Tens of thousands of Covid-19 booster doses are arriving in Oregon this week as state health officials, pharmacies and providers plan vaccine clinics and schedule shots.
The federal Centers for Disease Control and Prevention approved the new booster doses by Moderna and Pfizer-BioNTech on Thursday and a West Coast scientific group representing Oregon, Washington, California and Nevada followed with its own endorsement, paving the way for vaccinations to begin.
Both boosters are designed to fight the original strain of the virus along with the two latest and most infectious omicron variants, BA.4 and BA.5. This is the first time that a vaccine has targeted those strains, which have caused the majority of recent infections in Oregon and across the country.
“The original two doses of vaccine offer less protection against these omicron variants that are the predominant strains in Oregon and the United States,” Dr. Dean Sidelinger, state epidemiologist, told the Oregon Capital Chronicle. “They were very good against the original strain, but are proving less effective at protecting against the omicron strain, as people are further out from their last dose.”
He said the new boosters are safe and effective and the best way for Oregonians to protect themselves from a severe Covid infection, hospitalization or death.
“OHA encourages all Oregonians who are eligible for boosters to get one,” Sidelinger said.
The Pfizer shot is approved for ages 12 and older, and the Moderna booster is for people who are at least 18. Either shot can be given, regardless of which vaccine the person had before, but it should be administered at least two months after the last booster, a Johnson & Johnson vaccine or the second dose of the Pfizer or Moderna vaccine.
Studies have shown that over time, immunity against Covid-19 subsides.
“We know that immunity, from watching the cases that come in, does tend to wane after two or three months of getting a dose of the original vaccine,” Sidelinger said. He said the CDC has changed its definition of what it means to be fully vaccinated: Those who have had the primary series and the first booster dose are considered up to date on their Covid vaccines. Oregon Health Authority data shows that fewer than 50% of adults in Oregon – 1.6 million people – are fully vaccinated based on the CDC’s latest definition.
Older people are more likely to be vaccinated in Oregon. State data shows that 69% of those 65 and older are fully vaccinated. That compares with 52% of those 50 through 64 year old and 37% of those aged 20 through 49. Nearly 28% of teenagers (12 to 17) have all their Covid-19 doses; only 8% of younger children do.
Two groups – people with weakened immune systems and the elderly – face a higher risk of severe illness and death. Covid remains the third leading cause of death in the U.S.
Since the pandemic struck in early 2020, the virus has sickened about 880,000 people in Oregon and killed more than 8,400. It has packed emergency rooms and caused hospitals to run out of beds. But new infections have slowed. This week the state has a seven-day average of about 600 cases a day, according to Oregon Health Authority data. The average number of new daily infections was about double that in July. Illnesses peaked on July 13, with about 5.5% of Oregon residents infected, according to the latest forecast by Peter Graven at Oregon Health & Science University.
But that doesn’t mean the virus has gone away. Nearly 270 people are currently hospitalized with Covid-19, including 35 in intensive care units, health authority data shows.
