Pfizer sees ’40-fold reduction in antibodies’ against omicron but still offers some protection – study – .


Omicron more transmissible but softer than delta variant, according to early research

Pfizer’s vaccine offers some protection against the new omicron variant, but it was able to partially escape it, according to an early study from South Africa.

Researchers at the Africa Health Research Institute in Durban conducted the first experiment to assess the effectiveness of the Pfizer vaccine on omicron and found that it resulted in an approximately 40-fold reduction in the levels of neutralizing antibodies produced by people who had received two doses of Pfizer. -BioNTech SE shot, compared to the variant detected in China almost two years ago.

Research has also found that a third dose can enhance the vaccine’s protection against the highly mutated variant.

Meanwhile, America’s leading infectious disease expert, Dr Anthony Fauci, said the omicron variant was “clearly highly transmissible,” but “almost certainly” was no more severe than delta.

New leaked images on Tuesday appear to show Downing Street staff joking around last Christmas while preparing a proper response to potential questions about whether a No 10 party broke Boris Johnson’s own coronavirus rules .

In a recording obtained by ITV News, which was reportedly made on December 22, former Downing Street press secretary Allegra Stratton can be seen laughing and saying: “This fictional party was a business meeting and it was not being left behind. socially ”, while reminding colleagues:“ This is recorded ”.

Australia finds new ‘omicron-like’ subline

Australian Queensland has detected two new cases of omicron, including one with a different lineage from the new variant.
While Australia has already confirmed cases of community transmission of omicron, the two cases are the first for Queensland.
Two men, who traveled from Nigeria and South Africa, were found infected with the omicron variant and both were isolated while their contacts are tested, officials confirmed on Wednesday.
But samples from one of those tested, who traveled from South Africa to Brisbane on Saturday, were found to have a slightly different lineage of omicron genetically.
The scientific team that spotted the difference forwarded it to the international committee, which resulted in the reclassification of the variant into two lineages.
“The important part is these two sublines, one has the dropped S gene and is the normal way of omicron screening … but that other gene then doesn’t have that dropped S gene,” said Peter Aitken , Queensland Director of Health. cited by ABC Australia.
He added that a new classification would make it easier for people to recognize the potential spread of omicron in all communities.

Fauci says omicron Covid variant ‘almost certainly’ is no more serious than Delta

The top infectious disease official in the United States has said the omicron coronavirus variant is “clearly highly transmissible” but “almost certainly” is no more serious than delta.
Speaking to Agence France-Presse, Dr Anthony Fauci said experiments testing the potency of antibodies from different vaccines against the omicron variant should be available in “a few days to a week”.

Existing vaccines should be able to protect against omicron, WHO official says

Reacting to the first lab tests in South Africa showing Pfizer’s reduced effectiveness in protecting against the omicron variant, a World Health Organization (WHO) official said existing vaccines should be able to provide adequate protection against severe cases, even with the new variant.
According to WHO’s Dr Mike Ryan, there was no sign yet that omicron would be better able to evade vaccines than other variants.
“We have very effective vaccines that have been shown to be effective against all variants so far, in terms of serious illness and hospitalization, and there is no reason to expect it not. or not ”for omicron, Dr Ryan, WHO’s emergency director, told AFP news agency.
He added that the initial data suggested that the omicron did not cause more serious illness but became milder.
“If anything, the direction is towards less severity,” he said.

Pfizer offers less protection against omicron than other variants

Researchers in South Africa found in an early study that Pfizer’s vaccine offered some protection against the new omicron variant, but less than that provided with other variants.
Researchers at the Africa Health Research Institute in Durban conducted the first experiment to assess the effectiveness of the Pfizer vaccine on omicron and found that it resulted in an approximately 40-fold reduction in the levels of neutralizing antibodies produced by people who had received two doses of Pfizer. -BioNTech SE shot, compared to the variant detected in China almost two years ago.
Alex Sigal, head of research at the lab, said the loss of immune protection is “robust, but not complete” and that further efficacy studies are needed to determine the extent of protection Pfizer can provide, adding that a booster dose may increase. protection.
“A good booster would likely lower your risk of infection, especially severe infection leading to more serious illness,” the researcher said, as quoted by the Bloomberg News Agency. “People who haven’t had a booster should get one, and people who have already been infected should be vaccinated. “
