Booster shots may be able to cut hospitalization rates in Europe by at least half a million patients, the European Union’s (EU) public health agency said on Thursday.
The ECDC figures cover the EU’s 27-nation bloc and the EEA—which consists of Iceland, Liechtenstein, and Norway. The EEA unites the three countries with the 27-nation bloc into a regional trade organization that follows the same rules, enabling merchandise and travelers to move freely about the EEA in an open and competitive environment.
According to the health agency, the uptake of primary COVID-19 vaccinations in the EU/EEA has been “increasing slowly” and reached 70 percent this week. Meanwhile, the uptake of booster shots has increased “more rapidly” and already 50 percent of adults in the EU/EEA have received a dose.
“Extending the booster program to all previously vaccinated individuals could reduce admissions by another 300,000 [to] 500,000,” the ECDC said.
Stella Kyriakides, EU’s Commissioner for Health and Food Safety, said authorities must remain vigilant in detecting potential future CCP virus variants, adding that although the peak of infections appears to have been reached recently, the pandemic is not over.
Effectiveness against hospitalization also dropped 9 percent among those who finished their primary regimen within six months of being admitted and nearly a quarter—down to 57 percent—among those who had gone over six months since the second dose of the initial regimen.
Moreover, the vaccines provided little protection against infection, researchers found.
“Although these findings provide evidence supporting that 3-dose schedules are protective and that booster doses are more protective than primary series alone, the significantly higher [odds ratio] for Omicron suggests that booster doses are less protective against Omicron than against Delta,” researchers said.
