Kinderarztpraxis Ralph Köllges

The pediatric clinic focuses on evaluating new vaccine candidates that protect children against serious bacterial threats such as meningococcal disease.

• Safety profile of the investigational MenPenta vaccine in infants, toddlers, and young children
• Assessment of immune response to MenPenta compared with existing vaccines
• Measurement of bactericidal activity against serogroups A, C, W‑135, Y, and MenB

These studies are conducted at Kinderarztpraxis Ralph Köllges to ensure that emerging vaccines are both safe and effective for the pediatric population.

Research at the site includes a combined vaccine that targets the four common childhood viral infections, aiming to simplify immunisation schedules.

• Immunogenicity of a combined measles, mumps, rubella and varicella vaccine in children aged 15 months to 6 years
• Evaluation of seroresponse rates and geometric mean concentrations for each virus component
• Comparison of the new formulation with the standard MMRV vaccine to demonstrate non‑inferiority

The trials, overseen by the single investigator at Kinderarztpraxis Ralph Köllges, aim to confirm that the combined vaccine provides robust protection while maintaining a favorable safety profile.
