Nearly 73% of adults in Oregon are vaccinated, but the delta variant "has changed everything," Brown said on Twitter.
"I know Oregonians are tired of wearing masks. I certainly am too. But every time someone wears a mask that’s one more unvaccinated kid we’re protecting. That mask could keep your best friend or loved one out of the hospital," she tweeted.

WHO announces trial to test 3 candidate drugs as potential COVID treatments
WHO Director General Dr. Tedros Adhanom Ghebreyesus on Wednesday announced Solidarity PLUS, a new trial involving thousands of researchers in 52 countries to test three drugs as potential COVID treatments: artesunate, a treatment for severe malaria; imatinib, a drug for certain cancers; and infliximab, a treatment for immune system disorders such as Crohn’s disease.
In October, the WHO reported results of the Solidarity Trial, which tested four drugs as potential COVID-19 treatments: remdesevir, hydroxychloroquine, lopinavir and interferon. The trial, which involved nearly 13,000 patients in 30 countries, showed all four drugs had little or no effect on hospitalized patients with COVID-19. Final results from the Solidarity Trial are expected next month.
