North Central Public Health District is asking anyone who attempted to sign up for COVID-19 vaccine notifications at its website at ncphd.org between 2 p.m. and 6 p.m. this past Thursday to do so again.  The district says due to a technical difficulty, forms submitted in that time period were not received in the database.  Those who sign up through the site will be notified once their group is eligible to get the vaccine, and they will be sent a link to sign-up for an appointment.  The district does emphasize vaccine supplies are still limited and slots fill up quickly.  People are encouraged to check at ncphd.org regularly to find available appointments as new vaccine clinics are added to the schedule.  NCPHD says through January 29, there were 3,426 vaccines administered in Wasco, Sherman, and Gilliam counties.
