Solicited local symptoms were pain, redness and swelling at the injection site. Any = occurrence of a symptom regardless of intensity.
Solicited general symptoms were arthralgia, fatigue, headache, muscle aches, shivering and temperature, assessed as oral temperature above or equal (≥) 38.0 degrees Celsius (°C). Any = occurrence of a symptom regardless of intensity or relationship to vaccination.
Medically-attended events (MAEs) refer to non-serious and serious events leading to an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits and hospitalization. Related MAE = MAE assessed by the investigator as related to the vaccination.
NOCDs include conditions such as autoimmune disorders, asthma, type I diabetes, or allergies.
Unsolicited AEs cover any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any unsolicited AE = any unsolicited AE regardless of intensity or relationship to vaccination.
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Any SAE = any SAE regardless of intensity or relationship to vaccination.
Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
A seroprotected subject was defined as a vaccinated subject with a serum HI antibody titer ≥ 1:40, a level of HI antibody that has been viewed as correlating with protection against influenza. The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer \<1:10 and a post-vaccination titer ≥1:40 or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
GMFR was defined as the geometric mean of the ratio of the post-vaccination inverse HI titer to the Day 0 inverse HI titer. The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)

Trivalent influenza vaccine GSK 138842A is an investigational vaccine being developed for the prevention of influenza. It is designed to provide immunity against three influenza virus strains. The vaccine is currently in Phase 1 clinical development and is not yet approved for public use.
Trivalent influenza vaccine GSK 138842A is being developed by GSK plc, a global biopharma company listed on the stock exchange under the ticker GSK. The company is conducting clinical trials to evaluate the vaccine's safety and immune response in adult participants.
Trivalent influenza vaccine GSK 138842A is in Phase 1 clinical development. It is an investigational vaccine, meaning it has not been approved by regulatory authorities. The Phase 1 trial has been completed, and the vaccine is still undergoing clinical evaluation.
Trivalent influenza vaccine GSK 138842A has been studied in one completed Phase 1 clinical trial, identified as NCT00693706. This randomized, double-blind, active-controlled study enrolled 200 healthy adults aged 18 years and older in the United States to evaluate the vaccine's safety and immune response compared with Fluarix.
Trivalent influenza vaccine GSK 138842A is also referred to as GSK 1388442A in clinical trial documentation. The Phase 1 study NCT00693706 lists the vaccine as GSK Biologicals' Influenza Virus Vaccine 1388442A, indicating that these names refer to the same investigational vaccine.
