A clinical trial for a coronavirus vaccine has been completed on volunteers in Russia with success, reported the Sechenov First Moscow State Medical University.
The trials started in June and were carried out on 38 volunteers divided in two groups. The vaccine consisted in an intramuscular injection. Some of the initial side effects, including high body temperature and headaches, were no longer noticeable after 24 hours of administration.
Some of the conditions for the trial specify that the participants need to remain isolated for four weeks to avoid other infections. They will be monitored for half a year thereafter.
The vaccine is also being tested in liquid form at Burdenko Military Hospital in Moscow. The first group of volunteers is scheduled to finish on July 15th.
The sample size of volunteers was rather small and researchers have pointed out that more that more testing would be needed before the vaccine could be approved for effective use and protection against Covid-19.
