A Peruvian volunteer died of new crown complications during a clinical trial of a Chinese medicine vaccine. Cayetano Heredia University, which is in charge of the trial, said on the 26th local time that the University conducted a double-blind trial. Some volunteers were vaccinated with placebo instead of vaccine, including the dead.
The University of Cayetano gave 12000 volunteers a vaccine or placebo. The school said that since the beginning of the trial, the death of volunteers has nothing to do with the vaccine. The school will report to the regulatory authorities and ethics agencies, maintain the phase III clinical trial, and issue a statement to express sympathy to the family members of the deceased.
Double blind trials are usually used when the subjects are human beings. The purpose is to avoid the subjective bias of the subjects or the experimenters to affect the results of the experiments. Generally, the results of such trials will be more rigorous.
Peru is one of the countries with the most serious epidemic situation in South America. So far, more than 1.1 million people have been infected and 40000 people have died. The number of medical institutions in many places of the country, including Lima, the capital, is close to saturation.
