Number of participants with solicited local AEs will be reported. Solicited local AEs (pain/tenderness, erythema, and swelling at the injection site) and will be noted in the participant diary for 14 days post-vaccination.

Number of participants with solicited systemic AEs will be reported. Solicited systemic AEs (oral body temperature, headache, fatigue, nausea, and myalgia) will be noted in the participant diary for 14 days post-vaccination.

Number of participants with unsolicited AEs will be reported. Unsolicited AEs are all AEs for which the participant is not specifically questioned in the participants diary.

Number of participants with SAEs will be reported. A SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life threatening experience, is a congenital anomaly/birth defect, is suspected transmission of any infectious agent via a medicinal product, is medically important, and may jeopardize participant or may require medical or surgical intervention to prevent one of the outcomes listed above.

Number of participants with solicited local AEs for 14 days after vaccination on Day 1 were reported. An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the study vaccine. Solicited local AEs were precisely defined events that participants were specifically asked about and which were noted by participants in the diary. Solicited local (injection site) AEs included injection site pain/tenderness, erythema and swelling at the study vaccine injection site, were used to assess the reactogenicity of the study vaccine and were pre-defined local (injection site). All solicited AEs at the injection site (local) were considered related to the study vaccine administration.

Solicited systemic AEs included fatigue, headache, nausea, fever and myalgia, for which participants were specifically questioned and which were noted by participants in their participant diary for 14 days post-vaccination (day of vaccination and the subsequent 14 days).

Number of participants with unsolicited AEs up to 29 days after vaccination on Day 1 were reported. An AE was any untoward medical occurrence in a clinical study administered a medicinal (investigational or non-investigational) product.
