The assessed solicited administration site adverse events were arthralgia, fatigue, headache, fever and myalgia. Fever was defined as body temperature ≥38.0°Celsius/100.4°Fahrenheit.
An unsolicited AE is defined as an AE that was not included in a list of solicited events using a Participant Diary. Unsolicited AEs include both serious and non-serious AEs.
An SAE is defined as any untoward medical occurrence that, at any dose, resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, caused a congenital anomaly/birth defect, or was any other situation identified according to medical or scientific judgment. An unsolicited SAE is defined as an SAE that was not included in a list of solicited events using a Participant Diary.
An unsolicited AE is defined as an AE that was not included in a list of solicited events using a Participant Diary. The solicited AEs that had an onset after 7 days post each dose administration are considered unsolicited AEs. Unsolicited AEs include both serious and non-serious AEs.
MAE is defined as an AE for which the participant received medical attention defined as hospitalization, an emergency room visit or a visit to or from medical personnel (i.e., nurse practitioner or physician assistant or medical doctor) for any reason.

Pentamer/gB/Adjuvant vaccine is an investigational vaccine being studied for the prevention of Cytomegalovirus (CMV) infections. It is designed to elicit an immune response against the virus in healthy adults. The vaccine is currently in Phase 1 clinical development and has not been approved by regulatory authorities.
Pentamer/gB/Adjuvant vaccine is being developed by GSK plc, a global biopharma company listed on the London Stock Exchange under the ticker GSK. GSK is conducting clinical trials to evaluate the safety and immunogenicity of this investigational CMV vaccine candidate.
Pentamer/gB/Adjuvant vaccine is in Phase 1 clinical development. A Phase 1 trial has been completed, evaluating the safety and immune response to different doses of the vaccine in healthy adults. The vaccine remains investigational and is not yet approved for commercial use.
Pentamer/gB/Adjuvant vaccine has been studied in one completed Phase 1 clinical trial with the identifier NCT05089630. The trial, titled 'A Study of Safety and Immune Response to Different Doses of a Cytomegalovirus Vaccine in Healthy Adults,' enrolled 333 participants in the United States and was placebo-controlled and double-blind.
Pentamer/gB/Adjuvant vaccine is not FDA approved. It is an investigational vaccine currently in Phase 1 clinical development. The completed Phase 1 trial assessed safety and immune response, but the vaccine has not yet received regulatory approval for the prevention of Cytomegalovirus infections.
