A Phase 2 interventional study of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid Conjugate Vaccine and Meningococcal Polysaccharide groups A, C, W-135 and Y Conjugate Vaccine in Meningitis, Meningococcal Meningitis and Meningococcal Infections, sponsored by Sanofi Pasteur, a Sanofi Company. Completed at 8 sites in Finland. Open to participants aged 12 Months to 23 Months, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-04-04.
Sponsored by Sanofi Pasteur, a Sanofi Company · Phase 2, Interventional, and Prevention
The purpose of the study was to evaluate the immunogenicity and safety profile of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid (MenACYW) Conjugate vaccine when given alone compared to that of the licensed Meningococcal groups A, C, W 135 and Y (NIMENRIX®) Conjugate vaccine.
Observational objectives:
All participants received 1 dose of MenACYW Conjugate vaccine or NIMENRIX® on Day 0 and were evaluated for immunogenicity and safety profile. The duration of each participant's participation in the trial was 30 to 44 days.
219 studies on the registry are indexed under Meningococcal Infections; 6 are open to participants now.
This study's enrollment of 188 is below the median of 450 across 190 interventional studies indexed under Meningococcal Infections.

Number of Participants Reporting Solicited Injection-Site and Systemic Reaction Following Vaccination With Either MenACYW Conjugate Vaccine or NIMENRIX®
A solicited reaction was defined as an adverse reaction (AR) observed and reported under the conditions (symptom and onset) prelisted (i.e., solicited) in the case report form (CRF) and considered as related to vaccination. Solicited injection site reactions: Tenderness, Erythema, and Swelling. Solicited systemic reactions: Fever, Vomiting, Crying abnormal, Drowsiness, Appetite lost, and Irritability. Grade 3 solicited injection site reactions: Tenderness: cries when injected limb was moved or the movement of the injected limb was reduced; Erythema and Swelling: greater than or equal to (≥) 50 millimeter (mm). Grade 3 solicited systemic reactions: Fever: greater than \[\>\] 39.5 degree Celsius (°C); Vomiting: ≥6 episodes per 24 hours or requiring parenteral hydration; crying abnormal: \>3 hours; Drowsiness: sleeping most of the time or difficult to wake up; Appetite lost: refuses ≥3 feeds or refuses most feeds; Irritability: inconsolable.
Time frame: Day 0 up to Day 7 post-vaccination
Study participants were enrolled from 31 March 2015 to 17 July 2015 at 8 clinic centers in Finland.

Collected over Unsolicited adverse events (AEs) data were collected from Day 0 up to Day 30 post-vaccination. The solicited reactions (SRs) were collected up to Day 7 after vaccination. Serious AEs were collected throughout the trial (up to 30 days after vaccination).. Non-serious events are listed at a 5% frequency threshold.
