Take the human trial of coronavirus vaccine for example, this trial tests the vaccine on 45 males and non-pregnant females between the ages of 18 and 55. Its participants aren’t actually receiving the virus through the injection, they’re not at risk for contracting COVID-19 through the testing program.
According to a US government official, first human trial of coronavirus vaccine began on Monday 16 Mar 2020. The first human participant received an experimental dose to test for potential side effects.
Public health officials say it will take a year to 18 months to fully validate any potential vaccine. Testing will begin with 45 young, healthy volunteers with different doses of shots co-developed by NIH and Moderna Inc.
