Pfizer coronavirus vaccine is shown to be 90% effective in results from Phase 3 trials. The findings come from a preliminary look at the first 94 infections in a group of 44,000 people in the trial. The vast majority of the cases received a control instead of vaccine. A vaccine is considered effective if it works on 50% of cases. The Pfizer vaccine is based on an experimental "mRNa" technology.

Britain has ordered 5 million till the end of 2020 and another 20 million for 2021. In total Pfizer plans to make a billion doses of the vaccine by 2021.

EU Commission president Leyen announces Pfizer will supply EU with 1.8 billion doses of Pfizer vaccine to 2023. The increased supplies will include booster shorts to increase immunity. Another change is the new date for 70% of European Union population to be vaccinated, which is now advanced to end of July instead of end of September. With new waves of the coronavirus affecting Europe, and criticism of the EU's earlier effort in securing vaccine supplies, more urgency has gone into the new effort in 2021. Leyen told Pfizer CEO Albert Bouria- "If I may say so, engineer the mRNA in a way that it can adapt to potential escape vaccines," at a joint press conference. Leyen thanked Pfizer for its enormous effort in boosting vaccine manufacture and delivery. This will help accelerate the vaccination effort in Europe after the slow start in March and April of 2021. Bringing much needed optimism and new hope of a lasting recovery both in economic activity, health and in the mood in Europe, which can then spread from the US and Europe to the rest of the world. ...

British regulators say they have"absolute confidence" in the Pfizer vaccine after analysis of over 1000 pages of data on the vaccine. The vaccine was approved by the Medicine and Health care products Regulatory Agency. The first vaccines to be shipped to Britain are being packed in Belgium. Britain has secured 40 million doses enough for 20 million people. Vaccination will begin as soon as doses reach Britain. The NHS will prioritize, first care home staff and residents, then healthcare workers, followed by people over 80 years age. Clinically vulnerable people will get a jab alongside people ages 70-74. People with severe obesity and underlying conditions will get jab after people over 60 years, followed by people over 50 years. About 34% of the 66 million population of Britain is over 50 years age, which is about 22 million. This means the Pfizer vaccine ( with doses already secured by Britain enough for 20 million people) covers over 90% of these people or 19 million people and the 1.1 million workers in NHS. Rapid progress in vaccinating these people would make Britain the first country in the world to have done this, a remarkable achievement. By the end of the year the Oxford vaccine should also be available making it possible to proceed with vaccinating the rest of the population of 46 million people. ...

As Pfizer prepares shipments of 25 million doses of vaccine in the U.S. this WSJ report looks at how Pfizer CEO Albert Bourla pushed his manufacturing managers to the limit to increase production. He wanted 100 million doses for 50 million people by the end of 2020, production would have to be ten fold what the initial targets were. Pfizer will achieve half that which is an achievement considering how much had to be done. This report looks at the development of the vaccine at Pfizer since the early days in March when the collaboration with BoNTech in Germany began.

Protection from hospitalization for Omicron variants can drop to 57% from 81% after 6 months from second dose, and can be pushed back up to 90% using booster shots for Pfizer and Moderna vaccines, according to a large CDC study in the US. For Delta variant period last year the vaccine effectiveness against hospitalization was 90% from about two weeks after dose two till 6 months, dropping to 81% after 6 months, and up to 94% after a booster shot. For Omicron variant the currently vaccine effectiveness for same periods is 81%, 57%, and 90%.

The experience of J&J and Novavax in vaccine manufacturing shows the importance of vaccine manufacturing and of Quality Assurance in the production of vaccines for coronavirus. The success of Pfizer and Indian companies in vaccine manufacturing shows how important it is to think early and plan early for vaccine manufacturing technologies, personnel and quality assurance. This is also why the US effort, India's billion vaccine target in 6-12 months of planning, is a great effort in thinking ahead of every aspect of vaccines and vaccinating, planning of all details, hard work, by Pfizer, by Indian pharmaceutical companies, and by the Modi and Biden administrations.

Pfizer's Covid vaccine is expected to bring in $6 billion in profit in 2021. Pfizer increased its sales forecast by 70 percent. The coronavirus vaccine is expected to bring in $26 billion in revenues in 2021 with 1.6 billion vaccine doses manufactured for the year 2021. The total could be much higher with the company striving for supply contracts to manufacture 2.5 billion doses.

India has approved the Pfizer, Moderna and J&J vaccines, with this bringing American companies into the Indian vaccine market in 2021.

With more vaccines available from Pfizer and Moderna, and the poor SinoVac Chinese vaccine effectiveness against the Delta variant, Brazil and other countries in Latin America and Asia are shifting away from Chinese vaccines. Brazil's federal government has halted negotiations for additional doses of Chinese vaccines. In the early stages in 2020 Chinese vaccines helped Brazil cope with the devastating rise in cases. The slow pace of vaccinations in US and Europe has freed up more vaccine doses of Pfizer for other countries including Brazil. From accounting for 80% of vaccines in Brazil early in 2020, SinoVac vaccines now make up only 35% of Brazil's vaccine doses. At that time Brazil bought 100 million doses of SinoVac vaccine which were delivered. The local producer of SinoVac vaccine, the Butantan Institute will no longer make Chinese vaccines. While Sinovac vaccines are effective at preventing deaths, the vaccines have a low effectiveness rate for symptomatic infections. ...

The Oxford vaccine is shown to be effective for older adults over 70 years in age. One of the key features of the Oxford vaccine is that it is designed to be accessible in cost for not just high income countries but across all parts of the world including the countries in Asia, Africa and Latin America where some of the poorest people live. The cost will be a fraction of the cost of the Moderna and Pfizer vaccine. Results for regulatory approval are expected by Christmas. This vaccine is expected to cost about $4 a dose compared to $25 for the Pfizer or Moderna vaccines. Oxford also uses a technology for the vaccine that has already been proved effective with least side effects fr other virus such as Ebola virus. Oxford researchers took the existing vaccine technology and modified it to tackle coronavirus in a way that proves effective for this virus also. Countries such as South Korea say they will not rush into the first vaccine that is available and have not responded to requests for sale from Moderna or Pfizer. India's Serum Institute is the leading manufacturer of vaccines in the world. It is preparing for production of the Oxford vaccine. India's vaccine effort includes other vaccines developed by its research institutes. The focus of India is for a vaccine that is effective as well as meet cost so that it can be used to vaccinate over 1.3 billion people. Because India has strong already established manufacturing capabilities for vaccines and is collaborating with Oxford and Astra Zeneca for a low cost vaccine it is in a position to drive the campaign for an effective plus low cost 100% accessible vaccine for people around the world. Another aspect of the Astra Zeneca partnership with Oxford is that it has committed not to make a profit from the vaccine. This is important for Oxford researchers and its organizational goals. ...

There are 100 vaccines being developed all over the world, of these 30 are in India. One is a collaboration with Britain for the Oxford Astra Zeneca vaccine to be produced largely in India. The other is one by ICMR. Other vaccines are the Johnson and Johnson  one dose onl vaccine. These vaccines have the advantage of not requiring ultra low temperature storage. 

Even though the Pfizer BioNTech vaccine is off to a start in Britain this does not mean that the other vaccines are not going to be out soon as early as by the end of December. There is also no clarity on how long the protection lasts. More than the one billion doses of the Pfizer vaccine will be required making the other vaccines just as or even more important. Asia and Latin America, Africa are still not in the picture and will have to be for the protection to be effective.

Pfizer and Moderna's plans to make mRNA vaccines in Africa, Asia or Latin America may take much longer than 2022. The solution to producing an mRNA vaccine in Asia that could be mass manufactured and distributed throughout Africa, Asia and Latin America is now at hand. Gennova based in India, is partnering with Seattle startup HDT Bio to attack the problem of temperature and scalability in manufacturing for a mRNA vaccine that acts as a global solution using India's manufacturing capabilities. Dr Singh who founded Gennova, says- "We wanted to solve the problem of the scalability issue, and the temperature issue. If we can solve these problems, we are building a solution not just for India, but also a global solution." Gennova received seed funding from the Indian government. Other companies in Brazil and South Africa lack the manufacturing capabilities or financing needed that exist in India. The Indian government has achieved an initial goal of one billion vaccinated in just 6 months. The next step for India in its health infrastructure buildup is a mRNA vaccine that is an improvement over Pfizer and Moderna vaccines that can be stored easily, adapted for variants, and manufactured in large quantity as a global solution. ...

After a good start the vaccination drive is slowing both in India and the US. Vaccine supplies need to be boosted in India and the government has given approval to the Pfizer, Moderna and J&J vaccines to boost supplies. The Sputnik vaccine from Russia has also gained approval with new supplies of that vaccine expected in India. Vaccine skepticism is a problem in the US and Europe. Supplies of the Pfizer vaccine will be boosted in Europe with the EU contract for 1.8 billion doses signed recently. This should give the slow vaccination drives in France and Germany a boost.
