SINOPHARM COVID-19 vaccine is very effective against mutant strains

Sri Lanka research shows that SINOPHARM COVID-19 vaccine is very effective against mutant strains such as Delta



SINOPHARM COVID-19 vaccine is very effective against mutant strains.   on July 20, Sri Jayawardenepura University, a well-known university in Sri Lanka, officially released its research report on the effectiveness of China’s Sinopharm inactivated vaccine.

According to the latest research results, the Sinopharm vaccine is very effective against the delta strain of the COVID-19 mutant strain. This is the first public report on the effectiveness of the Sinopharm vaccine against the current major epidemic mutant strains in the world.

The results of the study show that 95% of the population can produce antibodies after receiving two doses of the Sinopharm/BBIBP-CorV vaccine. Among them, the seroconversion rate of people aged 20 to 39 is as high as 98.9%, and the conversion rate of people over 60 years old is also 93.3%. The vaccine can induce the production of neutralizing antibodies in 81.25% of the population, and the level of neutralizing antibodies is similar to the level after the virus is naturally infected.

This study pointed out that the antibody levels of Sinopharm vaccine against delta strains and beta strains that are currently circulating are similar to those after natural infection, and the level of antibodies against alpha strains is relatively low. Compared with the epidemic strains in China, the antibody titers of the vaccinators to the Delta strain have only dropped by 1.38 times, which still has a better protective effect against the Delta strain. In addition, the research results show that the Chinese medicine vaccine can also induce T cell and memory B cell immune response.

According to the embassy, ​​Sri Jayawardenepura University is the only university in Sri Lanka with advanced technology and equipment for research on coronavirus. This research team includes famous Sri Lankan immunology experts Professor Neelika Malavige and Jiwanda Dr. Ra (Chandima Jeewandara) and researchers from the University of Oxford. Sri Lanka launched its COVID-19 vaccination program on January 29. According to figures released by the Ministry of Health of Sri Lanka, as of July 19, Sri Lanka had received 7.57 million doses of the COVID-19 vaccine and 5.93 million doses of Chinese medicine vaccines, more than 78% of the total. No serious adverse reaction related to the national medicine vaccine has been reported so far. .
