Which next-generation flu vaccines best boost immunity among older adults? A CT study seeks to find out.


The UConn Middle on Growing old is inviting adults 65 and older to enroll in a research centered on which flu vaccines are simpler amongst older folks.

Knowledge present that as much as 85% of mortality from the flu, and as much as 70% of hospitalizations, happens in folks age 65 and older. That’s on account of age-related weakening of the immune system response, so normal flu vaccines don’t work optimally.

The UConn Middle on Growing old will examine which age-related adjustments within the immune system scale back folks’s responses to the flu vaccine, and which next-generation flu vaccines greatest enhance immune responses.

In June, the Facilities for Illness Management and Prevention really useful particular flu vaccines for adults 65 and older, together with larger dose and adjuvanted flu vaccines.

“The aim is to provide them this yr, the Fluzone excessive dose vaccine, and the following yr give them the FluAD vaccine,” stated Dr. George Kuchel, director of the UConn Middle on Growing old on the College of Connecticut, in addition to chief of geriatric medication at UConn Well being.

The vaccines are FDA-approved and have been proven as being efficient in overcoming these declines in immune responses with getting older, Kuchel stated.

“This fashion, we’ll be capable of evaluate their immune responses,” he stated. “We all know from our earlier research, once we give an influenza vaccine to an older grownup, we discover that a few third of older adults develop superb antibody responses. And we all know one other third, don’t, with the opposite third being type of inbetween.”

The research is funded by a five-year, $9 million grant from the Nationwide Institute of Allergy and Infectious Illnesses to the UConn Middle on Growing old, the Jackson Laboratory, and Mount Sinai, to pinpoint age-related immune alterations that scale back influenza vaccine effectiveness.

Research contributors may have six visits for the 2022 and 2023 influenza seasons and 7 visits for the 2024 season on the UConn Middle on Growing old. There aren’t any prices to take part and financial compensation is offered for participation.

People 65 and older by Sept. 1, 2022, are eligible to enroll within the research, which is recruiting 60 contributors. Members should not have immunosuppressive problems or be on immunosuppressive medicines. To enroll, name 860-679-3043.
