0.5 mL, single intra-muscular injection
Other names: 13vPnC
Time frame: Baseline up to occurrence of first episode of VT-CAP, death, withdrawal of consent, loss to follow-up, participant request or end of case acquisition defined as accumulation of 130 VT cases (mean follow-up was 3.97 years)
CAP was defined based on clinical and radiological criteria. Microbiological criteria differentiate different categories of CAP. Clinical criteria: presence of 2 or more criteria from following: cough, production of purulent sputum/change in sputum character, temperature greater than (>) 38.0 degrees Celsius (C) or less than (<) 36.1 degrees C, auscultatory findings consistent with pneumonia including rales and/or evidence of pulmonary consolidation, leukocytosis (>10*10^9 white blood cells/liter or >15 percent (%) bands), C-reactive protein level >3 times upper limit of normal, hypoxemia with partial oxygen pressure <60 millimeter of mercury (mmHg). Radiological criteria: pneumonia confirmation by adjudication committee via lateral, posterior-anterior chest x-ray or anterior-posterior chest x-ray. Microbiological criteria: VT Streptococcus pneumonia culture from blood, pleural fluid or other sterile site and/or positive VT serotype-specific urinary antigen detection (SSUAD).
Time frame: Baseline up to occurrence of first episode of NB/NI VT-CAP, death, withdrawal of consent, loss to follow-up, participant request or end of case acquisition defined as accumulation of 130 VT cases (mean follow-up was 3.97 years)
CAP was defined based on clinical and radiological criteria. Microbiological criteria differentiate different categories of CAP. Clinical criteria: presence of 2 or more criteria from following: cough, production of purulent sputum/change in sputum character, temperature >38.0 degrees C or <36.1 degrees C, auscultatory findings consistent with pneumonia including rales and/or evidence of pulmonary consolidation, leukocytosis (>10*10^9 white blood cells/liter or >15% bands), C-reactive protein level >3 times upper limit of normal, hypoxemia with partial oxygen pressure <60 mmHg. Radiological criteria: pneumonia confirmation by adjudication committee via lateral, posterior-anterior chest x-ray or anterior-posterior chest x-ray. Microbiological criteria: Confirmed VT pneumococcal CAP (by SSUAD) where a blood culture result was available and was negative and for which any other sterile culture results were negative for Streptococcus pneumoniae.
Time frame: Baseline up to occurrence of first episode of VT-IPD, death, withdrawal of consent, loss to follow-up, participant request or end of case acquisition defined as accumulation of 130 VT cases (mean follow-up was 3.97 years)
VT-IPD was defined as the presence of Streptococcus pneumoniae in a sterile site (blood, cerebrospinal fluid, pleural fluid, peritoneal fluid, pericardial fluid, surgical aspirate, bone, or joint fluid).
Time frame: Within 7 days after vaccination
Local reactions were reported using electronic diary (e-diary). Redness and swelling scaled as Any (redness or swelling present); Absent (no or minimal); Mild (2.5 centimeter [cm] to 5.0 cm); Moderate (5.1 to 10.0 cm); Severe (>10.0 cm). Pain scaled as Any (pain present); Mild (did not interfere with activity); Moderate (interfered with activity); Severe (prevented daily activity). Limitation of arm movement scaled as Any (limitation present); Absent (no limitation of arm movement); Mild (some limitation of arm movement); Moderate (unable to move arm above head, but able to move arm above shoulder); Severe (unable to move arm above shoulder). Percentage of participants with local reactions were reported. Participants may be represented in more than 1 category.
Time frame: Within 7 days after vaccination
Systemic events (fever, fatigue, headache, chills, rash, vomiting, decreased appetite, diarrhea, new generalized muscle/joint pain [new muscle/joint pain], aggravated generalized muscle/joint pain [aggravated muscle/joint pain], use of medication to treat pain/fever) reported using an e-diary. Fever scaled as Absent(<38 degrees C); Mild(greater than or equal to [>=]38 to <38.5 degrees C); Moderate(>=38.5 to <39 degrees C); Severe(>=39 to less than or equal to [<=]40 degrees C); Potentially life threatening (>40 degrees C). Fatigue, headache, new/aggravated muscle/joint pain scaled as Mild(no interference); Moderate(some interference); Severe(prevented routine activity). Vomiting scaled as Mild(1-2 times in 24 hours [hrs]); Moderate(>2 times in 24 hrs); Severe(required intravenous hydration). Diarrhea scaled as Mild(2-3 loose stools in 24 hrs); Moderate(4-5 loose stools in 24 hrs); Severe(>=6 loose stools in 24 hrs). Percentage of participants with systemic events were reported.
Time frame: From signing of informed consent form up to case acquisition period defined as accumulation of 130 VT cases (mean follow-up was 3.97 years)
Deaths collected throughout the case acquisition period were presented.
Time frame: From 1 month after vaccination up to 6 months after vaccination
Percentage of participants with newly diagnosed chronic medical conditions (including autoimmune or neuroinflammatory disease) in the immunogenicity subset were reported as per planned analysis.
