Omicron circumvents mRNA booster protection, South African studies show


According to a South African study, the new coronavirus omicron variant can circumvent the protection provided by messenger RNA (mRNA) COVID-19 vaccines such as Pfizer and Modana.

Study published on Tuesday Lancet We examined some of the first recorded breakthrough cases of highly contagious Omicron strains in South Africa in late October.

From late November to early December, a group of seven Germans who received three vaccinations, including at least two vaccinations with the mRNA vaccine, visited Cape Town and subsequently experienced symptomatic COVID-19. ..

No one reported a history of COVID-19 infection. COVID-19 is a disease caused by the CCP (Chinese Communist Party) virus.

The case within the group was the first recorded breakthrough infection with an Omicron variant in a fully vaccinated individual after receiving an additional vaccine, the study said.

“The presence of this group from Germany provided a unique opportunity to study Omicron breakthrough infections in individuals with mRNA vaccine boosters,” the researchers said.

The authors stated that their findings were limited to “a small number of relatively young and otherwise healthy individuals.”

“This case series adds, as expected, additional evidence that Omicron can circumvent the mRNA-induced immunity in vivo,” the researchers said.

They also said their findings emphasize the importance of adopting measures to control the spread of the virus, such as social distance and wearing masks.

The COVID-19 vaccine was initially overwhelmed as a way to prevent infection with the CCP virus. Authorities wanted to get herd immunity by getting enough vaccines. In this situation, the virus is significantly reduced or eliminated.

Even before the emergence of the Omicron strain, these hopes did not spread, mainly because the vaccine proved to be increasingly ineffective in preventing infection.

Meanwhile, a World Health Organization (WHO) official said Tuesday that new variants of the new coronavirus are likely to emerge given the current high levels of infection.

Maria Van Kerkhove, WHO’s Technical Lead Officer for COVID-19, said at a briefing in Geneva that the Omicron variant could be the last strain as the virus is still “circulating at very intense levels” around the world. He said the sex was low.

“I’ve heard that many suggest that Omicron was the last variant and that it’s over after this, and that’s not the case,” she said.

Van Kerkhove said that measures to control the infection of the virus need to be continued to reduce serious illness and death, such as wearing masks, increasing social distance and avoiding crowded areas. rice field.

Dr. Anthony Fauci, President’s chief medical adviser to President Joe Biden, said on Monday that research efforts should now focus on the COVID-19 vaccine, which can provide broad protection against new strains.

“We don’t want to get caught up in the mole slap of all the variants that need to create boosters for a particular variant,” he said. “You will chase it forever.”
