Insights

Routine immunization coverage for under-five children shows high initial vaccine uptake but declines for boosters. Strengthening immunization services beyond infancy is crucial for complete childhood vaccination.

Area of Science:

  • Pediatrics
  • Public Health
  • Vaccinology

Background:

  • Childhood immunization is critical for preventing infectious diseases.
  • Underserved populations often face barriers to accessing complete immunization services.
  • Assessing routine immunization coverage is essential for public health planning.

Purpose of the Study:

  • To determine routine immunization coverage rates in under-five children in two underserved areas.
  • To provide health education on the importance of complete immunization.
  • To identify gaps in immunization schedules.

Main Methods:

  • A cross-sectional study was conducted using interviews.
  • The study included 2,531 children under five and their caregivers.
  • Data were collected from hospital and outreach sessions in Aligarh city.

Main Results:

  • High initial coverage for first doses of Diphtheria, Pertussis, Tetanus (DPT) and Oral Polio Vaccine (OPV), and Bacillus Calmette-Guerin (BCG).
  • Coverage decreased significantly for second and third doses of DPT and OPV.
  • Measles and DPT booster vaccine coverage was notably low in both study areas.

Conclusions:

  • While initial vaccination is high, sustained immunization efforts are needed.
  • Immunization services require enhancement, particularly for booster doses and older infants.
  • Targeted health education and improved service delivery can increase complete immunization rates.

Methods Of Healthcare Delivery System

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

Primary Healthcare Services01:30

Primary Healthcare Services

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

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.

Specialized Care Centers and Settings-II

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
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...
