Sri Lanka – Sri Lankan scientists reveal the truth about the effectiveness of the Chinese Sinopharm vaccine

Sri Lankan scientists revealed the truth about Chinese vaccines, which showed that their effectiveness did not exceed three months, despite China’s promotion of a recent study, claiming that the Sinopharm vaccine had an effectiveness of 95%, which shows China’s manipulation of data and facts in the study it published, intending to sell as much as possible of the vaccine, while the United States of America continues to donate the vaccine that has proven efficacy against all variants of Covid-19.
