All talk to spook people and cause uneasiness. One minute good the next minute no good must have cocktails of vaccination… people are dead tired and need a break.

The preliminary data in the manuscript has not yet been peer reviewed.\nBlood from five out of six people who had been vaccinated as well as previously infected with COVID-19 still neutralized the Omicron variant, the manuscript said.\n\"These results are better than I expected. The more antibodies you got, the more chance you'll be protected from Omicron,\" Sigal said on Twitter.\nHe said the lab had not tested the variant against blood from people who had received a booster dose, because they are not available in South Africa yet.\nAccording to the manuscript, the lab observed a 41-fold decline in levels of neutralizing antibodies against the Omicron variant.\nSigal said on Twitter that figure is likely to be adjusted after his lab does more experiments.\nWhile neutralizing antibodies are an indicator of the body's immune response, scientists believe other kinds of cells such as B-cells and T-cells also are stimulated by the vaccines and help protect against the effects of the coronavirus.\nThe Omicron variant, first detected in southern Africa last month, has triggered alarms globally of another surge in infections, with more than two dozen countries from Japan to the United States reporting cases.\nThe World Health Organization classified it on Nov. 26 as a \"variant of concern,\" but said there was no evidence to support the need for new vaccines specifically designed to tackle the Omicron variant with its many mutations.\nThere is not significant data yet on how vaccines from Moderna, Johnson & Johnson and other drugmakers hold up against the new variant. All the manufacturers, including Pfizer and BioNTech, are expected to release their own data within weeks.\nBioNTech CEO Ugur Sahin told NBC News on Tuesday that the drugmaker has data coming on Wednesday or Thursday related to the new variant.\nTop U.S. infectious disease expert Dr. Anthony Fauci said on Tuesday that preliminary evidence indicates that the Omicron variant of the coronavirus likely has a higher degree of transmissibility but is less severe.\nHe said the United States was doing its own tests to determine the protectiveness of the current vaccines against the variant and expects results sometime next week.\nUmer Raffat, an analyst for Evercore ISI, cautioned against reading too much into a single study, noting there has been significant variability in measuring declines in antibody levels in previous lab studies.\n\"Let’s wait for additional studies to draw a mosaic,\" he said.","kind":null,"is_publish_news":true,"is_publish_highlight":true,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"symbols":[],"gpt_button":1},"commentList":[{"id":606723728,"gmtCreate":1638930265999,"gmtModify":1638930709393,"author":{"id":"3582072953259355","authorId":"3582072953259355","name":"Weeckee","avatar":"https://static.laohu8.com/default-avatar.jpg","vip":1,"crmLevel":4,"crmLevelSwitch":0,"idStr":"3582072953259355","authorIdStr":"3582072953259355"},"htmlText":"All talk to spook people and cause uneasiness.
