　　China News Agency, Beijing, July 20th. Colombo: Sri Jayawardenepura University released a research result on the 19th, stating that 95% of the population in the country who received two doses of the Chinese new crown vaccine All personnel have developed antibodies.

Moreover, this vaccine is "very effective" against the delta mutant strain.

　　The study showed that 95% of the population can produce antibodies after being vaccinated with two doses of Sinopharm/BBIBP-CorV vaccine.

In 81.25% of the population, the vaccine can induce the production of neutralizing antibodies, 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 the currently circulating delta variant strain and beta strain are similar to those after natural infection, and the level of antibodies against the alpha strain is relatively low.

Compared with the epidemic strains in China, the antibody titers of the vaccinators against the Delta strain have only dropped by 1.38 times, and they still have a better protective effect against the Delta strain.

In addition, the research results show that the Chinese medicine vaccine can also induce immune responses of T cells and memory B cells.

　　Sri Jayawardenepura University is the only university in Sri Lanka with advanced technology and equipment for research on coronavirus.

The team responsible for the above-mentioned research includes famous Sri Lankan immunology experts Professor Malawige and Dr. Jiwandala, as well as related researchers from the University of Oxford.
