Dr. Francis Collins, the director of the National Institutes of Health, took issue on Wednesday with President Trump’s suggestion that a coronavirus vaccine would be available by Election Day, as he repeatedly sought to reassure senators and the public that a vaccine would not be made available to the public unless it was safe and effective. “Certainly, to try to predict whether it happens on a particular week before or after a particular date in early November is well beyond anything that any scientist right now could tell you and be confident they know what they are saying,” Dr. Collins told a Senate panel at a hearing on the effort to find a vaccine. Wednesday’s hearing, before the Senate Health, Education, Labor and Pensions Committee, came amid growing concern over whether people would be reluctant to take a coronavirus vaccine, and whether Mr. Trump would apply political pressure on his administration to quickly approve one to give him a lift in his re-election bid against former Vice President Joseph R. Biden Jr.On Tuesday, a group of drug companies all in the race to develop vaccines pledged that they would not release any vaccines that did not follow rigorous efficacy and safety standards. Hours later, a leading vaccine developer, AstraZeneca, announced that it had suspended a large-scale clinical trial of a vaccine candidate after a patient experienced what may be a severe adverse reaction. Dr. Collins pointed to that development as “a concrete example of how even a single case of unexpected illness is sufficient to hold a clinical trial in multiple countries” — and evidence that “we cannot compromise” on safety.
