Outcome Measures

Primary Outcomes (3)

  • Number of Seasonal Influenza A and /or B Cases by Age Group, in Panama (Using the Data Reported Via National Influenza Surveillance Program)

    The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years and Unspecified age, instead of \<1, 1-4, 5-9, 10-14, 15-19, 20-24, 25-44, 45-49, 50-59, 60-64 and ≥ 65 years, as initially described in the Protocol. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.

    From January 2011 to December 2017

  • Number of Seasonal Influenza A Cases by Virus Subtypes, in Panama (Using the Data Reported Via National Influenza Surveillance Program) Among All Influenza Cases A and/or B

    The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by virus subtype (H1N1 and H3N2) and the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.

    From January 2011 to December 2017

  • Number of Seasonal Influenza B Cases by Strain Lineage, in Panama (Using the Data Reported Via National Influenza Surveillance Program) Among All Influenza Cases A and/or B

    The case definition of Influenza was any clinical specimen confirmed by a positive laboratory test. Cases were stratified by lineage (Victoria and Yamagata) and the following age categories: less than (\<) 2 years; 2-4 years; 5-19 years; 20-39 years; 40-59 years; greater than of equal to (≥) 60 years. Note that one specimen sample was positive for both influenza A and B so the number started still remains 1839.

    From January 2011 to December 2017

Secondary Outcomes (6)

  • Number of Cases With Laboratory Confirmed Diagnosis Seasonal Influenza A and/or B Who Experienced Clinical Features (Clinical Symptoms)

    From January 2011 to December 2017

  • Number of Cases With Laboratory Confirmed Diagnosis Seasonal Influenza A and/or B Who Experienced Outcomes (Complications)

    From January 2011 to December 2017

  • Number of Seasonal Influenza A and /or B Cases by Southern Hemisphere, Within Different Seasons From 2011 to 2017

    Within the Southern hemisphere influenza seasons (May to October of each year 2011-2017)

  • Number of Seasonal Influenza A and /or B Cases by Region, Within Study Period From 2011 to 2017

    From January 2011 to December 2017

  • Number of Influenza Cases Caused by B- Strain and Presented by B-lineage and by Region Among All Influenza Cases A and/or B

    From January 2011 to December 2017

  • +1 more secondary outcomes

Study Arms (1)
