  1. To be completely correct, so called "delta variant" is the common name of at least 3 different viruses B.1.617.1, B.1.617.2, and B.1.617.3. But you will not see any separate statistics for B.1.617.1 or B.1.617.3 in most newspapers. Why? Because it does not worth efforts. That is why most news sources in the world did not show separate statistics for delta before June. They did show only general "COVID new cases". But since June it became clear to everyone that delta was much more dangerous and worth detecting. Therefore the date of detection (Thursday, 06/24/2021) more likely reflects the da
  2. Today we see that Chilie’s 7-days average COVID cases = 1328. This is 1328 x 328/19 = 22 925 cases/day if Chilie had the same population as the US. But the US has about 51k cases per day. So the vaccine that is used in Chilie is about twice more effective than the vaccine used in the US. That is why the effectiveness of the Chinese vaccines can be estimated as about 60-70 against delta.
  3. At the times of alpha variant Pfizer had 95+% efficiency and it was very very hard to get it outside the western countries. Now it is 39% efficient against delta (according to this - https://www.cnbc.com/2021/07/23/delta-variant-pfizer-covid-vaccine-39percent-effective-in-israel-prevents-severe-illness.html ) Therefore it has become very easy to buy Pfizer now (or even get for free). Maybe because most customers think that Sinovac is a better choice with about 50% efficiency.
  4. We see that efficiency of mRNA vaccines become lower with every new virus variant appeared every 3 months. It is about 64% for Pfizer (data from Israel) against delta COVID and I suppose that it is nearly the same for Moderna made with the same mRNA technology. 64% is very close to Sinovac and AstraZeneca efficiency levels. I expect that at the end of the year we will forget about delta variant of COVID and everybody will look for a medication for the deadliest omega variant. Moderna and Pfizer will be about 50% efficient against the omega variant (same as Sinovac and AZ) and it will be as e
  5. According to this study https://www.mdpi.com/2076-393X/9/7/779 Sputnik V is highly effective against Delta variant of COVID. And the producer of the vaccine always help customers to start local production as we see in Vietnam. That means the customers do not need to sale their sovereignty to get the vaccine.
  6. Thailand has enough vaccines for Phuket which is the main tourist destination.
  7. You seem to unaware of such a common thing as competitors. Coca-Cola will never approve Pepsi-Cola and you will not see AMD processors inside computers of Intel stuff. So Sputnik V will never appear in the US. This is a very natural thing called "competitors". And the US officials have said so many times that Russia and China are the competitors of the US that it is far time to suspect that it is true.
  8. I think it is far time to stop political BS and approve Sputnik V which is highly effective against delta variant: https://www.mdpi.com/2076-393X/9/7/779
