Updated top-line results released for up to six months after the second dose confirmed efficacy at 91.3%.<blockquote>疫苗效力：辉瑞-BioNTech去年12月发布的3期试验中期数据显示，该疫苗耐受性良好，在第二剂疫苗接种后7天或更长时间内，在预防新冠肺炎方面表现出95%的疗效。第二次给药后长达六个月发布的更新顶线结果证实疗效为91.3%。</blockquote> The vaccine was found 100% effective against severe disease as defined by the U.S. Centers for Disease Control and Prevention, and 95.3% effective against severe COVID-19 as defined by the FDA. It was also proved effective against the U.K. strain in lab studies.<blockquote>该疫苗被发现对美国疾病控制和预防中心定义的严重疾病100%有效，对FDA定义的严重新冠肺炎95.3%有效。在实验室研究中，它也被证明对英国菌株有效。</blockquote> Moderna's vaccine showed efficacy of 94.1% against COVID-19. The company announced in May initial data from its Phase 2 study showing that a single 50 mcg dose of mRNA-1273 or mRNA-1273.351 given as a booster to previously vaccinated individuals increased neutralizing antibody titer responses against SARS-CoV-2 and two variants of concern, B.1.351, first identified in South Africa, and P.1, first identified in Brazil.<blockquote>Moderna的疫苗对新冠肺炎的有效性为94.1%。该公司于5月宣布了其2期研究的初步数据，显示向先前接种疫苗的个体给予50微克剂量的mRNA-1273或mRNA-1273.351作为加强剂，增加了针对新型冠状病毒病毒和两种令人担忧的变异体的中和抗体滴度反应，B.1.351，首次在南非发现，P.1，首次在巴西发现。</blockquote> Novavax's investigational vaccine demonstrated 100% protection against moderate and severe disease not involving variants of concern or variants of interest.<blockquote>Novavax的研究疫苗对中度和重度疾病表现出100%的保护作用，不涉及令人担忧的变异体或感兴趣的变异体。</blockquote> Against variants of concern and variants of interest, the efficacy was 93.2% and in high-risk populations, defined as over 65 or under 65 years with certain comorbidities or having circumstances with frequent COVID-19 exposure, the efficacy was 91%.<blockquote>针对关注变异体和感兴趣变异体，疗效为93.2%，在高危人群（定义为65岁以上或65岁以下，患有某些合并症或经常暴露于新冠肺炎的情况）中，疗效为91%。</blockquote> Overall efficacy was 90.4%, meeting the primary endpoint.<blockquote>总疗效为90.4%，达到主要终点。</blockquote> Cantor Fitzgerald On Novavax's Vaccine:A differentiating factor for NVX-2373&nbsp;is that it showed vaccine efficacy of 93.2% against VoC/VoI, which demonstrates protection across a broad range of SARS-CoV-2 strains, Cantor Fitzgerald analyst Charles Duncan said in a Monday morning note.<blockquote>坎托·菲茨杰拉德谈Novavax的疫苗：Cantor Fitzgerald分析师Charles Duncan在周一早间报告中表示，NVX-2373的一个与众不同之处在于，它对VoC/VoI表现出93.2%的疫苗效力，这证明了对多种新型冠状病毒毒株的保护作用。</blockquote> \"Overall, these results enhance our conviction for a differentiated clinical and logistics profile from the SARS-CoV-2 vaccine candidate ‘2373,\" the analyst said.<blockquote>该分析师表示：“总体而言，这些结果增强了我们对新型冠状病毒候选疫苗‘2373具有差异化临床和物流特征的信念。”</blockquote> Showing efficacy against new strains in two Phase 3 clinical trials, rather than extrapolating potential efficacy from a neutralizing antibody assay conducted in a petri dish, differentiates NVX-CoV2373 from other vaccines that have emergency use authorization, he said.<blockquote>他说，在两项3期临床试验中显示出对新毒株的功效，而不是从培养皿中进行的中和抗体测定中推断出潜在功效，这将NVX-CoV2373与其他获得紧急使用授权的疫苗区分开来。</blockquote> This profile, according to Cantor reduces regulatory/ commercial risk for the ‘2373 SARS-CoV-2 prophylactic vaccine candidate and, with positive Phase 3 data for NanoFlu reported in March 2020, should raise the profile for Novavax's platform as a whole.<blockquote>Cantor表示，这一概况降低了'2373新型冠状病毒预防性候选疫苗的监管/商业风险，并且随着2020年3月报告的NanoFlu 3期积极数据，应该会提高Novavax平台的整体形象。</blockquote> Vaccine Safety Data:Pfizer-BioNTech's vaccine showed a favorable tolerability and safety profile, with the most common adverse events from&nbsp;BNT162b2 being transient, mild to moderate pain at the injection site, fatigue and headache, and these generally resolved within two days.<blockquote>疫苗安全性数据：辉瑞-BioNTech的疫苗显示出良好的耐受性和安全性，BNT 162 B 2最常见的不良事件是注射部位的短暂、轻度至中度疼痛、疲劳和头痛，这些通常在两天内消退。</blockquote> For Moderna, the most common adverse reactions included injection site pain, fatigue, myalgia, arthralgia, headache, and erythema/redness at the injection site. Solicited adverse reactions increased in frequency and severity in the mRNA-1273 group after the second dose.<blockquote>对于Moderna，最常见的不良反应包括注射部位疼痛、疲劳、肌痛、关节痛、头痛和注射部位红斑/发红。在第二次给药后，mRNA-1273组中引起的不良反应的频率和严重程度增加。</blockquote> Preliminary safety data from Novavax's trial showed the vaccine to be generally well-tolerated. Serious and severe adverse events were low in number and balanced between vaccine and placebo groups.<blockquote>Novavax试验的初步安全性数据显示，该疫苗总体耐受性良好。严重和严重不良事件的数量较少，并且在疫苗组和安慰剂组之间平衡。</blockquote> In assessing reactogenicity seven&nbsp;days after dose one&nbsp;and dose two, injection site pain and tenderness, generally mild to moderate in severity, were the most common local symptoms, lasting less than three days. Fatigue, headache and muscle pain were the most common systemic symptoms, lasting less than two days.<blockquote>在第1剂和第2剂后7天评估反应原性时，注射部位疼痛和压痛（通常严重程度为轻度至中度）是最常见的局部症状，持续时间少于3天。疲劳、头痛和肌肉疼痛是最常见的全身症状，持续时间不到两天。</blockquote>","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>Novavax Vs.

The injected vaccine then stimulates the immune system to produce antibodies and T-cell immune responses.\nThe Vaccine Doses: The vaccines from each of the three companies require two doses. Each dose consists of 30 mcg for Pfizer and 100 mcg for Moderna, while for Novavax, each vaccine dose consists of 5 mcg of NVX-CoV2371 and 50 mcg of Matrix-M1 adjuvant that are co-formulated.\nThe interval between the two doses — the priming and booster dose — is 21 days each for Pfizer and Novavax and 28 days for Moderna.\nThe Target Population: The original late-stage trial of Pfizer-BioNTech evaluated the vaccine in participants ages 16 years and older. The trial enrolled 43,448 participants.\nModerna'sPhase 3 COVE study enrolled 30,000 participants ages 18 years and up.\nSince then, these two companies have obtained authorizations for their respective vaccines to be used in adolescents.\nBothcompanieshave also initiated studies in the pediatric population.\nNovavax's study enrolled 29,960 participants 18 years of age and older across 119 sites in the U.S. and Mexico. The placebo-controlled portion of PREVENT-19 continues in adolescents from 12 to less than 18 years of age and recently completed enrollment with 2,248 participants.\nVaccine Logistics: Pfizer recently secured FDA authorization for storing undiluted, thawed vaccine vials in the refrigerator at 2°C to 8°C for up to one month.\nPreviously, thawed, undiluted vaccine vials could be stored in the refrigerator for up to five days. Moderna's vaccine can be stored refrigerated between 2° and 8°C for up to 30 days prior to first use.\nNVX-CoV2373 is stored and stable at 2°- 8°C, allowing the use of existing vaccine supply chain channels for its distribution. It is packaged in a ready-to-use liquid formulation in 10-dose vials.\nVaccine Efficacy: Interim data from Pfizer-BioNTech's Phase 3 trials released in December showed the vaccine was well-tolerated and demonstrated 95% efficacy in preventing COVID-19 in those without prior infection seven days or more after the second dose. Updated top-line results released for up to six months after the second dose confirmed efficacy at 91.3%.\nThe vaccine was found 100% effective against severe disease as defined by the U.S. Centers for Disease Control and Prevention, and 95.3% effective against severe COVID-19 as defined by the FDA. It was also proved effective against the U.K. strain in lab studies.\nModerna's vaccine showed efficacy of 94.1% against COVID-19. The company announced in May initial data from its Phase 2 study showing that a single 50 mcg dose of mRNA-1273 or mRNA-1273.351 given as a booster to previously vaccinated individuals increased neutralizing antibody titer responses against SARS-CoV-2 and two variants of concern, B.1.351, first identified in South Africa, and P.1, first identified in Brazil.\nNovavax's investigational vaccine demonstrated 100% protection against moderate and severe disease not involving variants of concern or variants of interest.\nAgainst variants of concern and variants of interest, the efficacy was 93.2% and in high-risk populations, defined as over 65 or under 65 years with certain comorbidities or having circumstances with frequent COVID-19 exposure, the efficacy was 91%.\nOverall efficacy was 90.4%, meeting the primary endpoint.\nCantor Fitzgerald On Novavax's Vaccine:A differentiating factor for NVX-2373 is that it showed vaccine efficacy of 93.2% against VoC/VoI, which demonstrates protection across a broad range of SARS-CoV-2 strains, Cantor Fitzgerald analyst Charles Duncan said in a Monday morning note.\n\"Overall, these results enhance our conviction for a differentiated clinical and logistics profile from the SARS-CoV-2 vaccine candidate ‘2373,\" the analyst said.\nShowing efficacy against new strains in two Phase 3 clinical trials, rather than extrapolating potential efficacy from a neutralizing antibody assay conducted in a petri dish, differentiates NVX-CoV2373 from other vaccines that have emergency use authorization, he said.\nThis profile, according to Cantor reduces regulatory/ commercial risk for the ‘2373 SARS-CoV-2 prophylactic vaccine candidate and, with positive Phase 3 data for NanoFlu reported in March 2020, should raise the profile for Novavax's platform as a whole.\nVaccine Safety Data:Pfizer-BioNTech's vaccine showed a favorable tolerability and safety profile, with the most common adverse events from BNT162b2 being transient, mild to moderate pain at the injection site, fatigue and headache, and these generally resolved within two days.\nFor Moderna, the most common adverse reactions included injection site pain, fatigue, myalgia, arthralgia, headache, and erythema/redness at the injection site.
