Inadvertent doses of Tdap given between the ages of 7 and 10 do not count as the 11-12 year old dose except as provided in subsection 4.6.4.5. A student who becomes pregnant may receive one dose of Tdap during the pregnancy (preferred during 27-36 weeks gestation) regardless of the number of years since a prior Tdap or Td vaccination.4.6. A student aged 7-10 years old who is not fully immunized with the childhood DTaP vaccine series must receive the Tdap vaccine as the first dose in the catch-up series and if additional doses are needed, the student should receive the Td vaccine. A child who receives the Tdap vaccine, is specifically excluded from the requirements of subsection 4.4.
