High-Dose Flu Shot 30% More Effective at Reducing Senior Hospitalizations
It has been recognized for many years that people 65 years and older are at greater risk of serious complications from the flu because human immune defenses become weaker with age.
Seniors with weaker immune systems often have a lower protective immune response after flu vaccination compared to younger, healthier people, says the Centers for Disease Control and Prevention (CDC).
This can make seniors more susceptible to the influenza virus.
But, which flu vaccine, high-dose or standard-dose, is best for seniors?
A new study says that the high-dose influenza vaccine was 30.7 percent more effective in preventing flu-related, senior hospitalizations.
To compare 2 types of senior-recommended flu vaccines, these researchers from the Oregon Public Health Division assessed senior high-dose (HD) vaccine effectiveness (VE) against influenza-related hospitalization by linking immunization registry records to hospitalization data sets.
