Moderna has made the initial batches of doses of the vaccine for the variant of coronavirus including South African variant, and shipped these to the National Institutes of Health in the US. If the test results are positive the vaccine for variant could be given authorization by the third quarter of 2021. It is becoming crucial to stay ahead of variants developing from the coronavirus and pharmaceutical companies Pfizer, J&J, Astra Zeneca are working on the technology to tackle this.

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 US has not yet approved the Astra Zeneca vaccine. Yet the US sits on large supplies of the Astra Zeneca vaccine. Europe badly needs the vaccine with its failure to procure enough vaccine doses. This is one of the paradoxes of the situation today. Italy faces a lockdown by Easter. 70% of cases in France are now variants, says the Health Minister Olivier Veran, and ICU's are 80% full. In Germany there are fears of a third wave. Yet vaccine supplies remain low and vaccination drives in Europe are slow, creating much frustration for the people.

China faces risk of a surge inthe coronavirus in June 2021. The area in and around Guangzhou appears to be seriously affected. The city tested almost its entire population of 18.7 million between June 6 Sunday and June 8 Tuesday. This report shows pictures of a deserted Beijing airport, strict restrictions on foreign travel. The SinoPharm vaccine effectiveness against the Delta variant in India and UK is unknown. The government is locking down entire neighborhoods rather than entire cities or provinces.  As the risks of the Delta variant and other new variants increases most of the population even in the US and Europe have either no dose or one dose. Researchers at the University of New South Wales in Australia show the Astra Zeneca vaccine effectiveness with one dose at only 30%, only after two weeks following the second dose does the vaccine effectiveness reach about 70%. The population of China and India are so large that much larger parts of the population remain unvaccinated. In China with 1.3 billion people and even if the figure of 800 million doses stated by the government is accepted- it could be an overestimate as the US has only managed 300 million doses with many vaccines- most of the population is unprotected. Vaccine skepticism is high in China making vaccination an uphill task. SinoPharmvaccine is not as effective as Pfizer, Moderna, Astra Zeneca, or Covaxin vaccines, making the task even more of an uphill kind. ...

The third or booster dose of vaccine is needed to take out the Omicron variant. The UK Health Security Agency analyzed data from 581 Omicron cases and thousands of Delta cases to calculate how effective vaccines such as Pfizer and Astra Zeneca were against the Omicron variant. This early analysis shows a third booster dose prevents around 75% of people from getting any coronavirus symptoms. The double dose of the vaccine however provides good protection against severe coronavirus that needed hospital treatment says the UK Health Security Agency. Of equal concern is the rate of spread of the Omicron variant. Here this BBC report shows graphs of UK National Health Security Agency which show the rate of spread is rapid with cases doubling every 2-3 days. For the UK which on December 10 had about 1265 cases this means says this BBC report that the number of Omicron cases could be well above 100,000 in the UK by the end of December. The BBC graph shows the curve for Omicron cases moving in a close to vertical direction upwards. Reports say the experience in South Africa where the Omicron variant was first detected is similar in pattern causing rapid spread. ...

Jenny Strasbourg of the WSJ provides this much needed report from London about the courageous decision by AstraZeneca and Oxford University to give vaccines away at no profit to the whole world, to billions of people in Africa, Asia, and Latin America. Without this brave decision by a British company and a British University the world would be a lot poorer, more variants could have happened, making us realize the great contribution Britain has made and how indispensable it is to the planet. Add to this the effort of Indian companies including Serum Institute that provided the manufacturing facilities and capabilities for making most of the British vaccine. AstraZeneca delivered 2.3 billion doses of the vaccine globally as of mid-December, according to the company. The International Monetary Fund estimates that low and middle income countries received 3.25 billion vaccines as of Dec. 11, About half of this or 1.6 billion doses were Astra Zeneca shots. This is a bigger share than any other vaccine by far and a life saver to the world. AstraZeneca stepped up early in a true to the best ideals in Britain to meet the needs of the world-  aiming to deliver 3 billion doses in 2022 and sell them at no profit as long as the pandemic continues. As the shot does not need cold storage it is ideal for India and other Asia, Africa and Latin America. "We are all very proud throughout the company of the impact we have had," says AstrZeneca CEO Pascal Soriot. By far the biggest manufacturing was done at Serum Institute of India which supplied 1.3 billion doses of the AstraZeneca vaccine to 70 countries. Mr. Modi pushed forward the export of vaccine made in India to the world from the beginning in the same spirit of cooperation and the best ideals that Britain was living upto. Serum Institute can produce as much as 250 million doses of vaccine a month making it possible for India to tackle the vaccination population of 1.3 billion people.   None of this could have happened without Oxford University and AstraZeneca and Indian companies with Mr. Modi's active support living up to the best ideals of Britain and India for the world. "When you add up the benefits to humanity, I think you'll find the vaccine holds up pretty well in terms of the ill health it has prevented, and the deaths it has prevented," says John Bell, a senior Oxford academic who in 2020 guided the University through its vaccine-partnership talks with Astra Zeneca. Because in the real world AstraZeneca shot has held up so well it is also a choice for booster shots. ...

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.
