According to PRAC-EMA, the available evidence does not support a causal link between Comirnaty and very rare cases of autoimmune hepatitis (AIH) [13]. Corbevax is also currently being administered to children in the 12-14 age group. ANMAT/Argentina: Two doses (0.5 mL each) 3 weeks apart. COVAXIN also demonstrated promising safety, efficacy and superior response in paediatric patients compared to adults in a Phase II/III clinical study that enrolled 526 children. The Bharat Biotech COVID-19 vaccine (BBV152) is a whole virion inactivated SARS-CoV-2 antigen adsorbed to alum and formulated with a toll-like receptor (TLR) 7/8 agonist Imidazo quinolin gallamide (IMDG) and the preservative 2-phenoxyethanol [WHO, 2022 ]. Covaxin is developed by Bharat Biotech and it is India's first indigenous vaccine against Covid-19. 3D Printing in Healthcare Market Size, Share, Trends Analysis Report By Region, Component (Hardware, Materials, Digital Marketing Trends in Colorectal Cancer. Very rare cases of thrombosis with thrombocytopenia syndrome (TTS) were reported following the first dose of Janssen COVID-19 vaccine. She stated that BBV154 has the double benefit of enabling faster development of variant -specific vaccines and easy nasal delivery. Neutralizing antibodies against homologous and heterologous SARS-CoV-2 variants increased 19- to 97-fold after a third vaccination[Krishna Mohan Vadrevu, 2022 ]. EMA: Single booster dose (0.5 mL) after three months of the primary series or monovalent booster for persons 12 years [2]. The PRAC-EMA has concluded that heavy menstrual bleeding is a side effect of unknown frequency of Spikevax. India has approved nine Covid vaccines, five of which have been locally made. It is a WHO-prequalified international supplier of vaccines among those companies that have earned India the monicker of the pharmacy of the world.. The study enrolled 334 healthcare workers who had contracted COVID-19 of different intensities and were vaccinated with different types of COVID-19 vaccine (Astrazeneca 12.9%, Sinopharm 16.2%, Sputnik 62.3%,Bharat Covaxin 6.9%) at least one month following recovery from the virus, between April 2021 and September 2021. conducted a report on the immunogenicity of the Covaxin booster dose against the ancestral variant and those of concern, at one year of follow-up of the BBIL/BBV152-A/2020 trial. SAGE/WHO: A booster dose should be given 4-6 months after the primary series* and a second booster after 4-6 months for specific population groups**. This means Bharat Biotech COVID-19 vaccine increased the risk of any adverse event by 0%, compared with control vaccine. The multi-centre, double-blind study enrolled 27,000 participants across India. The neutralizing potential: vaccine-induced antibodies declined significantly against the Delta (2-fold vs ancestral; P<0.0001). Outcome: systemic adverse events after the 2nd dose. A protective response was observed with increasing SARS-CoV-2 specific IgG and neutralizing antibody titers from 3rd week post-immunization. In the statement, Suchitra K Ella, Joint Managing Director, Bharat Biotech, said that vectored vaccines enable faster development of target vaccines in response to emerging variants of concern. A recombinant vaccine contains the modified parts of pathogenic organisms such as bacteria or viruses, which stimulate an immune response in the host cells. It is India's first indigenously developed recombinant protein sub-unit vaccine. The first vaccination dose was given to all participants. In persons with history of this extremely rare condition, there is a potential occurrence of CLS flare-up following vaccination with Moderna COVID-19 vaccine [9]. Breadth of RBD-specific B cells in their reactivity to the SARS-CoV-2 variants: A ~2-fold reduction in vaccine-induced IgG+ B cells was observed against the Delta variant. Assessment and reporting of vaccination failures and virus sequence information. Multidose vial of 10 doses (0.5 mL each). In January 2022, Bharat Biotech reported positive results from a Phase II study of COVAXIN in patients aged between 12 and 64 years who received a booster dosage six months after a second dose. The company had unveiled two vaccines against the outbreak of the mosquito-borne Zika virus. No comment, said the company spokesman as the debate raged on. The interim results of the trial were published in a scientific journal on March, 2021 [Ella R, 2021 ]. There is no evidence to suggest the menstrual disorders experienced have any impact on reproduction and fertility [12]. The study enrolled 12,237 participants: 8,248 vaccine group; 3,989 control group. The pharmaceutical industry's most comprehensive news and information delivered every month.

The phase 3 clinical trials of Bharat Biotech 's COVID-19 nasal vaccine have been completed, according to Dr. Krishna Ella, the company's Chairman and Managing Director. The severity of infection can vary from very mild to severe. Preclinical research showed high immunogenicity and protective efficacy in animal challenge studies undertaken in hamsters and non-human primates. PregnancyRandomized trialsThere are no phase 3 randomized trials that have yet reported outcome data. This background document on the Bharat Biotech BBV152 COVAXIN vaccine against COVID-19 was prepared by the Working Group on COVID-19 Vaccines of the Strategic Advisory Group of Experts (SAGE) on Immunization to inform SAGE deliberations. Data not yet available [, 6 months to 5 years of age: 37.8% (20.9-51.1%) [, 6 months to 4 years of age: 80.0% (22.8-94.8%) [, 6 to 23 months of age: 31.5% (27.7-62.0%). 90% of subjects receiving the third dose of COVAXIN showed neutralizing activity against the Omicron variant when tested 28 days after the third dose of serum. The results showed persistence of cell-mediated and humoral immunity up to 12 months after vaccination, despite the decrease in the magnitude of antibody titers. Based on data from different HCWs employed at the All India Institute of Medical Sciences (AIIMS), New Delhi, India, a public-funded, teaching and multi-speciality tertiary care institute, between April 10 and June 24, 2021, the study results showed a vaccine effectiveness of 44% (95% CI 37 to 51) against symptomatic infection, hospitalization or death and a vaccine effectiveness of 61% (95% CI 37 to 76) against hospitalization or death [Sumit Malhotra, 2022 ]. In other words,15 less to 1 less people per 1000 did not develop the outcome because of the vaccine. older adults, health workers, persons with comorbidities), administered 46 months after completion of the primary series.Once high booster dose coverage has been achieved in the highest priority-use group, countries may also consider a booster for other lower priority-use groups.If more than 6 months have elapsed since completion of the primary series, a booster dose should be given at the earliest opportunity. The Lancet - Infectious Diseases Journal, published phase 2 results of the vaccine developed by Hyderabad-based Bharat Biotech. When the BBV154 vaccine is administered into a person, the immune cells in the body will express the stabilised spike protein. The period between virus exposure and symptom onset is known as the incubation phase. as the release deadline for Covaxin, a potential Covid-19 vaccine, set the cat among the pigeons. Currently, Phase I clinical trials for Zika are underway. SexRandomized trialsThere are no phase 3 randomized trials that have yet reported outcome data. Also, the nasal mucosa has an organised immune system because of which the nasal route serves as one of the best regions for vaccination. Thevaccineis derived from the Vero cell platform and manufactured at Bharat Biotechs Bio-Safety Level-3 (BSL-3) high containment facility, which is located in Genome Valley, Hyderabad, India. INVIMA/Colombia: contraindicated in pregnant women. Figure - Forest plot of risk ratio meta-analysis. ANMAT/Argentina: A booster dose should be given at least 4 months after the primary scheme using an mRNA-based or viral vector vaccine. 6g of whole-virion inactivated SARS-CoV-2 antigen (Strain: NIV-2020-770). Currently, there are no studies that have assessed the vaccine immunogenicity outcomes on heterologous regimen. COVAXIN contains 6g of whole-virion inactivated SARS-CoV-2 antigen (Strain: NIV-2020-770). The differential safety of the vaccine in sex groups was not reported in the phase 1/2 trial BBIL/BBV152-A/2020 [Ella R, 2021 ]. Sputnik Light: multidose vial of 5 doses (0.5 mL each). *against confirmed COVID-19 [, 78% (65-86%) Since 10 January, India has also been administering booster shots to healthcare and frontline workers, and those above 60 with comorbidities. 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 ]. In the trials identified in this review, 1597 people not receiving Bharat Biotech COVID-19 vaccine out of 12874 presented this outcome (124 per 1000) versus 1597 out of 12879 in the group that did receive it (124 per 1000). Sharing a study of the intranasal vaccines under clinical trials, Bharat Biotech's Dr Raches Ella had in July . The relative risk of contracting COVID-19 (>60y) in the group that received Bharat Biotech COVID-19 vaccine, versus the group that received control vaccine was 0.34 (95% CI 0.12 to 0.92). The relative risk of any adverse event in the group that received Bharat Biotech COVID-19 vaccine, versus the group that received control vaccine was 1 (95% CI 0.94 to 1.07). The vaccine BBV154 is currently in phase 1-2 clinical trial. He is not visible anymore on youtube, Way back in late Nineties I heard Mr. Prahlad,, the noted marketing professor when he called upon the Industry leaders in a CII meet to address the consumer market with ONE RUPEE ICE CREAM and other consumer products in pouches for all the consumers; he challenged them that this will revolutionaize the market and growth.. In this case, the NNH is 1000. Venous thromboembolism (VTE) has been observed rarely following vaccination with Janssen COVID-19 vaccine. Bharat Biotech was founded in 1996 by Dr Ella, a research scientist in molecular biology, with his wife Suchitra. Soberana 02 ST and Soberana plus ST: monodose vial without thimerosal. Another way of presenting the same information about the absolute effects is the number needed to treat for an additional beneficial/harmful outcome (NNTB/H), the number of participants who need to receive the intervention for one of them to experience the outcome. No doubt we have rains because of such philanthrapists. WHO recommends using the CanSino COVID-19 vaccine in pregnant women only if the benefits of vaccination outweigh the potential risks. assessed immunogenicity of different vaccination regimes in Syrian hamsters (BBV152A, BBV152B, and BBV152C). Ages 12 to 15: 100% (75.3-100.0%) [, Recommended if the benefits of vaccination outweigh the potential risks [, Available data are insufficient to inform vaccine-associated risks in pregnancy [, Available data are insufficient to assess the vaccine-associated risks in pregnancy [, Vaccine effectiveness against COVID-19 declines as for six months after a primary series in the context of variants of concern (including Delta and Omicron variants)[, Vaccine effectiveness against COVID-19 declines as for six months after a primary series in the context of variants of concern (including Delta and Omicron variants [, Vaccine efficacy among ages 6 months through 5 years was evaluated during the, The vaccine efficacy in adults was assessed while, Soberana 02 and Soberana 02 ST: 6 months The participants received two intramuscular injections within 28 days. TransmissionNo studies reported or assessed this outcome. BBV154 is an intranasal replication-deficient chimpanzee adenovirus SARS-CoV-2 vectored vaccine. Another way of presenting the same information about the absolute effects is the number needed to treat for an additional beneficial/harmful outcome (NNTB/H), the number of participants who need to receive the intervention for one of them to experience the outcome.

Sera collected after 6 months after the third dose were evaluated for neutralization efficacy against Delta by PRNT50, obtaining GMT 159.9 (55.8240.8) and a seroconversion rate of 96.8 ( 81.599.8) in the booster group. 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 ]. India's Bharat Biotech said on Tuesday it was likely to export its COVID-19 vaccine to Brazil and the United Arab Emirates this week, a major success for the shot approved at home for emergency use without efficacy data from a late-stage trial. "It promises to become an important tool in mass vaccinations during pandemics and endemics," she said. Local reactions consisted mainly of mild pain at the site of injection (35% of any group after the first dose and less than 25% after the second dose). was a non-comparative study conducted in India, the study analyzed the immune response against wild variants, Delta and Omicron after a first dose of the Bharat vaccine. The study reported data from 4 weeks post immunization. Also Read: Human trials of Bharat Biotechs Covid vaccine Covaxin begin in Rohtak, Dr Ellas message on the Bharat Biotech website reads: At Bharat Biotech, our formula to Lead Innovation has led to healthcare solutions focused on neglected infectious diseases. Two other vaccines have also been given emergency approval - Corbevax for children aged five-12; and Zydus's two-dose jab for children above 12. Vaccine effectiveness over time and whether protection can be prolonged by booster doses. This can potentially reduce infection and transmission of SARS-CoV-2, the causative organism of Covid-19. Ella R et al. Participants showed an increase in antibody titers on day 28 after receiving the booster dose. SAGE/WHO: Two doses (0.5 mL each) 3 to 4 weeks apart. Non-comparative studiesCherian S et al. *against confirmed COVID-19 [, 58% (40-70%) The relative risk of contracting COVID-19 in the group that received Bharat Biotech COVID-19 vaccine, versus the group that received control vaccine was 0.23 (95% CI 0.15 to 0.35). This is the same as saying that the intervention led to an absolute risk reduction of 93%, or that the intervention reduced the risk of contracting severe COVID-19 by 93 percentage points. COVAXIN is an inactivated, indigenous and intramuscular Covid-19 vaccine. When injected, this is expected to trigger an immune response in the body. Soberana 02 and Soberana Plus: Thiomersal, Sputnik V; Gam-COVID-Vac; Adeno-based (rAd26-S+rAd5-S) / Sputnik light. In other words,1 less to 6 more people per 1000 did not develop the outcome because of the vaccine. Individuals with Covid-19 may experience a variety of mild or severe symptoms, which can develop between two and 14 days after exposure to the virus. The aim was to assess the incidence density of reinfection among a cohort of HCWs and estimate the effectiveness of the inactivated whole virion vaccine BBV152 against reinfection. (See the list of ingredients under 'General characteristics' in the extended version).The second dose of the vaccine should NOT BE GIVEN to those who have experienced anaphylaxis to the first dose of Bharat Biotech COVID-19 vaccine. Of the three candidates, BBV152A showed the better response. Ganneru et al assessed preclinical safety of either adjuvant-alone (Algel-IMDG) or three formulations of the vaccine in mice, rats and rabbits. The market value of a company, in total dollars, also called "market capitalization." Market cap is calculated by taking a company's price per . Bharat Biotech, which makes the vaccine, has since published data suggesting 78% efficacy. Allergic reactions [WHO, 2022 ].Persons with a history of anaphylaxis to any other vaccine or injectable therapy should be observed for 30 minutes after vaccination in health care settings where anaphylaxis can be immediately treated.Pregnancy [WHO, 2022 ].Available data from clinical trials are still insufficient to assess vaccine safety or efficacy of the Bharat Biotech COVID-19 vaccine in pregnancy. Since BBV154 is an intranasal vaccine, it has the potential to produce local antibodies in the upper respiratory tract, according to the statement. Bharat Biotechs intranasal Covid-19 vaccine was approved for restricted emergency use in adults, on Tuesday, September 6, 2022. Interchangeability studies within and across COVID-19 vaccine platforms. Read about our approach to external linking. COVID-19 vaccine tracker and landscape Serum Intitute and Bharat Biotech vaccines have to be administered in two doses. However, this increase was insignificant or modest against the delta and omicron variants in people who had been infected before receiving the vaccine [Das, S., 2022 ]. Efficacy outcomesDelta (B.1.617.2)Ella R et al. The country has recorded a small rise in new Covid cases over the past week, with the capital Delhi accounting for almost half of the 2,500 new infections on Tuesday. The government had also approved Johnson & Johnson's single-dose vaccine, which was to be introduced in India through a supply agreement with Biological E; and it had authorised Indian pharma company Cipla to import the Moderna vaccine. SAGE/WHO: A booster dose should be given 4-6 months after the primary series* and a second booster after 4-6 months for specific population groups**. Studies to investigate whether this vaccine reduces SARS-CoV-2 transmission and viral shedding. No cases of severe fever were reported, and total fever rates were 4% or less after the second dose [Vadrevu KM, 2022 ].

IMDG is a novel, Studies generally demonstrate that TLR 7/8 agonists enhance Th1 responses and inhibit Th2 responses which is considered beneficial for COVID-19 vaccines. SAGE/WHO: Comirnaty (Pfizer-BioNTech) combined with any other EUL COVID-19 vaccine is considered a complete primary series. SAGE/WHO: Extended primary series with an additional (third) dose 1-3 months after the second dose, and two boosters (fourth and fifth doses) given 4-6 months after the previous dose. GBS has been reported very rarely (i.e. The majority of respondents received AstraZeneca (51.1%) and Sputnik (37.6%). The Hyderabad-based firm also said data from the clinical trials have been submitted for approval to the National Regulatory Authorities (NRAs), the gatekeepers of the supply chain of medical products. Get back your reporter Shahaz Ansar. According to PRAC/EMA, there is currently insufficient evidence of a possible link between Comirnaty and very rare cases of multisystem inflammatory syndrome (MIS) [15]. BBIL/BBV152-A/2020 was a phase 2, randomized, controlled, trial in India, in which 184 vaccine recipients were included. About 80% of eligible adults have been fully vaccinated and more than 99% have received at least one jab so far. There is no available data on booster doses beyond the third dose. Purified inactivated viruses have been traditionally used for vaccine development and such vaccines have been found to be safe and effective for the prevention of diseases caused by viruses like influenza and poliovirus [Gao Q, 2020 ]. It was also a pathbreaking initiative because, at that point, the two other vaccines in the market one by GSK and another by Merck were priced several times higher. Monodose (0.5 mL) or multidose vials of 3 doses (1,5 mL). The Bharat Biotech COVID-19 vaccine (BBV152) is a whole virion inactivated SARS-CoV-2 antigen adsorbed to alum and formulated with a toll-like receptor (TLR) 7/8 agonist Imidazo quinolin gallamide (IMDG) and the preservative 2-phenoxyethanol [ WHO, 2022 ]. Subgroups The vaccine was the result of a tie-up between the Department of Biotechnology and Bharat Biotech. 'Ready to use' formulation: multi-dose vial (0.3 mL each). Administer the vaccine intramuscularly, preferably into the deltoid muscle. When the vaccine was announced in 2011, it just so happened that. Which means that 500 people need to receive the vaccine for one of them to not contracting severe COVID-19. Two doses (0.5 mL) 3 weeks apart, followed by an additional (third) dose provided 4 weeks after. Multidose vials of 2, 8 or 10 doses (0.5 mL each). Vial volume: 2.5 mL. The relative risk of systemic adverse events after the 1st dose in the group that received Bharat Biotech COVID-19 vaccine, versus the group that received control vaccine was 1.34 (95% CI 1.14 to 1.58). Although the cellular response can be elicited by many vaccines, protection against subsequent coronavirus infections is largely mediated for humoral immunity. Neutralizing antibodies against homologous and heterologous SARS-CoV-2 variants increased 19- to 97-fold after a third vaccination[Krishna Mohan Vadrevu, 2022 ]. The emergency-use nod doesn't mean India will immediately start vaccinating children younger than 12 - that can only begin once the National Technical Advisory Group on Immunisation gives a green signal. However, a heterologous scheme using a second dose of an mRNA vaccine may be more immunogenic and effective. However, the report made it clear that efficacy cannot be determined by phase 2 trials and this required further corroboration with phase 3 safety results. Vaccination logistics Omicron (B.1.1.529)BBIL/BBV152-A/2020 was a phase 2, randomized, controlled, trial in India, in which 184 vaccine recipients were included. [Srivastava RK, 2021 ]; Singh et al. The study showed a fold increase of 2.8 (95% CI 2.65 to 2.95) in anti-S1-RBD IgG GM titers between the 2 dose and booster dose groups and a fold increase of 16.54 (95% CI 34.08 to 8.03), p<0.0001 in NAbs titers against Delta variant between the two groups [Deshpande GR, 2022 ]. was a cohort study conducted in India. Children <12 years were excluded [Ella R, 2021 ]. ALSO READ | Explained: As India Unveils SII's CERVAVAC, Know How Cervical Cancer Vaccines Work. When the vaccine was announced in 2011, it just so happened that paediatrician Dr M.K Bhan, whose team in AIIMS had isolated that strain, was the secretary in the central governments Department of Biotechnology.
