(Portland, OR)  --  Health officials say fewer than three-thousand first time vaccinations were added in Oregon Wednesday, and the upcoming heat wave could cause even fewer people to go to vaccination clinics over the weekend.  The Oregon Health Authority says 35-thousand-290 vaccinations are still needed to reach 70-percent vaccination, which is when most of the restrictions in Oregon will be dropped.  The vaccination rate is currently at 68-point-nine-percent.  Governor Kate Brown plans a news conference today to address the reopening.
