however, the vaccine can be obtained within 11 months, that is, the beginning of the third quarter of 2020. “Preclinical studies will take up to 6 months, the first phase of clinical trials will take up to 5 months. Thus, in 11 months we will be able to ready a vaccine”, – quotes words of the head of the FMBA of Russia Veronika Skvortsova, the press service of the Agency.
SC established a working group on the prevention of the spread of coronavirus
Earlier it was reported that SRC VB “Vector” of Rospotrebnadzor has developed a prototype vaccine against a coronavirus. They have already begun to test in vivo in sensitive laboratory animals. Traditionally these studies use laboratory mice and rats, ferrets are also used, lower primates and other animals. This is just the pre-clinical stage.
the Stage is required because you need to ensure safety and effectiveness of a new drug, and studies on cell cultures, unfortunately, cannot give answers to all the questions, because living organisms is much more complex than cell culture. In addition, many of the effects in cellular studies to simulate difficult – in particular, how to respond to the immunity to the new vaccine. It is also necessary to determine the most effective dose and frequency of administration of vaccines, method and scheme of vaccination. Therefore, without using laboratory animals, scientists can not do.
Only after successful completion of animal trials can begin clinical trials on volunteers.
