(14) Notably, Janssen vaccine showed good efficacy against severe or critical disease (73%–82%) across all sites. Neutralizing antibody responses to SARS-CoV-2 variants in vaccinated Ontario long-term care home residents and workers. 2021; Nanduri S, Pilishvili T, Derado G, et al. 2021; Shah A, Gribben C, Bishop J, et al. Janssen COVID-19 Vaccine. 2021; Liu X, Shaw RH, Stuart ASV, Greenland M, Aley PK, Andrews NJ, et al. 2021; Noori M, Nejadghaderi SA, Arshi S, Carson-Chahhoud K, Ansarin K, Kolahi AA, et al. N Engl J Med. Data were added from studies published since the last update that further demonstrate people who are fully vaccinated with a currently authorized mRNA vaccine are protected against asymptomatic infection and, if infected, have a lower viral load than unvaccinated people. For example, if the pertinent issue is a breach of contract, a witness whose evidence proves it was raining when both parties signed the contract is relevant but immaterial. Inflammopharmacology. Other variants that are either no longer detected or are circulating at very low levels in the United States include: Alpha (B.1.1.7), first detected in the United Kingdom; Beta (B.1.351), first detected in South Africa; Gamma (P.1), first detected in Japan/Brazil; Iota (B.1.526), first detected in the United States-New York; Eta (B.1.525), first detected in the United Kingdom/Nigeria; Kappa (B.1.617.1) and B.1.617.3, first detected in India. SARS-CoV-2 delta variant neutralisation after heterologous ChAdOx1-S/BNT162b2 vaccination. 20 University Rd., 6th Floor Table 1b. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2≥15 days after second dose (136-138) Compared with younger individuals, persons aged >80 years have been noted to have reduced T-cell responses, lower neutralizing antibody levels, and less potential antibody diversity (somatic hypermutation), potentially giving this group increased risk for susceptibility to SARS-CoV-2 infection in vaccinated people. 2021; Werbel WA, Boyarsky BJ, Ou MT, Massie AB, Tobian AAR, Garonzik-Wang JM, et al. Vaccines and Related Biological Products Advisory Committee Briefing Document – Sponsor. Epub 2020 May 30. Epub 2017 Jan 22. Impact of Delta on viral burden and vaccine effectiveness against new SARS-CoV-2 infections in the UK. Data from the clinical trials among adults ≥18 years old suggest COVID-19 vaccination protects against symptomatic infection and may also protect against asymptomatic infection. From January through June 2021, COVID-NET data from laboratory-confirmed COVID-19-associated hospitalizations in adults ≥18 years of age for whom vaccination status is known showed 3% of hospitalizations occurred in fully vaccinated persons. All COVID-19 vaccines currently approved or authorized in the United States (Pfizer-BioNTech/Comirnaty, Moderna, and Janssen [Johnson & Johnson]) are effective against COVID-19, including against severe disease, hospitalization, and death. B and T cell responses after a third dose of SARS-CoV-2 vaccine in Kidney Transplant Recipients. Vaccine effectiveness against hospitalization and death is high for all current SARS-CoV-2 variants; emerging data suggest lower effectiveness against confirmed infection and symptomatic disease caused by the Beta, Gamma, and Delta variants compared with the ancestral strain and the Alpha variant. BNT162b2-elicited neutralization of B.1.617 and other SARS-CoV-2 variants. Lancet Respir Med. While vaccine effectiveness against emerging and other SARS-CoV-2 variants will continue to be assessed, available evidence suggests that the COVID-19 vaccines approved or authorized in the United States offer substantial protection against hospitalization and death from emerging variants, including the Delta variant. Antibody response to mRNA SARS-CoV-2 vaccine among kidney transplant recipients – Prospective cohort study. Summary of vaccine efficacy estimates for approved or authorized COVID-19 vaccines. In Acts 5:15-16 we read, “People brought the sick into the streets and laid them on beds and mats so that at least Peter’s shadow might fall on some of them as he passed by. Six-month clinical efficacy for the Pfizer-BioNTech vaccine shows an overall efficacy against infection of 91% and 97% efficacy against severe illness. Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits. June 16, 2020. doi: 10.1377/hlthaff.2020.00818. Years of sustained, coordinated, and vigilant effort will be required to contain the present opioid epidemic and ameliorate its harmful effects on society. Single-dose mRNA vaccine effectiveness against SARS-CoV-2 in healthcare workers extending 16 weeks post-vaccination: a test-negative design from Quebec, Canada.
