PORTLAND â Officials from the Oregon Health Authority released updated mask guidelines Tuesday, May 18, saying that businesses and churches can choose to no longer require masks and distancing for fully vaccinated people, but those places must have visitors show proof of vaccination. In addition, mask requirements are no longer applied to anyone who is outdoors, although health officials recommend that people continue to wear a mask in crowded areas and in large gatherings. "(Last) week's announcement from the CDC emphasizes the point that safe and effective vaccines are the very best way to protect people from getting and spreading COVID," said Patrick Allen, the director of the health authority. "That's why it's safer for life to look more like normal for people who are fully vaccinated. And why people who haven't had a chance to get vaccinated should do so as soon as they can."
