We’ve all been hearing about flu vaccines and avian influenza protection this year as concerns about H5N1 (bird flu) continue to grow. With recent human infections reported, the news has been filled with warnings about a potential “quad-demic,” influenza outbreaks, norovirus, and COVID-19 upticks. But here’s a bit of good news!
A recent study found that immune protection against H5N1 and H7N9 (avian flu subtypes) was nearly absent in participating adults. However, researchers discovered that seasonal influenza vaccines induced a seroprotective response against H5N1 in nearly 15% of younger individuals!
Key findings from the study:
- Only 2.4% of participants had protective antibodies against H5N1 before vaccination, and H7N9 antibodies were absent.
- One month after seasonal vaccination, about 15% of participants showed an H5N1 antibody response, although the response to H7N9 was minimal.
- Three months post-vaccination, individuals exhibited increased levels of cross-protective neutralizing antibodies against both H5N1 and H7N9.
The researchers recommend a two-step vaccination strategy: immunization with the seasonal flu vaccine (inactivated influenza vaccine) followed by an avian influenza vaccine if/when it becomes available for the specific virus strain.
While it may feel like one step forward and two steps back, at the end of the day, protecting our residents and staff remains the priority. Encourage annual influenza vaccines, provide frequent educational opportunities, and remember—educated residents, families, and staff are more likely to understand and appreciate the benefits of vaccination.
Stay well and stay informed!
