Danish study: Omicron evades the immune system

A recent Danish study said that the Omicron mutant of the Corona virus is better than the Delta mutant at evading the immunity of vaccine recipients, which helps explain why the Omicron spreads more quickly.

Since the discovery of Omicron last November, scientists have been racing to determine whether it causes a less severe form of the disease and why it is more contagious than the delta mutant that was prevalent before it.

The reasons for the virus’s ability to spread infection more than others are multiple, such as the length of time during which it remains in the air, its ability to stick to cells or evade the immune system in the human body.

Through the study, which included nearly 12,000 homes in Denmark in mid-December, scientists concluded that Omicron is 2.7 to 3.7 times more capable of infection than the delta mutant among the Danish people who receive the vaccine.

The study, conducted by researchers at the Institute of Statistics at the University of Copenhagen, suggests that the omicron virus spreads more quickly primarily because it is better than the delta mutant at evading vaccine-acquired immunity.

And 78 percent of Danes received the full vaccine, while nearly 48 percent received a third booster dose.

The study also found that the chances of those receiving a booster dose transmitting the virus to others, regardless of the strain, are lower, compared to those without the booster dose.
