BBV154 is an intranasal replication-deficient chimpanzee adenovirus SARS-CoV-2 vectored vaccine. In other words,2 less to 1 less people per 1000 did not develop the outcome because of the vaccine. Even though India has another producer of vaccines, Hyderabad-based Bharat Biotech, it is pretty much a Serum Institute of India show in this country. Bharat Biotech says its vaccine, COVAXIN, shows an interim vaccine efficacy of 81 percent in late-stage clinical trials. It has not been tested in the U.S., which has not authorized it for any age groups. The following non-comparative studies have reported efficacy or safety data: Srivastava et al. Krishna Ella: How a farmer's son gave India its first successful New Delhi: Earlier this month, a letter from Dr Balram Bhargava, the director general of the Indian Council of Medical Research (ICMR), proposing 15 August as the release deadline for Covaxin, a potential Covid-19 vaccine, set the cat among the pigeons. A protective response was observed with increasing SARS-CoV-2 specific IgG and neutralizing antibody titers from 3rd week post-immunization. All formulations generated significantly high antigen-binding and neutralizing antibody titers, at both concentrations, in all three species. This is the same as saying that the intervention led to an absolute risk reduction of 66%, or that the intervention reduced the risk of contracting COVID-19 (>60y) by 66 percentage points. Drug Name COVAXIN (BBV152) Developers Bharat Biotech, the Indian Council of Medical Research (ICMR) and National Institute of Virology (NIV) Current Indication Covid-19 Market Sector Infectious diseases "Manufacturing scale-up has been carried out in .

Vial volume: 2.5 mL. The 'cytokine storm' induced by excess T cells has been shown to accentuate the pathogenesis of COVID-19 [Qiang Gao, 2020 ]. When the BBV154 vaccine is administered into a person, the immune cells in the body will express the stabilised spike protein. SAGE/WHO: Sinopharm/BIBP COVID-19 vaccine combined with any other EUL COVID-19 vaccine is considered a complete primary series. ISP/Chile: Two doses (0.5 mL) 2-4 weeks apart and a booster (third) dose provided 2 months after. It was first registered in November 2020 and enrolled 25800 adults of 18 years of age or older, that received two intramuscular 6 g Algel-IMDG doses of BBV152 or placebo on days 0 and 28. The reactivity profile of CD4+ T cells acquired from natural infection was comparable with that of the vaccine, except that the median decline was ~2-fold for Beta (P=0.0003) [Vikkurthi R, 2022 ]. The study results showed that VE in fully vaccinated individuals was 71% (95% CI 57 to 81%) against severe COVID-19 and that it was significantly higher (P = 0.027) than partial vaccination [39% (95% CI: 2-62%)]. All formulations generated significantly high antigen-binding and neutralizing antibody titers, at both concentrations, in all three species. The Sputnik V vaccine, developed by Moscow's Gamaleya Institute, had generated some controversy initially after being rolled out before the final trial data had been released. According to Bharat Biotech, the advantages of BBV154 are that it is non-invasive and needle-free, can be administered easily, is ideally suited for children and adults, and has scalable manufacturing.

Ocugen now holds the commercialisation rights for COVAXIN for all of North America. The relative risk of local adverse events after the 1st dose in the group that received Bharat Biotech COVID-19 vaccine, versus the group that received control vaccine was 1.08 (95% CI 0.94 to 1.23). [1] As of October 2021, 110.6 million people in India have received Covaxin. Excipients250 g of aluminum hydroxide gel.15 g of TLR 7/8 (imidazoquinolinone)2.5 mg of 2-phenoxyethanol.0.5 mL of phosphate buffer saline. Vadrevu et al. WHO recommends using the Sinovac COVID-19 vaccine in pregnant women only if the benefits of vaccination outweigh the potential risks. Immunocompromised personsRandomized trialsThere are no phase 3 randomized trials that have yet reported outcome data.In the phase 1/2 trial BBIL/BBV152-A/2020, immunocompromised patients were excluded, so no data are available for this subgroup [Ella R, 2021 ]. DNA: Eye removed in the name of free operation. TransmissionNo studies reported or assessed this outcome. This is based on the following considerations: (a) Vaccine effectiveness is expected to be similar in breastfeeding women as in other adults, and (b) Bharat Biotech COVID-19 is not a live virus vaccine, and it is biologically and clinically unlikely to pose a risk to the breastfeeding child.WHO does not recommend discontinuing breastfeeding after vaccination.Persons living with HIV [WHO, 2022 ].Data on the administration of the Bharat Biotech COVID-19 vaccine are currently insufficient to allow the assessment of efficacy for persons living with HIV.Given that the vaccine is nonreplicating, persons living with HIV who are well controlled may be vaccinated with the standard primary series of two doses. ANMAT/Argentina: Two doses (0.5 mL each) 3 weeks apart. Which means that 500 people need to receive the vaccine for one of them to not contract serious adverse events. What is the name of Bharat Biotech vaccine? WHO recommends the following research and post-authorization monitoring activities: They had just returned from the US, where Ella completed his PhD at the University of Wisconsin-Madison. A health worker administers a dose of the Sinovac Biotech Covid-19 - Serious adverse events, anaphylaxis and other serious allergic reactions, Bells palsy, cases of multisystem inflammatory syndrome following vaccination, cases of COVID-19 following vaccination that result in hospitalization or death. GBS has been reported very rarely following vaccination with Janssen COVID-19 vaccine.
