PORTLAND, Ore. (AP) — An Oregon hospital system has canceled vaccine clinics for Saturday and Sunday because of a major winter snowstorm expected to hit the Portland area. Oregon Health & Science University said Wednesday that it was closing its vaccine clinics for safety over forecasted snow and freezing temperatures. The National Weather Service says the city will likely get roughly 2 inches of snowfall from Thursday to Friday. OHSU says it is notifying patients, some at least 80 years old, and rescheduling appointments. Three sites will be closed, including Hillsboro Stadium.
