The company plans to share the data with government health officials.<blockquote>Moderna在一份新闻稿中披露了其助推器结果，该结果尚未经过同行评审并发表在科学期刊上。该公司计划与政府卫生官员分享这些数据。</blockquote> The Omicron variant was identified in late November in southern Africa and has now spread to many countries, including the U.S.<blockquote>奥密克戎变种于11月下旬在南部非洲被发现，现已传播到包括美国在内的许多国家。</blockquote> Early studies suggest it spreads faster and reinfects people more easily than other variants and it evades vaccine-induced antibodies to a greater degree. It isn’t known yet whether Omicron causes more or less severe Covid-19.<blockquote>早期研究表明，它比其他变种传播更快，更容易再次感染人，而且它在更大程度上逃避疫苗诱导的抗体。目前尚不清楚奥密克戎会导致更严重还是更严重的Covid-19。</blockquote> The new data may reinforce calls by public-health officials for vaccinated people to get booster shots. In the U.S., only about 29.5% of fully vaccinated people have received booster doses, according to the Centers for Disease Control and Prevention.<blockquote>新数据可能会加强公共卫生官员对接种疫苗的人进行加强注射的评级。根据疾病控制和预防中心的数据，在美国，只有约29.5%的完全接种疫苗的人接受了加强剂量。</blockquote> Moderna also found that using a full dose for the third shot packed a more powerful punch than the authorized booster dose. A third full dose increased neutralizing antibodies against Omicron about 83 times more than pre-boost levels.<blockquote>Moderna还发现，使用全剂量进行第三次注射比授权的加强剂量具有更强大的冲击力。第三次全剂量使针对奥密克戎病的中和抗体比加强前水平增加了约83倍。</blockquote> Dr. Burton said government regulators may want to consider recommending the higher-dose boosters to increase protection, at least among people at higher risk of more severe Covid-19.<blockquote>伯顿博士说，政府监管机构可能会考虑推荐更高剂量的加强剂来增加保护，至少在更严重的Covid-19风险较高的人群中是这样。</blockquote> However, in a separate study, Moderna said people receiving the higher-dose booster had more frequent adverse reactions than those who received the lower dose.<blockquote>然而，在另一项研究中，Moderna表示，接受较高剂量加强剂的人比接受较低剂量的人出现更频繁的不良反应。</blockquote> Dr. Burton said the reactions include headache, fever and joint stiffness and should be balanced against the potential benefits of a higher-dose booster.<blockquote>伯顿博士说，这些反应包括头痛、发烧和关节僵硬，应该与更高剂量加强剂的潜在益处相平衡。</blockquote> Moderna also tested other experimental booster shots that target older variants, including Delta, and found they provided a comparable boost to antibody levels against Omicron as its original vaccine booster shot.<blockquote>Moderna还测试了其他针对较老变种（包括Delta）的实验性加强注射，发现它们提供的针对奥密克戎病毒的抗体水平与其原始疫苗加强注射相当。</blockquote> Pfizer and BioNTech said a third dose of their Covid-19 vaccine increased neutralizing antibodies against Omicron compared with just two doses.<blockquote>辉瑞和BioNTech表示，与仅接种两剂相比，第三剂Covid-19疫苗增加了针对奥密克戎病的中和抗体。</blockquote> Given the speed of Omicron’s spread, Moderna said its near-term priority will be to continue making booster shots of its original vaccine available.<blockquote>鉴于奥密克戎病毒传播的速度，Moderna表示，其近期的首要任务将是继续提供其原始疫苗的加强注射。</blockquote> It said it would keep working on an Omicron-specific booster shot, in case it is needed. Moderna expects to start clinical trials of an Omicron-specific booster in early 2022.<blockquote>该公司表示，如果需要，将继续研究针对奥密克戎的加强注射。Moderna预计将于2022年初开始奥密克戎病专用加强剂的临床试验。</blockquote> The new data on Moderna’s booster and Omicron came from lab tests that mix blood samples from vaccinated people with an engineered virus that resembles the Omicron variant. The tests were conducted at Duke University Medical Center labs that were established by the National Institute of Allergy and Infectious Diseases, Moderna said.<blockquote>关于Moderna加强剂和奥密克戎的新数据来自实验室测试，这些测试将接种疫苗者的血液样本与类似奥密克戎变种的工程病毒混合。Moderna表示，这些测试是在杜克大学医学中心实验室进行的，该实验室由国家过敏和传染病研究所建立。</blockquote>","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html;
