Covaxin vaccine from Bharat Biotech in India is found to be 81% effective at protecting people from coronavirus in clinical trials. India's first Made in India vaccine for coronavirus will play a major role in India's effort to produce enough vaccine to vaccinate 1.2 billion people. With enough vaccine supplies coming from many Indian pharmaceutical makers who will now have access to Bharat Biotech's science and vaccine making technologies. The Indian government has stepped in to coordinate this effort. Covaxin and Covishield will play a major role when new vaccine supplies come into the field in July to December 2021. The target is to vaccinate 1.2 billion people by December 2021. This is an important moment for Indian science in the field of medicine.

Bharat Biotech and Biological E. are two companies developing vaccines in India. Bharat Biotech has asked for emergency authorization for use of its vaccine. Other Indian companies that have asked for emergency authorization are Pfizer India and Serum Institute of India. The foreign envoys will be flown to Hyderabad to be briefed on the vaccine readiness at Bharat Biotech and Biological E. In all 30 of 100 vaccines under development are being developed in India. India is a pioneer in vaccine development and manufacturing. Because of its huge population of 1.5 billion for India and Bangladesh, India has from the early years after independence in 1947 pursued a course of developing its own R&D and manufacturing of pharmaceuticals and vaccines, so that the large population can have access to medicine at a low price.

India plans to vaccinate 300 million people in the first drive of the vaccination campaign. The two vaccines approved are the Covishield from Astra Zeneca partnership with Serum Institute of India, and the Bharat Biotech vaccine. India is the largest vaccine manufacturer in the world, and its vaccination production and campaign is being watched closely.  The largest maker of vaccines is Serum Institute of India based in Pune. Countries that are seeking India's help in vaccines are Brazil, South Africa, Morocco, Saudi Arabia, Bangladesh. Brazil has ordered 1.5 million vaccine doses. The Indian government has approved sending vaccines to other governments. Price of 100 million doses to be supplied by Serum Institute to the Indian government is 200 rupees a dose or about $2.73 a dose. Vaccine sold in private markets will be priced at 2000 rupees a dose. Serum Institute and Bharat Biotech have stockpiled 70 million doses. ...

Bellman and Dayal in WSJ give this amazing report of how vaccine travels from Pune to remote region of Mizoram hills in India's northeast near Burma. This is the story of the largest vaccination drive in the world that aims to have the vaccine supplies by July to vaccinate the entire population of 1.2 billion people by December 2021. It all began with Oxford University and Astra Zeneca with the decision to make the vaccine available to such a vast population and to people in all parts of the world not just Europe and the US. Bharat Biotech and India's pharmaceutical manufacturers have now joined efforts with the help of the Indian government to produce enough vaccine at affordable cost and make vaccine supplies ample and accessible. This will then be extended to all parts of the world.

The Oxford vaccine manufactured and distributed by Astra Zeneca faced manufacturing problems in 2020. The company is fixing these manufacturing problems and plans to meet demand from Britain, the European Union, and the rest of the world. It plans to double vaccine monthly production to 200 million doses monthly by April. CEO Pascal Soriot says "Is it perfect? No, it's not perfect, but it's great, and tell me who else is making 100 million doses in February?" The Oxford vaccine has shown strong protection against severe coronavirus symptoms and is important in the fight against the pandemic. To tackle variants of the coronavirus the company plans to have another jab developed by autumn this year.

Britain and India are depending on Oxford vaccine to vaccinate large parts of the population. India has a second vaccine developed by Indian scientists at Bharat Biotech that is also in use.

Peter Hotex of Baylor Medicine in the US is a pioneer and leader in getting low cost traditional vaccines to billions in Africa, Asia and Latin America.  Here Peter Hotez of the Baylor College of Medicine Tropical School is interviewed in The Hindu. He talks about how the new mRNA vaccines are "shiny toys" pushed forward in the US in 2020 under innovation drives, and that the vaccines made by traditional methods are just as effective and provide lasting protection. Without vaccinating the entire world population including the billions of people living in Africa, Asia and Latin America, there will be no end in sight for the pandemic, he says, and the best way to do this is through vaccines made by traditional methods, methods used by Bharat Biotech for Covaxin and Biological E for its vaccine. He said mRNA is a brand new technology  and "it will take years to scale it up to make 9 billion doses" of vaccine for poor countries. Baylor has developed the vaccine technology using traditional methods such as yeast fermentation expression technology used for Recombiannt Hepatitis-B vaccine. Its been around for 40 years. Baylor will transfer the technology to Indonesia, India, Bangladesh, all over the world. He says in terms of virus neutralizing anti-body immune responses it is as effective as the mRNA vaccines. Hotez is critical of some pharma companies- "the rest of them want to bicker about patents. we're not going to go down that direction." Baylor is providing its technology for manufacture to companies to fill the need in poor countries, without patent protection or quibbling about legal things such as indemnities, says Hotez. Hotez also thing recombinant protein technologies vaccine with its traditional approach could also overcome vaccine hesitancy, a key factor for unvaccinated in Europe and US which have stuck to mRNA vaccines. The newer technology behind mRNA could make parents hesitate to vaccinate their children with these technologies, and also be a part of the mental attitude of unvaccinated adults having hesitancy.   ...

A major British and Indian collaboration and scientific achievement of both countries is not given the recognition it should get because of mismanaged communication of the results of clinical trials. Tom Whipple science editor of The Times says do not make the mistake of thinking oh Pfizer vaccine scores a 9 out of 10 and Oxford's a 7 or 8 out of 10. Pfizer vaccine says it 94% effective. But this is only part of the story. It is the first exam paper in a long number of exam papers and the final score will require scoring them all. "Oxford vaccine is complex, and we are happy with the complexity," says Adrian Hill, Oxford researcher and head of the Jenner Institute. It is not highly unusual in this complex field for a half first dose to work better than a full first dose in a two dose vaccine treatment. This happened with the Oxford vaccine. As a result the study results were harder to communicate. This happened by accident. Much of medical research and much of medicine's biggest breakthroughs in the last 200 years happened by accident, as one researcher looked for something and accidentally discovered something else profoundly useful. Whipple's points are turning out to be true now that Britain's medicine regulator has asked that Pfizer vaccine not be given to people with history of allergic reactions after 2 NHS workers had strong allergic reactions. A lot of questions remain for all vaccines. How long will the protection last? WIll it prevent transmission of coronavirus? Are there any other complications? Which vaccines can work without ultralow refrigeration storage? Ahead lie the prospect of billions of doses. Two are in final stages in India including Bharat Biotech request for emergency authorization. Johnson & Johnson has a competing one to Pfizer's in the U.S. As many as 30 are being developed in India and 100 around the world. Countries like South Korea say they will wait to find out which one works best and where cost overall combined with benefit is attractive. Some of the vaccines are coming out only weeks apart. The early ones could stumble, if something was missed. ...
