Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 1 year (Child)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Occurrence of reported cases of hospitalisations and deaths due to pertussis in infants ≤6 weeks of age, in post-vaccination period compared to pre-vaccination period of Boostrix vaccination
Time Frame: During the 9-year period (January 2005- December 2014)
During the 9-year period (January 2005- December 2014)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Occurrence of reported cases of hospitalisations and deaths due to pertussis in infants 7 weeks to ≤12 months of age, in post-vaccination period compared to pre-vaccination period of Boostrix vaccination
Time Frame: During the 9-year period (January 2005- December 2014)
During the 9-year period (January 2005- December 2014)
Occurrence of ALRTI in infants ≤6 weeks of age and 7 weeks to ≤12 months of age, following the introduction of pertussis maternal immunisation in Bogota, Colombia
