まとめ
ワクチン接種反対運動は, pertussis (百日咳) の発生率を大幅に増加させた. 高いディフテリア・テタヌス・百日咳 (DTP) ワクチン接種率を維持することで,百日咳の症例が大幅に減少し,ワクチンの有効性を強調しています.

背景:
- 抗ワクチン運動は,歴史的に,全細胞 pertussis ワクチンをターゲットにしています.
- ワクチン接種を躊躇することは,免疫接種率の低下とワクチン接種で予防可能な病気の発生につながる可能性があります.
研究 の 目的:
- ワクチン接種反対運動が pertussis の発生率に与える影響を評価する.

主な方法:
- pertussis 発症率に関するデータの比較分析.
- 各国は,DTPワクチンの接種率 (ワクチン反対運動によって維持されたか,中断されたか) に基づいてグループ化されました.
- ワクチン接種率が異なる近隣諸国も比較した.
主要な成果:
- 百日咳の発生率は,高いDTPカバーを維持している国では10~100倍低かった.

Overview
Active versus Passive Immunity
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.

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...
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.
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 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...
