As fears of a second wave of the coronavirus increase, experts and scientists across the world have been under pressure to develop a more effective vaccine.
World governments have invested millions in researches to find the right vaccine to fight the pandemic. In countries like the UK and the US trials of different approved vaccines have been conducted.
The president of the US, Donald Trump, had been pressurising the Food and Drug Administration (FDA) to authorise the use of a Covid-19 vaccine before the conclusion of the normal clinical trial process as the number of cases in the US rose to 6 million on Sunday.
Stephen Hahn, the FDA commissioner supported Trump`s idea saying, he was ready to give an emergency approval of the Covid-19 vaccine before the end of Phase 3 of human trials which test the drug for safety and efficacy.
However, public health experts have raised concern over the issuing of the vaccine before stringent safety testing.
Dr Angela Rasmussen, a virologist at New York’s Columbia University, said: “We absolutely cannot tolerate or accept an emergency authorization for any Covid-19 vaccine without reliable safety and efficacy data from phase three clinical trials”.
Donald Trump wants the FDA to approve the use of the Covid-19 vaccine before the November election.
Hahn said the authorization of the vaccine before the normal clinical process was necessary as “the benefit outweighs the risk in a public health emergency”. “This is going to be a science, medicine, data decision. This is not going to be a political decision,” he said.
Earlier this month, Russia had been criticised for approving and administering a vaccine before phase three trials.
