[Immunity reaction in old age (author's transl)]
Summary
Older adults often lack protective tetanus antitoxin levels. Immunization with tetanus toxoid shows a diminished antibody response in elderly individuals compared to younger populations.
Area of Science:
- Immunology
- Gerontology
- Vaccinology
Context:
- Ageing is associated with a decline in immune function.
- Tetanus remains a public health concern, necessitating robust immunity.
Purpose:
- To assess tetanus antitoxin levels in an elderly cohort.
- To evaluate the immunogenicity of tetanus toxoid vaccination in older adults.
Summary:
- A significant proportion (61%) of individuals aged 73 years lacked protective tetanus antitoxin concentrations.
- Active immunization with tetanus toxoid resulted in a slower and lower increase in tetanus antitoxin levels in the elderly compared to younger individuals.
Impact:
- Highlights potential vulnerability of the elderly to tetanus.
- Suggests a need for optimized vaccination strategies in ageing populations.
