July 20 (Reuters) - Futures tracking the S&P 500 and Dow indexes pared early declines to trade marginally higher, as hopes of a coronavirus vaccine offset concerns about the economic damage from a surge in domestic COVID-19 infections.
German biotech firm BioNTech and U.S. drugmaker Pfizer reported additional data from their experimental coronavirus vaccine that showed the vaccine was safe and induced an immune response in patients.
At 9:01 a.m. ET, Dow e-minis were up 15 points, or 0.06%, and S&P 500 e-minis were up 1.25 points, or 0.04%. Nasdaq 100 e-minis, which were up before the report, hit session highs. (Reporting by Sagarika Jaisinghani in Bengaluru; Editing by Shounak Dasgupta)
