inherent increase in the basic transmissibility," the researchers said. The study has yet to be peer-reviewed.

Seventy-eight percent of Danes have had all of their vaccinations, with roughly 48 percent receiving a third “boosted" dose. Pfizer-vaccination BioNTech’s has been given to more than eight out of ten Danes.

The research also found that booster-vaccinated individuals are less inclined to spread the virus than unvaccinated people, regardless of the variant.

SSI’s technical director, Tyra Grove Krause, told local media on Monday that while the Omicron variant is more transmissible, it appears to cause less serious disease.

While Omicron will still be able to put pressure on our healthcare system, everything indicates that it is milder than the Delta variant," she said, adding the risk of being hospitalised with Omicron was half of that with Delta.

This is consistent with the findings of other Omicron research.

According to Danish data, less than five people were getting intensive care out of a total of 93 individuals hospitalised to hospitals due to COVID-19 from Omicron in late December.

This may be what is going to lift us out of the pandemic so that this becomes the last wave of the corona," Krause said.
