By 2022, there is a plan to make an mRNA-technology vaccine, for which it has tied up with Canadian firm Providence Therapeutics.
'The key purpose of vaccination is to prevent hospitalisation, severe disease, and death.' 'All vaccines work equally, although mild disease cannot be prevented.'
We have applied for marketing authorisation to the EMA through AstraZeneca. We will not sell the vaccine in the EU, said a company source.
While Bharat Biotech's Covaxin is in trials among children already, Serum Institute of India will begin Novavax vaccine trials on children from July, whereas the Pfizer vaccine has been approved for adolescents in the United States; and Cadila Healthcare's ZyCoV-D has done trials on 12 year-olds and above already, reports Sohini Das.
865 million Indian adults require vaccination.
While virologists say theoretically the vaccine that works on Delta should work on the Delta Plus variant as well, more research is needed.
The Covid-19 vaccine demonstrated an overall 90.4 per cent efficacy in phase 3 clinical trials, reports Sohini Das
This could also be India's first vaccine for children aged 12 years and above as the company has conducted trials on the age group. The decision, however, lies with the regulator, reports Sohini Das
According to medical practitioners, the treatment is especially useful in controlling disease among those who have not received the vaccine or got only one shot and also the high-risk contacts of a patient.
Raches Ella, project lead, Covid-19 vaccines at Bharat Biotech said in a series of tweets that he was 'surprised' that media and researchers were drawing conclusions based on non-peer reviewed work.
'Almost 70 per cent production time of a vaccine is dedicated to quality control, which is done through several hundred tests.'
The study by a group of doctors showed that after two shots of the vaccines, 98 per cent recipients of Covishield showed antibody response, while the same was 80 per cent among Covaxin recipients. Sohini Das and Ruchika Chitravanshi report.
Providence will sell up to 30 mn doses of its mRNA vaccine to Biological E. It would also provide the necessary technology transfer to make the vaccine in India, with a minimum production capacity of 600 mn doses in 2022 and targets capacity of 1 bn doses, reports Sohini Das.
500 million doses per annum from its two sites in Hyderabad and 200 million doses each from its Ankleshwar and Kolar facilities.
Commercial launch and supply to major government and private hospitals is expected in mid-June.
Pune's Mylab Discovery Solutions' CoviSelf, which gives results in 15 minutes, gets ICMR nod
However, Cipla was very clear it does not want to get into vaccine manufacturing.
This apart, to further increase capacities, Bharat Biotech has partnered with Indian Immunologicals (IIL) to manufacture the drug substance for Covaxin. The technology transfer process is underway and IIL has the 'capabilities and expertise' to manufacture the inactivated viral vaccines at commercial scale.
India expects 2.16 billion doses of Covid-19 vaccines between August and December, including the jabs that are currently in clinical trials, reports Sohini Das
Apollo Hospitals and Fortis Healthcare are open to importing vaccines.
