Insights

Maternal measles antibody levels are low, impacting newborns. Early infant vaccination at six months may improve protection against measles, reducing illness in infants.

Area of Science:

  • Immunology
  • Pediatrics
  • Vaccinology

Context:

  • Maternal antibody transfer is crucial for infant immunity.
  • Measles antibody levels in mothers and newborns are often insufficient for sustained protection.
  • Infant vaccination schedules aim to establish protective immunity before maternal antibodies wane.

Purpose:

  • To assess measles IgG antibody levels in mothers and newborns.
  • To evaluate the correlation between maternal and infant measles antibody titers.
  • To determine the efficacy of current infant measles vaccination schedules at 6 and 8 months.
  • To inform measles control strategies for infants.

Summary:

  • Measles IgG antibody levels were measured in 58 mother-newborn pairs using ELISA.
  • Newborns showed low initial measles antibody levels that declined significantly by 3, 6, and 8 months.
  • Vaccination success rates and antibody distribution were similar in 6- and 8-month-old infants, but overall antibody levels remained low, offering minimal protection.
  • Maternal measles antibody levels were generally low, correlating with infant levels.

Impact:

  • Low maternal antibody levels necessitate improved infant immunization strategies.
  • Vaccinating mothers may enhance neonatal measles antibody levels.
  • Shifting the primary measles vaccination age to 6 months could reduce infant measles morbidity in specific regions.

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.
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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
Vaccines01:21

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
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...
