Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
MSCs include AEs prompting emergency room or physician visits that are not related to common diseases or routine visits for physical examination or vaccination, or serious adverse events (SAEs) that are not related to common diseases. Common diseases include upper respiratory infections, sinusitis, pharyngitis, gastroenteritis, urinary tract infections, cervico-vaginal yeast infections, menstrual cycle abnormalities and injury.
The pregnancy outcomes were based on reports from pregnant subjects in the study population. Pregnancy outcomes are pregnancies resulting in live births.
Titers were given as geometric mean titers and were measured by Enzyme-linked Immunosorbent Assay (ELISA) and expressed as Enzyme-linked Immunosorbent Assay Units Per Milliliter (EL.U/mL).
Seroconversion is defined as the appearance of anti-HPV-16 and/or anti- HPV-18 antibodies (i.e. antibody titer ≥ cut-off value) in the sera of subjects seronegative before vaccination. Cut-off values were 8 enzyme-linked immunosorbent assay units per milliliter (EL.U/mL) for anti-HPV-16 antibodies and 7 EL.U/mL for anti- HPV-18 antibodies.
Titer given as geometric mean titer (GMT).
The geometric mean and 95% confidence interval of the number of Human Papilloma Virus type 16 (HPV-16) and HPV-18 specific CD4 and CD8 cells producing at least 2 different cytokines is reported per million of CD4 or CD8 T-cells, respectively.
The geometric mean and 95% confidence interval of the number of HPV-16 and HPV-18 specific memory B-cells is reported per million of B-cells. An arbitrary value of 0 was given for subjects with antibody concentration below the limit of quantification.
Cut-off values assessed include 8 enzyme-linked immunosorbent assay units Per Milliliter (EL.U/mL)for anti-HPV-16 antibodies and 7 EL.U/mL for anti-HPV-18 antibodies.
Titers are presented as Geometric Mean Titers (GMTs).
Titers given as Geometric Mean Titers (GMTs). An arbitrary value of 0 was given for subjects with antibody concentration below the limit of quantification.
Pearson coefficients of correlation between serum and CVS for anti-HPV-16 and anti-HPV-18 titers standardized for total IgG were calculated.
Seroconversion was defined as the appearance of antibodies in the serum of subjects seronegative before vaccination. Seronegative subjects are subjects who had an antibody concentration below cut-off value. The assessed cut-off value was 8 ELISA units per milliliter (EL.U/mL).
Antibody titers were expressed as GMTs. The reference cut-off value was greater than or equal to (≥) 8 EL.U/mL.
Antibody titers were expressed as GMTs. The reference cut-off value was greater than or equal to (≥) 8 EL.U/mL.
Seroconversion was defined as the appearance of antibodies in the serum of subjects seronegative before vaccination. Seronegative subjects are subjects who had an antibody concentration below cut-off value. The assessed cut-off value was 7 EL.U/mL.
Antibody titers were expressed as GMTs. The reference cut-off value was ≥ 7 EL.U/mL.
Antibody titers were expressed as GMTs. The reference cut-off value was greater than or equal to (≥) 7 EL.U/mL.

Cervarix is a vaccine being developed for infections caused by human papillomavirus (HPV). It is an investigational product studied in healthy female subjects to assess immunogenicity and safety against papillomavirus infections. The vaccine is in clinical development and has not been reported as approved.
Cervarix is being developed by GSK plc, a biopharmaceutical company listed on the stock exchange under the ticker GSK. The company has conducted multiple clinical trials to evaluate the vaccine's safety and immunogenicity in healthy female participants across various countries.
Cervarix is in Phase 3 clinical development. It has completed five trials, including Phase 2 and Phase 3 studies, with a total enrollment of 2,202 participants. The vaccine remains investigational and is not yet approved for use.
Cervarix has been studied in several completed clinical trials, including NCT00359619, NCT00552279, NCT00996125, and NCT01418937. These trials evaluated the vaccine's immunogenicity and safety in healthy females across different age groups and countries, including the United States, Belgium, Italy, Romania, Slovakia, China, and Brazil.
Cervarix is a vaccine designed to prevent infections caused by human papillomavirus (HPV). It works by stimulating the immune system to produce a protective response against HPV, thereby reducing the risk of infection. The vaccine is administered to healthy females to generate immunity against papillomavirus.
Cervarix is a specific HPV vaccine developed by GSK plc. It is distinct from other HPV vaccines, though it targets the same type of infection. The vaccine has been studied in clinical trials for its immunogenicity and safety profile in healthy female populations.
