LOS ANGELES, Jan 15 (Reuters) - The incoming administration of Democratic President-elect Joe Biden will seek to vaccinate all people over 65 and frontline workers, as Biden seeks to administer 100 million COVID-19 vaccines during his first 100 days in office. The Biden team said that after he takes office on Jan. 20, Biden will use the Defense Production Act to increase supply of vaccine vials, syringes, needles and related equipment to try and speed up the vaccination of Americans.
