PORTLAND, Ore. (KOIN) — The Food and Drug Administration and Centers for Disease Control and Prevention ruled Thursday that 16- and 17-year-olds can get a third dose of Pfizer COVID-19 vaccine.

Shortly after the authorization, the Western States Scientific Safety Review Workgroup, including Oregon, Washington, California and Nevada, released a statement supporting the CDC’s recommendation.

Then the Oregon Health Authority updated guidance for providers so those 16- and 17-year-olds who finished their Pfizer vaccination series at least 6 months earlier can now get a booster.

State epidemiologist Dr. Dean Sidelinger said, “The scientists, medical experts and health officials who reviewed studies on the effectiveness of COVID-19 vaccines have determined that the benefits provided by a booster merit their use for this group.”

Virus experts say the booster is worth getting.

However, high demand for the jab means it may take a bit of work to find an appointment.

Many adults are trying to get booster shots right now, and parents are still trying to get kids ages 5 to 11 their first shot, which was just approved for them last month.

Walk in clinics may be parents’ best bet if they are looking to have their 16- or 17-year-old vaccinated with a booster.
