The Journal of the prestigious American Medical Association published a reviewed study that concluded that Chinese Cinofarm's anti - corona vaccine is effective.

The study said that the clinical trials conducted included 40,000 volunteers in Bahrain, Egypt, Jordan and the Emirates.

None of the volunteers in these clinical trials had any severe ill health.

Only on a very rare scale have any side effects of the vaccine recipients, most of which have nothing to do with the vaccine.

The two vaccines adopt the traditional way of responding to the epidemic, namely, the crippling virus being addressed.

The study found that the vaccine was effective from 72.8% to 78.1% in cases of corona with symptoms.

The two vaccines also showed effectiveness of up to 100 percent against severe cases of HIV-induced Covid-19.

Vaccines led to the production of measurable antibodies among participants in clinical trials.

This interim analysis is statistically useful for vaccine effectiveness, according to the study.
