C. Rotavirus vaccine (RV)
                                             1. Rotavirus is a cause of serious gastroenteritis and is a
                                                nosocomial (hospital-acquired) pathogen that is most
                                                severe in children 3 to 24 months of age; children
                                                younger than 3 months have some protection because
                                                of maternally acquired antibodies.
                                             2. Vaccines are available and are administered by the
                                                oral route because the vaccine must replicate in the
                                                infant’s gut.
                                             3. Vaccine may be withheld if an infant is experiencing
                                                severe vomiting and diarrhea; it is administered as
                                                soon as the infant recovers.
                                D. Diphtheria, tetanus, acellular pertussis (DTaP); tetanus toxoid;
                                   reduced diphtheria toxoid and acellular pertussis vaccine (Tdap
                                   adolescent preparation)
                                             1. Administered by intramuscular route
                                             2. The Tdap (adolescent preparation) is recommended at
                                                11 to 12 years of age for children who have completed
                                                the recommended childhood DTaP series but have
                                                not received a tetanus and diphtheria toxoid (Td)
                                                booster dose; children 13 to 18 years old who have not
                                                received Tdap should receive a dose.
                                             3. Td does not provide protection against pertussis; Td is
                                                used as a booster every 10 years after Tdap is
                                                administered at 11 to 18 years of age.
                                             4. Encephalopathy is a complication.
                                             5. Contraindications: Encephalopathy within 7 days of a
                                                previous dose or a severe allergic reaction to a
                                                previous dose or to a vaccine component
                                E. Haemophilus influenzae type b (Hib) conjugate vaccine (Hib)
                                             1. Protects against numerous serious infections caused
                                                by H. influenzae type b, such as bacterial meningitis,
                                                epiglottitis, bacterial pneumonia, septic arthritis, and
                                                sepsis
                                             2. Administered by the intramuscular route
                                             3. Contraindications: Severe allergic reaction to a
                                                previous dose or vaccine component
                                F. Influenza vaccine: Vaccine is recommended annually for children
                                   beginning at age 6 months.
                                G. Inactivated poliovirus vaccine (IPV)
                                             1. IPV is administered by the subcutaneous route (it may
                                                also be given by the intramuscular route).
                                             2. Contraindications: Severe allergic reaction to a
                                                previous dose or vaccine component; components
                                                may include formalin, neomycin, streptomycin, or
                                                polymyxin B
                                H. Measles, mumps, rubella (MMR) vaccine
