Barouch has been working on the development of a COVID-19 vaccine since January, when Chinese scientists released the SARS-CoV-2 genome. Fortunately, NIAID's decades-long support and conduct of coronavirus and vaccine research laid . The vaccine uses a common cold virus, called adenovirus serotype 26 (Ad26), to deliver the SARS-CoV-2 spike protein into host cells, where it stimulates the body to raise immune responses against the coronavirus. Primate keeper Erin Stromberg administers a COVID vaccine to 24-year-old Bornean orangutan Kyle. Cell culture studies show increased lung cell entry of the SARS-CoV-2 variants Delta and Delta Plus and reduced inhibition by antibodies. NEW YORK & MAINZ, Germany--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced preliminary preclinical data in mouse and non-human primate models from their BNT162b2 mRNA-based vaccine program against SARS-CoV-2, the virus that causes COVID-19 disease. Investigators at the School of Medicine and several other institutions have shown that a new type of vaccination can substantially enhance and sustain protection from HIV.. A paper describing the vaccine, which was given to monkeys, was published online May 11 in Nature Medicine.The findings carry broad implications for immunologists pursuing vaccines for the coronavirus and better vaccines . The results shed much-needed light on the . The vaccines also primed the immune system of the pigs to mount a much more vigorous immune response to the infection. Whether potential COVID-19 vaccines will induce protective immunity against the SARS-CoV-2 virus remains a key unanswered question. Antibody and T-cell responses were assessed before . The RBD dimer reported in this study, which shows robust immunogenicity and efficacy both in mice and non-human primates, is a potent COVID-19 vaccine candidate and worth further development. Luckily, a team of scientists at the Beth Israel Deaconess Medical Center have some good news in that department. In a non-human primate preclinical study, immunization . BOSTON — Citizens around the globe are placing their collective hopes on the speedy development of an effective coronavirus vaccine. The animals got their first dose in mid-October, and will receive their second in early November The zoo received 66 doses of the vaccine, specifically designed for . The RBD dimer reported in this study, which shows robust immunogenicity and efficacy both in mice and non-human primates, is a potent COVID-19 vaccine candidate and worth further development. Such results might be explained by reports that the virus can linger in our systems. The California National Primate Research Center (CNPRC) plays a pivotal role in these efforts—from partnering with UC Davis Health and the UC Davis Center for Immunology and Infectious Disease (CIID) to develop a successful diagnostic test that has significantly boosted California's testing capacity, to working with the CIID . A t the start of 2021, four orangutans and five bonobos became the first great apes at a US zoo to receive Covid-19 vaccinations. June 26, 2020 - Vaxart, Inc. announced that its oral COVID-19 vaccine has been selected to participate in a non-human primate challenge study, organized and funded by Operation Warp Speed, a new national program to provide substantial quantities of safe, effective vaccines for Americans by January 2021. This release contains forward-looking information about Pfizer's efforts to combat COVID-19, the collaboration between BioNTech and Pfizer to develop a potential COVID-19 vaccine, the BNT162 . Early research to assess vaccine efficacy using COVID‑19-specific animal models, such as ACE2-transgenic mice, other laboratory animals, and non-human primates, indicates a need for biosafety-level 3 containment measures for handling live viruses, and international coordination to ensure standardized safety procedures. This is the first time an experimental COVID-19 vaccine tested in nonhuman primates has been shown to produce such rapid viral control in the upper airway, the investigators note. The caveat is that the data is from preclinical, non-human primate studies. Two groups addressed this concern in nonhuman primates in two partially manufacturer-supported studies. Trials involving nonhuman primates at UL Lafayette's New Iberia Research Center helped determine the effectiveness of the Pfizer-BioNTech vaccine, the world's first fully tested COVID-19 immunization approved for emergency use.
