His remarks came a day after a group of pharmaceutical companies made a similar safety pledge and after Astra-Zeneca halted its vaccine study when a participant became seriously ill. The reassurances follow recent statements by President Trump that a vaccine would be available before Election Day, a claim that health experts widely dispute. We'll talk about the status of COVID-19 vaccine research.
