An AE was any untoward medical occurrence in a participant or in a clinical investigation participant administered a medicinal product and which did not necessarily have a causal relationship with this treatment. Immediate events were recorded to capture medically relevant unsolicited systemic AEs (including those related to the product administered) that occurred within the first 30 minutes after vaccination. An unsolicited AE was an observed AE that did not fulfill the conditions prelisted in the case report book (CRB) in terms of diagnosis and/or onset window post-vaccination and included both serious adverse events (SAEs) and non-serious unsolicited AEs.

A solicited reaction was an "expected" adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) prelisted in the protocol and CRB and were considered to be related to the product administered. An injection site reaction was an adverse reaction at and around the injection site which were commonly inflammatory reactions. Solicited injection site reactions included tenderness, erythema and swelling around the injection site and were planned to be collected and reported for SP0202/Prevnar 13 for both toddlers and infants.

A solicited reaction was an "expected" adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) pre-listed in the protocol and CRB and considered as related to the product administered. Solicited systemic reactions included fever, vomiting, abnormal crying, drowsiness, appetite loss, and irritability. Reported AEs for each arm were presented as pre-specified in protocol.

Unsolicited AEs included both SAEs and non-serious unsolicited AEs. Reported AEs for each arm were presented as pre-specified in protocol.

An SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event. An AESI (serious or non-serious) was defined as one of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and rapid communication by the Investigator to the Sponsor was appropriate. The following AE were captured as AESI throughout the study: Anaphylaxis defined as per the Brighton collaboration case definition, convulsions including febrile convulsions, hypotonic-hyporesponsive episode and apnea. Reported AEs for each arm were presented as pre-specified in protocol.

The GMCs for serotype specific pneumococcal IgG antibodies were measured using pneumococcal capsular polysaccharide-electro-chemiluminescent assay (PnPS-ECL), a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.

Percentage of infants with serotype specific IgG concentration \>=0.35 mcg/mL for each pneumococcal serotype included in the SP0202 formulations were measured using ECL, a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.

The GMCs for serotype-specific pneumococcal IgG antibodies were measured using PnPS-ECL, a multiplexed serological assay which allows for the simultaneous quantification of human IgG against pneumococcal polysaccharide antigens.
