US Democratic vice presidential candidate Kamala Harris says she would not trust President Donald Trump�s word about the efficacy of a possible coronavirus vaccine released prior to the November presidential election.

The California senator insisted during an interview with CNN - set to be aired on Sunday -- that she was not confident health officials would get the last word on the effectiveness of a vaccine.

I will say that I would not trust Donald Trump, and it would have to be a credible source of information that talks about the efficacy and the reliability of whatever he�s talking about.

CNN released excerpts of the interview on Saturday, in which Harris underlined that Trump had a track record of suppressing expert opinion about the COVID-19 outbreak and that she worried that might happen again in the case of a prospective vaccine.

If past is prologue that they will not. They�ll be muzzled, they�ll be suppressed, they will be sidelined because he�s looking at an election coming up in less than 60 days, and he�s grasping for whatever he can get to pretend that he�s been a leader on this issue when he�s not, she further emphasized. I will not take his word for it.

In a written statement, the White House insisted Harris� suggestion that politics is influencing vaccine approvals is not only false but is a danger to the American public.

Her remarks came amid rising concerns that the Trump administration is pressing towards the production of a vaccine before Election Day to boost his reelection chances.

CNN also reported Thursday that the US president has pressured officials to hasten the development of a vaccine to portray the sense that the end of the coronavirus pandemic is near.

This is while the Centers for Disease Control and Prevention (CDC) also asked state governors last week to fast-track applications for building permits for vaccine distribution sites that would be up and running in early November before Election Day.

Polling has shown voters remain doubtful of Trump�s word on a coronavirus vaccine, with only 14 percent in a Politico-Morning Consult survey in August, saying that they�d be more likely to receive a COVID-19 vaccination if the president recommended it.

By comparison, 46 percent said they�d take one on the advice of their family, while 43 percent said they would on the advice of the CDC or Anthony Fauci, the nation�s leading infectious disease expert.

Too much of the evidence points to the Trump administration pressuring the Food and Drug Administration to approve a vaccine by Election Day to boost the President�s re-election campaign, Senate Minority Leader Charles Schumer (D-NY) also said in a statement last week following a Washington Post report on the issue.

All Americans want a safe and effective vaccine as soon as possible, but if these important life and death decisions appear political, it will only undermine Americans� confidence in a vaccine and prolong the pandemic, he added.

More than 6.24 million Americans have so far been infected in the coronavirus outbreak, which has also taken over 188.500 lives, according to the latest tally by Johns Hopkins University Medical Center.
