FAIRLESS HILLS, Pa. (AP) — Drugmaker Pfizer on Tuesday reported a 32% plunge in second-quarter profit, as the global coronavirus pandemic limited marketing of new prescriptions for its medicines. Still, the biggest U.S. drugmaker posted a solid profit and nudged up parts of its 2020 financial forecast. Pfizer earned $3.43 billion, or 61 cents per share. Revenue fell 11% to $11.8 billion. Pfizer is among the drugmakers leading the race to develop a safe, effective vaccine against the coronavirus. Late Monday it announced the start of a late-stage trial of an experimental COVID-19 vaccine that it’s developing with German partner BioNTech.
