Insights

Preterm infants demonstrate robust antibody responses to pertussis, Hib, and poliovirus vaccines. The Hiberix vaccine shows high immunogenicity, supporting its inclusion in routine infant immunization schedules.

Area of Science:

  • Immunology
  • Vaccinology
  • Pediatrics

Context:

  • Preterm infants often exhibit altered immune responses.
  • Assessing vaccine immunogenicity in preterm populations is crucial for public health.
  • Standard immunization schedules require evaluation for vulnerable infant groups.

Purpose:

  • To determine antibody levels against Bordetella pertussis, Haemophilus influenzae type b (Hib), and Poliovirus type 1 in preterm infants.
  • To evaluate the immunogenicity of acellular pertussis (Infanrix-DTPa), Hib conjugate (Hiberix), and inactivated poliovirus (Imovax Polio) vaccines.
  • To assess seroconversion rates and post-vaccinal antibody titers in preterm infants.

Summary:

  • A study involving 32 preterm infants assessed antibody levels post-vaccination with Infanrix-DTPa, Hiberix, and Imovax Polio.
  • High seroconversion rates (100% for pertussis and Hib, 95% for polio) were observed after three vaccine doses.
  • Statistically significant increases in antibody titers were noted for all antigens, with no correlation to birth weight or gestational age.

Impact:

  • The findings support the efficacy of Infanrix-DTPa, Hiberix, and Imovax Polio in preterm infants.
  • Hiberix demonstrated high immunogenicity, recommending its incorporation into standard vaccination protocols for preterm infants.
  • This research contributes to optimizing vaccination strategies for preterm infants to ensure adequate protection against preventable diseases.

Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
