In a study from the University of North Florida and elsewhere, scientists found dual COVID-19 and seasonal influenza vaccinations are linked to reduced infection risks.
It can be an effective strategy to reduce the contagious respiratory disease burden during the winter.
In the study, the team used data from the 2021 National Health Interview Survey to examine the association between dual vaccination status and self-reported COVID-19 infection and severity.
Among those in the survey, about 22% did not receive either the flu or COVID-19 vaccine, 6.0% received the flu vaccine only, 29.1% received the COVID-19 vaccine only, and 42.5% received both vaccines.
They found people with dual vaccination and COVID-19 vaccine only were much less likely to report COVID-19 infection when compared with those unvaccinated.
There was no big difference in self-reported COVID-19 symptom severity by vaccination status.
If you care about COVID, please read studies about the cause of long COVID ‘brain fog’, and many people older than 50 get shingles after COVID-19 infection.
For more information about health, please see recent studies about plant nutrients that could help reduce high blood pressure, and these antioxidants could help reduce dementia risk.
The study was conducted by Dr. Zhigang Xie et al and published in the journal Vaccine.
