The vaccine was supposed to stimulate immune reactions in all volunteers, who received it during the first phase of the test.
The primary results showed that the vaccine is effective. However, it may cause a number of side effects, such as fatigue, shivers, headache, and pain in muscles and in the place of injection.
During phase one, the drug was distributed among the selected number of healthy people. Currently, the tests enter phase two, and the extended clinical probes are commencing. This includes patients from different age groups who experience health problems.
Phase three foresees the involvement of thousands of volunteers, which will let the researchers be more specific about the efficiency and safety of the new drug. When it is complete, scientists will decide whether the massive release of the vaccine should take place.
Previously, the media reported that 17 vaccines are being tested worldwide.
