The world is now being drafted at least 70 of vaccines against coronavirus, said the world health organization.
In published April 11, the list of companies involved in developing vaccines, said that 67 drugs undergo a stage of pre-clinical studies, three have already started to test on humans.
Clinical trials already carried out by the Chinese company CanSino Biologics in conjunction with the Beijing Institute of biotechnology, as well as the American company Inovio Pharmaceuticals and Moderna.
More than any other in the trials progressed CanSino Biologics, which is already in the second stage of clinical trials. Last week, the company announced the recruitment of 500 volunteers for further testing of the vaccine, reported the South China Morning Post.
In the first phase the vaccine was introduced in 108 volunteers from Wuhan, where there was an outbreak of the disease. They were divided into three groups who received low, medium and high dose vaccine. In the first stage, as noted by the researchers, there were some side effects in patients who were administered a high dose of the drug: they had a fever to 38.5 degrees. Fever is usually passed within 24 hours, but in the second stage, the researchers plan to use low and medium doses.
Clinical trials consist of three stages, the latest study involved more people than the first two.
The Agency Bloomberg notes that usually from the beginning of the development of a vaccine on the market is 10-15 years, but in the case of coronavirus pharmaceutical companies are seeking to reduce this time and produce the vaccine by next year.
In vaccine development are also involved pharmaceutical giants such as Pfizer, American and French Sanofi, but they are still in the earlier stages of testing.
Flash COVID-19 began in December 2019 in China. March 11, 2020, the world health organization declared the spread of the coronavirus pandemic.
