The best and the worst vaccines available at this time

 The best and worst vaccines available at this time.

The Chinese have the worst vaccine with a 50% efficacy rate in five or six candidate data published after phase 1 to phase 3 trials. Yet they claim they almost wiped out the virus after they invented it in Wuhan's laboratory (not likely to be true). To date, the best vaccine with 95% efficacy rates is an American Pfizer vaccine followed by an American Moderna vaccine with 90-92% efficacy rates. If anyone was successful in eradicating the Wuhan virus, it would be the United States. But for the rest of the world to use the U.S. vaccine is to create a super cool refrigeration unit to keep it frozen at -75C until ready to use. Only the US has the money to install super cold refrigerators in hospital and clinics. Europe may be the next best candidate, which is using both American vaccines.

The interesting part about using or licensing producing it in India is that Pfizer wants interested countries like India, Brazil and others to hypothecate their military assets to them as collateral. No country is willing to do that, so the use of this vaccine will be in the U.S., in Europe, and to some extent in Canada.

The Indian vaccine a license produced in the Serum Institute in Poona is the AstraZeneca vaccine developed in the United Kingdom is a reasonably good vaccine with an efficiency rate of 80%. It does not require super cool refrigeration. It's good for middle-income and poor countries. That is where it is used.

The Indian locally developed vaccine at Hyderabad and given Covaxin as a commercial name is better than the AstraZeneca vaccine, which even the US, famous or infamous Dr. Fauci has given Covaxin a huge endorsement recently. Following complete approval, India will use this AstraZeneca (Covesheild) and Covaxin intensively both in India and exported. Right now these have been granted emergency use approvals.

The Russian vaccine now will be used in India during the vaccine shortage is a great candidate with an efficacy rate of 90%. However, it is not made in India.

Other major pharmaceutical companies are working on a high and the achievable rate of effectiveness. They're probably going to be coming out soon.

Let us hope for good news in the future.

Great Indian opportunity to kick Chinese lost

  Recent Ladakh Truce Took Away a Great Indian Opportunity India gave away too much to buy peace in Ladakh. In fact, Chinese belligerence needed a big hard kick on their back but Alas! that opportunity is all gone. They attempted another piece of Salami slicing of Indian land and offered India that rare opportunity to kick them in the Himalayas. That opportunity would have laid to rest Chinese expansionist policies in the rest of Asia. India had all the advantages in all of Ladakh to capture back Akas-Chin plateau and severe the road link between Sinking and Tibet. In all probability Tibet would have been free and Pakistan would be at Indian mercy in spite of nuclear threat. Alas! it did not happen. Later we may regret that lost opportunity. This was the time to wash that 1962 blot of Chinese victory, a blot on Indian conscience. Question is that, why did they come and then why did they leave so quickly? Did they think that India is not well prepared and they can redo all that vict...

Start of the end of China’s Domination of the supply Chain

  Start of the end of China's domination of the supply chain. The spread of the COVID-19 pandemic with China at its centre, either intentionally or accidentally in 2020, has emerged as a boon to China's trade and economic dominance. Its rapid spread in most parts of the world has provided China a greater outlet for its products. When most of the world was closed to stop the spread of the virus, China was apparently open for business. Then the world started to recover. The vaccines did their part and extraordinary precautions were taken to allow the world to control the pandemic. By July or August of 2021, sufficient progress had been made for the world to recover. What was unknown at the time was the impact of pandemic on China itself. Their vaccines were 50% effective and guess work was that Chinese are as badly impacted by the virus as others. Yet they kept their factories humming for exports. There are two aspects of their exports 1). Merchandise exports. 2). Exports of supp...

We are back to Obama Administration

  We are back to Obama Administration with Joe Biden as president now. Most of his men are ex Obamaites. Does America have to recreate not so smart Administration of the bygone era. Yes, Obama smiled a lot which convinced the people that everything is OK. Not true......... China captured all the South China Sea, hence shipping and security of that region is in doubt. The Chinese overgrew in military might during Obama Administration and America kept importing stuff from China, filling up their pockets. That money went straight into their military and Obama and his men kept watching. Russia was threatened with war if they stepped one step further in Ukraine. As a matter of fact, neutralistic Eastern Europe closer to Russia is good for everybody. it is a buffer for advanced Western Europe, but Obama could not control his advisors not work to grab Ukraine into its own fold. Now there is an unending war with no results. And many more issues like that in Iraq and Pakistan. The latter co...
