Dosage and Administration

Women and Girls 9 to 26 yr of age

  • Use the full recommended dose of the vaccine; no dilution or reconstitution is necessary.
  • Do not dilute or mix with other vaccines.
  • Shake well immediately before using, which will yield a white, cloudy liquid.
  • Prior to administration, inspect visually for particulate matter and discoloration. Do not use if product has particulates or appears discolored.
