Chinese scientists tested the effect of inactivated vaccine against coronavirus in mice, rats and monkeys, reports TASS. As follows from the results of the studies placed in electronic library bioRxiv, the animals began to develop antibodies that can neutralize different strains of SARS-CoV-2.
Note, the article has not yet been reviewed by independent experts and editors of scientific journals. Therefore, the researchers ‘ conclusions should be treated with caution.
“We have organized a pilot production of purified inactivated vaccine PiCoVacc that made mice, rats and primates produce antibodies that can neutralize at least ten different strains of the virus SARS-CoV-2. Small and large doses of this vaccine are partially or completely protected macaques from infection COVID-19,” write the authors.
The specialists of the Chinese pharmaceutical company Sinovac and the Chinese Academy of Sciences tested the effect of vaccine based on inactivated viral particles.
As the creators of the vaccine, it is possible to move to clinical trials PiCoVacc on volunteers, which will begin in the near future.
In recent months, scientists from many countries of the world announced the beginning of tests of various types of vaccines against coronavirus, a new type. Some of them developers check in experiments on animals and others on humans. The first results of the tests, scientists expect, will be known only after about a year and a half, if the methods of testing vaccines will not change.
Many of these drugs are based on untested technology, which allows you to enter in human cells, the RNA fragments and cause them to produce large quantities of virus proteins.
Being developed and classical inactivated and recombinant vaccines based on attenuated virus particles, and the finished shell fragments of the virus. In fact, and in another case, the creation and mass production of such drugs will be very difficult, and guarantee their success yet.
