I also think that Pfizer and Sputnik is the safest and best to use for covid vaccination. I really don't have trust for all covid vaccines from China. Also our country already experienced the bad effect of the Dengvaxia vaccine from China before but it was not for Covid but also killed a lot of children's lives. Scary to take and vaccinate covid vaccine from China.
Pfizer has refused to provide vaccines to third world countries. They have reserved 99% of their vaccines to developed nations such as the United States and Canada. Pfizer has provided limited doses of the vaccine to some of the third world nations, but in return they are asking for draconian guarantees. And as far as Sputnik V is concerned, they are really struggling to cope up with the demand. The good news is that their facilities in Argentina and Serbia has started producing the vaccines and by next month tens of millions of doses will be available for export.
The bad news about Sputink-V is that they are engaged in systemic data forgery. Brazil refused to use it, the reason - the national pharmaceutical regulator declares serious deviations from the declared standards in the trial batch of the vaccine. Slovakia also - the pharmaceutical regulator of Slovakia said that the drug that the country received differs from the one for which the data were provided (and even then not in full). Registration of the drug is faced with a problem everywhere - Russia does not provide all the necessary data or falsifies them ... Well, the "cherry on the cake" - statistics from Russia, which was published without thinking much: in comparison with January-February 2020 to January-February 2021 mortality in Russia grew by 30% (it is still easy to find on the official websites). At the same time, they officially claim that there is no increase in mortality from Covid and seasonal diseases, there is no answer to the question of the reasons. But the answer is most likely that in December 2020, active vaccination of residents of Russia began, thereby Sputnik-V. Then draw your own conclusions ...
And from the point of view of logic - what do you think - if people constantly manipulate data, lie, falsify data, try to slip something incomprehensible instead of the promised drug, systematically do not provide detailed research data - does this cause any suspicion in you? Would you do business with such people?
