• Three polio (IPV)
• One measles, mumps, and rubella (MMR)
• Two H influenza type B (HiB)
• Three hepatitis B (HepB)
• One chicken pox (VZV)
• Four pneumococcal conjugate (PCV)
• One hepatitis A (HepA)
• Two or three rotavirus (RV) (the number of doses depends on which vaccine is given)
• Two influenza (flu)

Who was measured?
PrimeWest Health members who turned 2 years old during the measurement year who were continuously enrolled for 12 months prior to their 2^nd birthday and had no more than one 45-day gap in enrollment during this time were measured.
