まとめ
ワクチンに関連した麻痺性ポリオomyelitisは稀であり,ほとんどのケースは,最初の口服ポリオワクチン (OPV) 投与量に関連しています. このリスクは,OPVを投与した後の投与量により,受給者およびその接触者にとって,著しく減少する.
科学分野:

- ワクチン学 ワクチン学
- 公衆衛生は公衆衛生である.
背景:
- ポリオミエライトは依然として公衆衛生上の重要な懸念事項です.
- ワクチン関連麻痺性ポリオomyelitis (VAPP) は,口服ポリオワクチン (OPV) の珍しい合併症である.
研究 の 目的:
- 1973年から1984年の間に米国におけるVAPPの発生率と特徴を分析する.
- VAPPに関連する危険因子,特に最初のOPV用量の役割を決定する.
主な方法:
- 米国で報告された麻痺性ポリオomyelitisの症例の遡及的分析.
- ワクチン接種状況,ワクチン接種者との接触,免疫状態に基づいて症例の分類.
主要な成果:
- 報告された138例のうち105例の麻痺性ポリオomyelitisはワクチンに関連していた.
- VAPP症例の大部分は,OPVの最初の投与後に発生しました.
- VAPPの頻度は,配布された260万個のOPV用量につき1例であり,最初の用量に関連したリスクはより高く (520,000人に1例) であった.
結論:
- VAPPは稀な出来事であり,OPVに関連するリスクは最小限です.
- VAPPの最も高いリスクは,OPVの初期投与と関連しており,その後の投与ではリスクが低下しています.
- これらのリスクを理解することは,現在進行中のポリオ撲滅の取り組みとワクチン政策にとって極めて重要です.

Overview
Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
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.
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
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...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
