First COVID-19 Vaccine Test on Animals Showed Positive Results. PiCoVacc is The Name of This Vaccine.
On May 7, 2020, Chinese scientists published the first animal testing report on a COVID-19 vaccine candidate in the world.
PiCoVacc, a vaccine developed by Beijing-based Sinovac Biotech, is based on a well-known way of preventing the virus from infecting cells: Injecting a weak virus into an animal's body, causing the immune system to produce antibodies. Surprisingly, the antibodies can also destroy regular viruses.
They put the vaccine into rhesus macaques, a kind of monkey found in India, and then exposed the monkeys to SARS-CoV-2 after three weeks.
After another week, the monkeys that had gotten the greatest doses of the PiCoVacc had no virus in their lungs, showing that the vaccination was successful.
The monkeys that did not receive the vaccination, on the other hand, were infected with the virus and had severe pneumonia as a result.
Since mid-April, this vaccine has been subjected to human testing in China.
PiCoVacc might be humanity's new chance for avoiding the tragic and harmful impacts of SARS-CoV-2.
