China Conducts First Successful Test of Coronavirus Vaccine in Monkeys
PiCoVacc, an inactivated COVID 19 vaccine made by Beijing-based Sinovac Biotech, has reportedly shown promising results as the experimental vaccine could help protect rhesus macaques, a type of monkey native to India, from the virus. .
To perform the trial, the researchers injected the vaccine into the monkeys who were then exposed to SARS-CoV-2, which causes COVID 19 three weeks later. The report published in the scientific journal stated that the vaccine activated the immune response to produce antibodies against the new coronavirus. It was observed that these antibodies can also attack the normal virus.
The researchers also found that the monkeys who received a dose of PiCoVacc did not have the virus in their lungs after a week. While monkeys that did not receive the vaccine developed severe pneumonia.
Various reports say China has been testing vaccines in humans since mid-April. There is another vaccine made by the Chinese military institution, which is currently being tested in humans. In addition, meanwhile, Israel and Italy claimed to be successful in developing COVID 19 vaccines.
However, scientists may have a hard time recruiting for testing in the near future, as the number of COVID 19 patients remaining in China is only hundreds. A similar situation led to the development of the SARS vaccine in 2003.
