• Why Does Smallpox Vaccine Shield Only Some? It’s in the Genes

How well people are protected by the smallpox vaccine depends on more than the quality of the vaccination. Mayo Clinic research shows individual genes can alter their response.

Senior author Gregory Poland, M.D., director of the Mayo Clinic Vaccine Research Group, says, “We were looking into the intercellular reactions that occur when vaccinated and unvaccinated persons are exposed to and infected with smallpox virus. We were able to use blood samples taken directly from vaccinated patients.We could see what would happen based on exposing a mixed-cell peripheral blood cell population to the vaccinia virus.”

The findings, gathered using sophisticated genomic screening, will appear in the online issue of the journal Genes & Immunity.
