Insights

Hepatitis B virus (HBV) vaccination coverage in Iran reached high national levels, with over 98% of children receiving all three doses. This indicates successful HBV vaccination program implementation across diverse Iranian populations.

Area of Science:

  • Public Health
  • Vaccinology
  • Epidemiology

Background:

  • Hepatitis B virus (HBV) infection is a significant global health concern.
  • Effective vaccination programs are crucial for controlling HBV transmission.
  • Assessing vaccination coverage is essential for program evaluation and public health planning.

Purpose of the Study:

  • To estimate the national and district-level Hepatitis B virus (HBV) vaccination coverage in Iran.
  • To evaluate HBV vaccination rates across urban, rural, and remote populations.
  • To assess the overall success of the HBV vaccination program in Iranian children.

Main Methods:

  • Cross-sectional study conducted in 2006.
  • Inclusion of 21,905 children from 41 university health service areas in Iran.
  • Data collection based on vaccination card records to determine coverage for HBV doses 1, 2, and 3.

Main Results:

  • National coverage for the 1st, 2nd, and 3rd doses of Hepatitis B virus (HBV) vaccine was 98.9%, 98.8%, and 98.4%, respectively.
  • Vaccination coverage reached 100% for all three doses in several university health areas.
  • The lowest recorded HBV vaccination coverage was 90.7% in a remote district.

Conclusions:

  • Hepatitis B virus (HBV) vaccination coverage in Iranian children is at an acceptable and high level nationally.
  • The findings suggest the successful implementation and reach of the national HBV vaccination program.
  • Continued monitoring is recommended, particularly in remote areas, to maintain high coverage rates.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
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.
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...

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...
