Seasonal Flu Vaccine Study

The Twin Research Registry at SRI International is recruiting twins for a seasonal flu vaccine study led by Stanford University. Twins will be provided – free of cost –the same flu vaccine that is given to the general public. Healthy fraternal and identical twins in the following age groups are currently needed to participate:

  • Identical twins aged 2-5 years old
  • Fraternal twins aged 12-49 years old

The study is sponsored by the National Institutes of Health, with a goal to ultimately help scientists develop more effective vaccines. This is the eighth year that twins have been included in Stanford University’s vaccine studies.

Compensation will be provided for time and travel expenses, and zygosity will be determined.

For the study described above, both twins in a pair need to participate.
