The Vaccine for Corona Virus has been directly tested on human begins. earlier they used to test the efficacy of medicines on rats and animals. Now for the first time, the vaccine is directly used on human beings.
Coronavirus vaccine, researchers aren’t waiting to see how well it prevents infection in animals before trying it in people, breaking from the usual protocol.
“I don’t think proving this in an animal model is on the critical path to getting this to a clinical trial,” said Tal Zaks, chief medical officer at Moderna, a Cambridge, Mass.-based biotech that has produced a Covid-19 vaccine candidate at record speed.
He told that scientists at the National Institutes of Health is “working on nonclinical research in parallel.” Meanwhile, the clinical trial started recruiting healthy participants in the first week of March.
That isn’t how vaccine testing normally happens. Regulators require that a manufacturer show a product is safe before it goes into people, and while it isn’t enshrined in law, researchers almost always check that a new concoction is effective in lab animals before putting human volunteers at potential risk.
