(Portland, OR)  --  The FDA has approved using the Pfizer vaccine on children between the ages of 12 and 15 to prevent COVID-19, but it'll be a few days before kids can get the shot here in Oregon.  The Western States Scientific Safety Review Workgroup needs to give its approval first.  That's been the same process for all of the vaccines that have been released so far.  After that approval is given, the Oregon Health Authority will allow the shots to be administered to the younger kids.
