An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Per protocol, the percentage of participants with solicited injection-site AEs was assessed for up to \~14 days after each vaccination. The solicited injection-site AEs assessed were erythema/redness, induration/hard lump, tenderness/pain and swelling.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Per protocol, the percentage of participants with solicited systemic AEs was assessed for up to \~14 days after each vaccination. The solicited systemic AEs assessed were appetite lost/decreased appetite, irritability, drowsiness/somnolence and hives or welts/urticaria.

An SAE is any untoward medical occurrence that results in death, is life-threatening, requires or prolongs existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgement. Relatedness of an SAE to the study vaccine was determined by the investigator. Per protocol, the percentage of participants with vaccine-related SAEs was assessed through 6 months following Vaccination 4.

The GMC of anti-PnP serotype-specific IgG for 13 shared serotypes contained in V114 and Prevnar 13™ (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F) was assessed using a pneumococcal electrochemiluminescence (PnECL) assay. Per protocol, 13 IgG serotypes in Groups 2, 3, 4 (experimental arms) were compared to Group 1 (comparator arm) at 30 days post Vaccination 4 as a pre-specified primary outcome analysis; 13 IgG serotypes in Group 5 (experimental arm) were compared to Group 1 (comparator arm) at 30 days post Vaccination 4, as a separate protocol-specified secondary outcome analysis and reported later in the record.

An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

An injection site adverse event (AE) includes the following AEs at the injection site: redness, swelling, and pain/tenderness.

Systemic adverse events (AEs) include, but are not restricted to the following AE terms: muscle pain, joint pain, headache, and tiredness.

A serious adverse event (SAE) is any adverse event occurring at any dose or during any use of Sponsor's product that: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is another important medical event; is a cancer; or is associated with an overdose.

The investigator determined whether the SAE or death was related to vaccine treatment.

Vaccine-induced functional antibodies to serotypes 22F and 33F, which are unique to PNEUMOVAX™ 23, were measured by the multiplex opsonophagocytic activity 4 (MOPA-4) assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

Vaccine-induced functional antibodies to serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, which are contained in both Prevnar 13™ and PNEUMOVAX™ 23, were measured by the MOPA-4 assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure.
