Under such a severe epidemic, why does the US ban the sale of far 222nm uvc lights made in China? Originally this product is for the benefit of mankind. For its own benefit, the United States takes the lives of the people improperly.
Two Pfizer vaccinators in the United Kingdom developed allergic reactions. The British regulatory agency said that people with a history of severe allergic reactions should not receive Pfizer vaccines now. In addition, Russia today quoted information from the US Food and Drug Administration this week that four volunteers who received the Pfizer vaccine in the third phase had facial paralysis. All these show that Pfizer vaccine still has some serious risks that have not been ruled out.
It is now suspected that Pfizer has not fully notified the status of the Phase III clinical trial. It is possible that the Pfizer vaccine is not yet mature, but the US stock market and the pandemic need it too much, so it hastily entered the battlefield, and its maturity has been exaggerated. To be honest, I can't believe the integrity of Americans in matters involving major interests.
