The number of vaccines delivered to infants during their early life continues to be a concern.

Vaccines are available that can help prevent meningococcal disease, which is any type of illness caused by Neisseria meningitidis bacteria.

A new study reports some good news regarding when to administer the meningococcal vaccine.

The Centers for Disease Control and Prevention (CDC) recommends a meningococcal conjugate vaccine (Menactra® or Menveo®) for a subgroup of children who are between 2 months and 10 years old if certain criteria are met.

This study is the first to evaluate the safety and immunogenicity of MenACWY-TT when coadministered with diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus virus-Haemophilus influenza type b (DTPa-HBV-IPV/Hib) and pneumococcal conjugate vaccine (PHiD-CV), according to a 3+1 or 2+1 schedule in infants/toddlers.

These researchers said the vaccination with the meningococcal quadrivalent tetanus toxoid conjugate vaccine (MenACWY-TT) can be considered as an alternative option to using monovalent meningococcal vaccines in pediatric immunization schedules.

Additionally, it can be co-administered with the DTPa-HBV-IPV/Hib and 10-valent PHiD-CV vaccines.

This study reported for each DTPa-HBV-IPV/Hib antigen, ≥97.2%, ≥76.5% and ≥97.9% of participants had seropositive/seroprotective levels one-month post-primary vaccination, before the booster dose, and one-month post-booster, respectively.

For each vaccine pneumococcal serotype, ≥74.0% of infants had antibody concentrations ≥0.35 μg/mL at one-month post-primary vaccination, and robust increases in antibody GMCs were observed from pre- to post-booster.

Which means, these results support the co-administration of MenACWY-TT with routine childhood vaccines.

This phase 3 clinical trial NCT01144663 was a randomized, multicenter trial included 2,095 infants. After vaccination, a high percentage of the cohort achieved seroprotective antibody levels for anti-DT, anti-TT, anti-PRP, anti-HBs, and anti-poliovirus types 1, 2, and 3 antibodies for both postprimary (≥97.2%) and post-booster (≥97.9%) administration.
