A Prospective, Randomized, Open-label Clinical Trial to Assess Fever Following Simultaneous Versus Sequential Administration of PCV13, DTaP Vaccine and IIV in Young Children

A prospective, randomized open-label clinical trial that will be conducted during the
2017-2018 influenza season. During the 2017-2018 season, approximately 280 children will be
enrolled at Duke University Medical Center and Kaiser Permanente Northern California.
Eligible children will be randomized to receive simultaneous or sequentially administered US
licensed PCV13, US-licensed DTaP vaccine, and US-licensed inactivated influenza vaccine
(IIV). Children in the simultaneous group will receive PCV13, DTaP, and IIV vaccines at Visit
1, and then return for a health education visit without vaccination about 2 weeks later
(Visit 2). Children in the sequential group will receive both PCV13 and DTaP without IIV at
Visit 1, and then will receive IIV and health education about 2 weeks later (Visit 2).
Parents will record the occurrence of fever, solicited adverse events, medical care
utilization, and receipt of antipyretics over 8 days following Visit 1 and Visit 2. In
addition, febrile seizures and serious adverse events will be recorded for the entire study
period (from enrollment through 8 days following the Visit 2) as determined through parental
report and chart review. Parental perceptions about their child's vaccine schedule will be
assessed on the 8th day following Visit 2.

Inclusion Criteria:

1. 12 through 16 months of age (i.e. from the 1-year birthday until the day before 17
months of age) at the time of vaccination

2. Stable health as determined by investigator's clinical examination and assessment of

receive DTaP and PCV13 in addition to this season's IIV

5. The parent(s)/LAR(s) must be willing and capable of providing permission for their

8. The parent(s)/LAR(s) must agree to sign a medical release for the child so that study

pneumococcal vaccine.

8. History of a severe allergic reaction (e.g., anaphylaxis) to any component (including
egg protein) of any of the three vaccines used in this study; or a latex allergy.

9. History of Guillain-Barré syndrome within 6 weeks following a prior dose of influenza,
DTaP, or tetanus toxoid containing vaccine

12. History of collapse within 3 days after a prior dose of DTaP

13. Received any other licensed vaccines within 14 days (for inactivated vaccines) or 28
days (for live vaccines) prior to Visit 1

14. Received an experimental/investigational agent (vaccine, drug, biologic, device, blood
product, or medication) within 28 days prior to Visit 1, or expects to receive an
experimental/investigational agent during the study period (up to 8 days after visit
2)

15. A moderate to severe acute illness within 72 hours of Visit 1

16. A reported temperature greater than or equal to 100.4°F (38.0°C) within 72 hours prior
enrollment or a temperature (measured by temporal artery thermometer) greater than or
equal to 100.4°F (38.0°C) at the time of enrollment

17. Receipt of an antipyretic medication (acetaminophen or ibuprofen) within 24 hours
prior to enrollment

18. Parent(s)/LAR is planning to administer a prophylactic antipyretic or medication on
