People 65 and older, as well as most people with compromised immunity, are now authorized to receive a second bivalent COVID-19 booster dose.  The second bivalent dose was available in Oregon on Monday.  The updated booster doses are available at local doctor’s offices and pharmacies.  They are also offered by North Central Public Health District.  To make an appointment, call 541-506-2600.  Those 65 and older can get a second bivalent booster if it’s been at least four months since their first bivalent booster.  People who are immunocompromised can receive a second bivalent booster at least two months after their last updated booster.  They can receive further boosters on a schedule determined by their doctor.  The bivalent mRNA vaccines from Pfizer and Moderna were initially authorized last September as single-dose boosters, and federal health authorities last week authorized and recommended a second bivalent booster dose for certain at-risk populations.
