SALEM â No later than Monday, April 5, Oregon will give the green light to a large swath of residents to get their COVID-19 vaccinations. State officials donât know exactly how many people are becoming eligible for inoculation. But the group of newly eligible Oregonians comprises anyone who works a frontline job or is ages 16 to 44 with underlying conditions â including being overweight or having common health problems such as hypertension and asthma. By May 1, all healthy Oregonians 16 and older will get the official OK to get their shots. Thatâll amount to about 3.4 million people, or more than 80% of the population.
