A phase I/II clinical trial has been conducted in China since April 2020. NMPA conducted on-site inspections of the phase I/II clinical trials between November 24 and 30, 2020, and authenticity complied. CoronaVac, an inactivated whole-virion SARS-CoV-2 vaccine, has been shown to be well tolerated with a good safety profile in individuals aged 18 years and older in phase 1/2 trials, and provided a good humoral response against SARS-CoV-2. We present the interim efficacy and safety results of a phase 3 clinical trial of CoronaVac in Turkey. Trials, 21(1), 1-3. This clinical trial is designed to assess the safety, reactogenicity and immunogenicity of mRNA-1273 manufactured by ModernaTX, Inc. mRNA-1273 is a novel lipid nanoparticle (LNP)-encapsulated mRNA-based vaccine that encodes for a full-length, prefusion stabilized spike (S) Results Neutralizing antibody titres dropped below the seropositive cutoff of 8 at 6 months after the primary vaccination in all vaccine groups in the phase 1/2 trial. Phase 1 results came in late May, as did the start of a mid-stage trial. Sinopharm and Sinovacs vaccines account for the bulk of shots given in China, which has so far inoculated 243 million people. Sinovacs efficacy. Sinovac started an efficacy trial with 14,000 child participants across multiple countries in September. Second interim analysis of phase 3 results in late April 2021 found 78% efficacy against mild-to-moderate infection and 100% efficacy against severe COVID-19. Interim phase 3 results reported March 2021 in India reported 81% efficacy. A third dose given 8 months or more after the second dose significantly increased neutralizing antibody levels. report preclinical results of an early vaccine candidate called PiCoVacc, which protected rhesus macaque monkeys against SARS-CoV-2 infection when analyzed in short-term studies. The researchers obtained multiple SARS-CoV-2 strains from 11 Global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to an urgent race to develop a vaccine. Phase III results from Brazil previously showed 50.7% efficacy at preventing symptomatic infections and 83.7% effective in preventing mild cases needing treatment. Between April 16 and April 25, 2020, 144 participants were enrolled in the phase 1 trial, and between May 3 and May 5, 2020, 600 participants were enrolled in the phase 2 trial. Received EUA in India in January 2021 after a fully enrolled phase 3 trial (n ~25,800). Zhu Fengcai, one of the paper's authors, said those results - based on 144 participants in the phase one trial and 600 in the phase two trial - meant the vaccine was "suitable for emergency use". The study will be double-blind placebo-controlled trial with participants randomly allocated 1:1 to placebo and vaccine arms. However, our estimates are lower than the vaccine effectiveness recently reported in Turkey (83.5%; 95% CI, 65.4 to 92.1), 27,28 possibly owing to The preliminary results indicate a favorable safety and immunogenicity profile with a two-dose vaccine schedule. In the 3 g group (the licensed formulation), GMT increased to 305 [95%CI 215.3-432.0] on day 7 following the Die Nebenwirkungen lagen unter 20 %, die hufigsten waren Mdigkeit und Schmerzen an der Einstichstelle. Double-Blind, Randomized, Placebo-Controlled Phase III Clinical Trial to Evaluate the Efficacy and Safety of treating Healthcare Professionals with the Adsorbed COVID-19 (Inactivated) Vaccine Manufactured by SinovacPROFISCOV: A structured summary of a study protocol for a randomised controlled trial. In July, Sinovac began Phase III trials in Chile with 14,000 participants for children and adolescents and expand from 6 months to 17 years old. but they have yet to publish full trial results. Malaysian children aged 3 to 11 to join Sinovac vaccine trial. A Phase 3 study began on July 27 and, four months later, delivered strongly positive results that indicated the vaccine was 94% effective in preventing COVID-19. The finding was a dramatic achievement. Eine Phase-3-Studie an rund 10.000 Probanden in der Trkei zeigte in einem rund 43-tgigen Beobachtungszeitraum eine Schutzwirkung von 83,5 % gegen die symptomatische Erkrankung, keiner der Geimpften wurde hospitalisiert. In Phase II, the clinical study is expanded and vaccine is given to people who have characteristics (such as age and physical health) similar to those for whom the new vaccine is intended. Its approval in China was based on smaller phase 1 and phase 2 trials. Phase 3 trials have been testing CoronaVac since mid-2020 in Brazil, Indonesia, Chile, and Turkey, the authors noted. A large phase 3 trial in Brazil showed that two doses, administered at an interval of 14 days, had an efficacy of 51% against symptomatic SARS-CoV-2 infection, 100% against severe COVID-19, and 100% against hospitalization starting 14 days after receiving the second dose, as reported by WHO. Vaccine clinical trial applications submitted to the Food and Drug Administration (Screengrab) Three clinical trial phases are required for a vaccine candidate to be evaluated on its safety, efficacy, and quality. Phase III results from Turkey published in The Lancet showed an efficacy of 84% based on 10,218 participants in the trials. The authors conducted a randomised, double-blind, controlled phase 1/2 clinical trial of CoronaVac in healthy children and adolescents aged 3-17 years in Zanhuang County, China. This is a phase III clinical trial to assess efficacy and safety of the Adsorbed COVID-19 (inactivated) vaccine manufactured by Sinovac in health care professionals. Methods: We did a randomised, double-blind, placebo-controlled, phase 1/2 clinical trial of CoronaVac in healthy adults aged 60 years and older in Renqiu (Hebei, China). Gao et al. No significant changes in inflammatory factors were observed indicating a small risk of immunopathology induced by the SARS-CoV-2 vaccine . 5% relative to placebo) and COVID-19-related hospitalisation (100%) at least 14 days after the second dose. A large phase 3 trial in Brazil showed that two doses, administered at an interval of 14 days, had an efficacy of 51% against symptomatic SARS-CoV-2 infection, 100% against severe COVID-19, and 100% against hospitalization starting 14 days after receiving the second dose. Phase II clinical trial Vaccine is given to a larger group of people who have characteristics (such as age and physical health) similar to those for whom the new vaccine is intended Phase III clinical trial Vaccine is given to thousands of people and tested for efficacy and safety Results of Phase III trials. 743 participants received at least one dose of investigational product (n=143 for & Gast, C. (2020). Between October 31 and December 2, 2020, 72 participants were enrolled in phase 1, with 480 participants enrolled in phase 2 between December 12 and December 30, 2020. By. As for Sinovac and Clover, the FDA is still waiting for them to submit additional documents needed for the review of their application. with the 0,14 procedure was selected to enter the phase III clinical trial to explore the basic data of the body protection effect in a short time. In Phase III, the vaccine is given to thousands of people and tested for efficacy and safety. Phase 3: NCT04470427: PiCoVacc | (Anon, 2020B) Sinovac: The phase 1/2 clinical trials of the inactivated viral vaccine candidate PiCoVacc demonstrated that the vaccine induces neutralizing antibodies with a seroconversion rate of 90% in a 0,14 day schedule. Vaccine or placebo was given by intramuscular injection in two doses (days 0 and 28). During Phase I, small groups of people receive the trial vaccine. Peer-reviewed Phase III results from Turkey showed an efficacy of 83.5% (95% CI, 65.4 92.1%).
