He said that two doses of Moderna’s Covid-19 vaccine had a “substantially weak" neutralising activity towards Omicron, referencing data from the National Institute of Allergy and Infectious Diseases, which he directs.


There Is No Need For Omicron Specific Booster Shot Says Fauci

Booster doses of currently existing Covid-19 vaccinations are effective against the coronavirus variant Omicron, and there does not seem to be a need for variant-specific boosters, according to top US infectious disease specialist Anthony Fauci.

Our booster vaccine regimens work against Omicron. At this point, there is no need for a variant-specific booster,” Fauci told reporters.

He said that two doses of Moderna’s Covid-19 vaccine had a “substantially weak" neutralising activity towards Omicron, referencing data from the National Institute of Allergy and Infectious Diseases, which he directs.

However, if you look at two weeks post the third dose, note the substantial degree of elevation of the neutralising title; well within the range of neutralising Omicron,” he said of the study’s results, which were co-authored by Moderna and the NIAID.

BioNTech and Pfizer said last week that a three-shot course of their vaccine was effective in neutralising Omicron in a laboratory test, but that two doses resulted in significantly lesser neutralising antibodies.

J&J has yet to share any data on the effectiveness of their vaccination against the new coronavirus variant.

According to a research published Tuesday, the three Covid-19 vaccines approved in the United States seem to be much less effective against Omicron in laboratory testing, although a booster dose likely recovers the majority of protection.

At least 36 states have reported cases of the variant, which accounts for around 3% of Covid-19 cases in the country, according to US Centres for Disease Control and Prevention Director Rochelle Walensky during the same briefing. She emphasised that the Delta variation continues to account for the great majority of cases.

We expect to see the proportion of Omicron cases here in the United States continue to grow in the coming weeks. Early data suggests that Omicron is more transmissible than Delta, with a doubling time of about two days,” Walensky said.

She said that although authorities are beginning to detect a surge in Covid-19 infections among fully vaccinated nursing home residents, individuals who have had a booster vaccination have a tenfold lower infection rate.
