Study Details

Study Description

Brief Summary

The purpose of this observational study is to examine the risk of adverse events following vaccination with 10 or 13-valent pneumococcal conjugate vaccine (PCV10 or PCV13) among infants or children age <59 months and 23-valent pneumococcal polysaccharide vaccine (PPSV23) among adults age 65 years and older.

Condition or Disease Intervention/Treatment Phase
  • Biological: 10 or 13-valent pneumococcal conjugate vaccine
  • Biological: 23-valent pneumococcal polysaccharide vaccine
  • Biological: Influenza vaccine

Detailed Description

The purpose of this observational study is to examine 1) the risk of adverse events (AEs) following vaccination with 10 or 13-valent pneumococcal conjugate vaccine (PCV10 or PCV13) among infants or children age <59 months using a self-controlled risk interval design and 2) the risk of AEs following vaccination with 23-valent pneumococcal polysaccharide vaccine (PPSV23) among adults age 65 years and older compared with influenza vaccine recipients using a cohort design. We will use the national health insurance database from the National Health Insurance Service (NHIS) linked with the national immunization program registry data from the Korea Centers for Diseases Control & Prevention (KCDC).

Arms and Interventions

Arm Intervention/Treatment
PCV13 recipients (children)

Children < 5 years who had received PCV10 or PCV13 from May, 2014 to December, 2018 under the national childhood immunization program in South Korea.

Biological: 10 or 13-valent pneumococcal conjugate vaccine
a four-dose series that is indicated for use at 2, 4, 6, and 12 to 15 months of age.
Other Names:
  • Prevnar 13
  • Synflorix
  • PPSV23 recipients (elderly adults)

    Persons 65 years or older who had received at least one dose of PPSV23 between January, 2014 and December, 2018 under the national immunization program in South Korea.

    Biological: 23-valent pneumococcal polysaccharide vaccine
    Single 0.5-mL dose administered intramuscularly or subcutaneously only.
    Other Names:
  • Prodiax-23
  • Influenza vaccine recipients (elderly adults)

    Persons 65 years or older who had received at least one dose of influenza vaccine (as comparator) between January, 2014 and December, 2018 under the national immunization program in South Korea.

    Biological: Influenza vaccine
    One dose of trivalent influenza vaccine in flu seasons.

    Outcome Measures

    Primary Outcome Measures

    1. Relative risk of adverse events [2014-2018]

      the ratio of probability of adverse events occuring in the risk periods after vaccination with PCV10 or PCV13 versus the control periods in the self-controlled risk interval study design. the ratio of probability of adverse events occuring in the PPSV23 group versus the influenza vaccine (a comparator) group in the cohort study design.
