Summary:

      The purpose of this pilot research project is to look at the effect of the inactivated
      influenza vaccine (seasonal flu shot) on early signs of immune or germ-fighting response
      known as cytokines or signal molecules. The investigators also want to see if the timing of
      vaccine administration has any effect on women's reproductive hormones. The investigators
      hypothesis is that influenza vaccine given right before ovulation may change the hormone
      levels usually seen after ovulation. Thi
