North Central Public Health District is asking the public to be patient as COVID-19 vaccine supplies remain limited.  The district says everyone who wants one will get one, but it will take time.  NCPHD officials say its vaccine allocation for this week is 300, and it is shared among Wasco, Sherman, and Gilliam counties.  They also noted the three counties have a 65 and older population of 7,250, and they are still vaccinating educators and child care providers.  North Central Public Health District is using an online booking system.  It’s a two-step process involving first signing up on the notification list for eligibility, then once their group is eligible people are emailed a link to the booking system to check for openings.  Mid-Columbia Senior Center is helping seniors with the booking process, call them at 541-296-4788.
