Kate Bingham, head of the Vaccine Task Force in Britain is commended for her intelligent approach in placing bets on vaccines in different technologies, "four buckets" as she calls them. This includes the Moderna and Pfizer in the mRNA technology and the viral vector Astra Zeneca, J&J vaccines. This approach made the British vaccination drive effective by being supported by a resilient supply system.

The Indian government has supported the effort to get several companies to make the Sputnik Russian vaccine in India in an effort to diversify supplies. Reddy Labs is one of the major manufacturers working on the Sputnik vaccine in 2021.

Pfizer says a third dose of Pfizer vaccine neutralized the Omicron variant in lab tests. The two dose was much less effective at blocking the virus. A third dose increased antibodies 25 fold compared two doses for the omicron variant. Pfizer CEO Albert Bourla says- "Although two doses of the vaccine may still offer protection against severe disease caused by Omicron strain, it's clear from these preliminary data that protection is improved with a third dose of our vaccine."

A conflict is developing between Britain and the European Union over vaccine supplies as both sides try to get access to limited supplies. Britain and the US have moved ahead with their vaccination drives, causing alarm in Europe as Germany, France, member states of the EU lag behind. The problem comes from the delay in approving the vaccine by Astra Zeneca and Oxford University by the European Union. European Union prestige is at stake because its slower process of approving vaccine has led to a delay of 1 month in approving the Astra Zeneca vaccine. The Oxford vaccine is only now approved in Europe. Other problems have emerged. Astra Zeneca has announced that its vaccines made in Britain are now running short of supply and it can only provide 39 million doses to the EU instead of the 80 million originally arranged by EU. Soon after this announcement Pfizer said its factory in Puurs, Belgium, near Antwerp, is running into production issues. This would reduce supplies to the EU.  The EU has responded to this situation by saying it was being treated unfairly by Astra Zeneca. In response it has introduced new paperwork that would limit supply of Pfizer vaccines to Britain from the Belgian plant. Other countries are watching this situation with dismay as richer countries are fighting for the vaccine supplies. ...

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. ...

Estimates that about 161 million people have been vaccinated in China with Sinovac vaccine made in China. That vaccine has effectiveness of 50.1% at preventing symptomatic infections, as estimated by researchers in Brazil. This compares with the newer technology used in Pfizer and Moderna vaccines that have effectiveness of over 90%.

Most questions about the vaccines from Oxford, Pfizer and Moderna are answered in this Q&A in The Times.  The Oxford vaccine is the only vaccine that is being provided at cost to the public at a cost of 4 pounds, Pfizer using German technology at 15 pounds and Moderna from Cambridge, Massachusetts, at 28 pounds. The Oxford vaccine can be stored in a fridge, the others use mRNA technology of messenger RNA which requires ultra low temperature storage. Astra Zeneca could have handled the trials and methodology for results in a better way. As the two trials one that produced results of 62% and the other results of 90% cannot be combined to give results of 70% but are two distinct and separate trials. However too much emphasis has been placed on the vaccine, as other prevention measures remain important for 2021. Other vaccines are being developed in Britain with new technology and in India by ICMR which are in trials stage and about which not enough is known. The Russian and Chinese vaccines have not released detailed data limiting their use around the world. ...

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.

The Oxford vaccine is showing promising results and is expected to be authorized for use by December 2020. The vaccine being developed in partnership with Astra Zeneca PLC for marketing and Serum Institute of India for mass manufacturing is shown to be proven 90% effective in preventing infections in clinical trials. The partners say there were no serous safety events and the vaccine has proven 62% to 90% effective with an average of 70%.  This vaccine is significant because it is being developed with this partnership not seeking profits from this venture, providing it at cost and keeping the price to about $4 a dose compared to competitors Moderna and Pfizer whose vaccine is expected to be at $24 a dose. The Oxford vaccine also uses existing technology for vaccines and manufacturing is being done in India with the world's top manufacturer of vaccines. By using existing technology unlike the Pfizer and Moderna technology Oxford has taken an approach that could prove to be unique by minimizing side effects for vaccines that are being developed with such speed. By not requiring refrigeration at very low temperatures the vaccine makes itself ready for immediate and widespread uses all over the world. By use in its home country India with its large population Oxford vaccine can gain even wider acceptance because of India's long experience in pharmaceutical technology and manufacturing. Of particular interest is the study of 23,000 participants showing that the 90% effective dosage is one that only requires half a dose for the first shot. This say scientists is because the vaccine first dose prepares the body for a more powerful second dose and creates the maximum effect. This means the vaccine can be used for more doses than 2 full doses. It can be stored in a fridge making it easy to use in many countries. The full study will have 60,000 participants spread across U.S. Britain, Brazil South Africa and India. ...

This report in the WSJ shows Pfizer is expected to make $8 billion in profit on its vaccine business, and Astra Zeneca barely breakeven in the vaccine business. The British-Swedish drugmaker Astra Zeneca had offered to distribute the vaccine at no profit during the pandemic. For this reason Astra Zeneca is the only vaccine that is available in 170 countries with 1 billion doses released. One of the main recipients is India with a population of 1.2 billion, which is also a vaccine maker for the Astra Zeneca vaccine that was developed at Oxford University, under Indian brand name Covishield. The Pfizer vaccine by contrast was sold to governments in the US and European Union, and Britain, who could afford the large outlay of funds and signed contracts early.

With better control over the coronavirus than U.S. and Europe, South Korea is not rushing to buy the vaccines developed by Pfizer or Moderna. It is waiting to see how the vaccine rollouts work in other countries before buying the vaccine. South Korea is also looking at getting better price from manufacturers after the rollouts in the U.S. and Europe. South Korea is moving cautiously and has said it wants to get 10 million doses through the Covax initiative the main global effort to provide broad access to vaccines. Another 20 million doses would be secured from private companies. This is in contrast to the approach in Japan where the government has signed deals for purchase of 290 million doses for 145 million people for its population of 126 million. The money allocated is $6.5 billion and the goal is to vaccinate everyone by first half of 2021.  If it works this would prepare Japan for the Tokyo Summer Olympics to open in July, after 1 year delay. South Korea has the freedom to do this and wait to see what vaccine works best with least long term effects because their are relatively fewer cases there. A total of 313 new daily cases on November 18, lower than daily cases in a single county in the state of Michigan in the U.S. Moderna and Pfizer vaccines use anew kind of gene based technology that has never been approved to prevent infectious diseases. Other competition is the vaccine from Oxford and Astra Zeneca which uses an existing technology that is used in existing vaccines modified for use in coronavirus. The Oxford vaccine and a vaccine from Johnson and Johnson are expected to have a lower price. Because life is functioning very close to normal South Korea is in the unusual position of saying that its people have no reason to be anxious for vaccine procurement, as indicated by its deputy director of Korea Disease Control and Prevention Agency. Only three fifths of the population is the target for vaccination by fall of 2021. ...

In this interview in The Hindu with Public Health Foundation of India president Srinath Reddy, the importance of safe behaviours including masks and social distancing, public discipline to tackle a potential third wave. This was also pointed out separately by the Director AIIMS.  Mr. Reddy says study by Public Health England shows just one dose of Astra Zeneca vaccine is not very effective against the Delta variant- about 30% effective. As a result he suggests the need to reduce the spacing intervals which are at 8-12 weeks to a shorter interval now that adequate supplies of vaccine will be available starting in July and August till the end of the year. The initial spacing was 4 weeks when Astra Zeneca vaccine was first introduced and at which time the variants had not emerged. The Indian federal government affidavit to the Supreme Court shows that 1880 million doses of vaccine will be available by the end of the year 2021 to vaccinate fully with 2 doses the population of India over 18 years using 5 locally manufactured Made in India vaccines. This does not include the mRNA vaccines that will be made available from Moderna and Pfizer for which cold storage facilities are being prepared by the federal government.   ...

The true story of the two German scientists, children of immigrants from Germany, who did the research behind the Pfizer vaccine for coronavirus. One the son of a guest worker from Turkey who worked at a car factory in Cologne, another the daughter of a doctor who finished medical school and immigrated to Germany. They started primarily on cancer vaccines using new mRNA technologies. Much of their work focused on meeting the gap that had developed says Ozlem Tureci, between what was done in the labs and what was available to patients and doctors.

Germany's National Prize awarded to Ozlem Tureci and Ugur Sahin for BioNTech Covid Vaccine.  "You both embody the future strength of a liberal society. As scientists who seek solutions. But also as entrepreneurs for whom responsibility is at the center of their work." Merz says during the award ceremony in Berlin. The chancellor praised Türeci and Sahin, with their Turkish roots, giving examples of how "skilled labor immigration can be a driver of progress." "I want to live in a Germany in which talent is promoted to the best of our ability, regardless of social or ethnic background." ...

In a bold decision that shows courage and foresight president Biden lifts IP protection for Covid 19 vaccine patents of American companies such as Pfizer, Moderna, J&J and Novavax. This has huge implications for vaccination supplies for countries such as India, Indonesia, Brazil, Mexico, that are hard hit by the pandemic as well as the rest of the world. It will open up manufacturing additional vaccine supplies in countries as diverse as France and India, that can ramp up quickly because of already established pharmaceutical bases.

The Hindu data team looks at the Indian vaccination drive with graphs by state and progress by dates. During the first 10 days of June the vaccination drive has been stepped up. It is now over 3 million a day and at this rate should reach 400 million vaccinated by the end of July, 100 million below target. For the remainder of the year vaccine supplies have to be pushed up so that 8 million doses can be given each day. This would get India to where everyone in the country of 1.2 billion has been vaccinated by Dec 31, 2021. This would make it possible for India to then use its technology and large manufacturing capacity to help other nations in Asia, Africa and Latin America in 2022. This is the first time in history that India has taken on a challenge of this size and complexity. The vaccine strategy has changed to where the federal government is taking over the overall responsibility of coordinating the production of vaccines in the country and providing access to vaccines from other countries. Federal government is also taking on overall responsibility for distribution of vaccines and setting up the logistical effort. Vaccine supply is being opened up by opening India to multiple vaccines including Pfizer, Moderna, and other vaccines. Production of Covaxin is being stepped up. This strategy is designed to get India to somewhere closer to the 8 million doses a day needed and to ensure distribution and logistical efforts are in place. More resources are put into the effort. The speed of economic recovery also depends on the vaccination drive. Lessons were learned during the second wave in May 2021 and the government is better prepared for the hard work ahead. ...
