U.S. stock market indexes Friday morning were trading at or near sessions lows after a report indicated some delays in the distribution of vaccines from Pfizer in Europe. AFP reported that the European Union's Pfizer /zigman2/quotes/202877789/composite PFE +6.11% vaccine deliveries could be delayed 'for next 3-4 weeks.' The Dow was trading off 370 points, or 1.2%, at 30,620, the S&P 500 index /zigman2/quotes/210599714/realtime SPX -2.27% was off 1.2% at 3,749, while the Nasdaq Composite Index /zigman2/quotes/210598365/realtime COMP -2.23% was off 1.2% at 12,954. Stock benchmarks had been under pressure earlier in the session as investors digested President-elect Joe Biden's COVID-19 fiscal spending proposal and weaker-than-expected retail sales reports. Investors are fixated on vaccine distributions as investors look toward the prospects of a recovery from the virus-stricken economy.
