Vaccine companies are testing their shots against the variant of concern—and some early data is beginning to emerge.

In a joint press release, the companies said that the study involved looking at blood samples from people who had received either two or three Pfizer vaccine shots, but did not disclose the sample size or how many people the samples were taken from.Newsweek

has contacted Pfizer and BioNTech for comment.According to the companies, the study"[demonstrated] that serum antibodies induced by the Pfizer-BioNTech COVID-19 Vaccine (BNT162b2) neutralize the SARS-CoV-2 Omicron variant after three doses" at a level comparable to"two doses against wild-type and other variants that emerged before Omicron."

The companies added they were still planning to have an Omicron-specific vaccine ready for March if needed.In addition, another studyreleased earlier this week, led by Alex Sigal at the Africa Health Research Institute, looked at what happened when the Omicron variant virus was exposed to the blood of 12 different people who had all received a Pfizer vaccine series. Six of those people had previously had COVID. headtopics.com

The study found there was a 41-fold reduction in neutralization against Omicron compared to an earlier form of SARS-CoV-2, a substantial decrease—though it does not mean the vaccine is 41 times less effective.The study also found the neutralization escape was not complete and that five of the participants, all of whom had been previously infected, showed"relatively high" levels of neutralization against

Omicron.It concluded that previous infection, followed by a vaccination or booster, will"likely confer protection from severe disease in Omicron infection."OnTwitter, Sigal said the study results were"better than I expected of Omicron" and suggested existing methods to deal with COVID would help control the variant.

Just be be clear on something as I'm still awake, this was better than I expected of Omicron. The fact that it still needs the ACE2 receptor and that escape is incomplete means its a tractable problem with the tools we got— Alex Sigal (@sigallab)December 7, 2021

At the same time, the study is early and small and future ones should include samples from people who had received booster shots, tweeted Muge Cevik, clinical lecturer in infectious diseases and medical virology at the U.K.'s University of St. Andrews. In short, more data is needed to paint a definitive picture of Omicron. headtopics.com
