Vaccination against rubella in Britain: benefits and risks
Developments in Biological Standardization
|January 1, 1979
Summary
Rubella vaccination programs impact congenital rubella rates differently. Early childhood vaccination offers faster protection, while adolescent vaccination shows slower but sustained benefits for women
Area of Science:
- Immunology
- Public Health
- Vaccinology
Background:
- Rubella vaccination strategies vary, influencing their effectiveness and risks.
- Congenital rubella syndrome (CRS) prevention is a key public health goal.
- The age of vaccination impacts the development and durability of rubella immunity.
Purpose of the Study:
- To evaluate the effectiveness of different rubella vaccination programs on rubella incidence.
- To compare the benefits and risks associated with various rubella immunization schedules.
- To analyze the impact of vaccination timing on population immunity and CRS rates.
Main Methods:
- Comparative analysis of rubella vaccination program outcomes.
- Review of epidemiological data on rubella incidence and congenital rubella.
- Assessment of antibody seropositivity trends in vaccinated populations.
Main Results:
- Vaccinating 11-13 year old girls showed delayed impact on congenital rubella but increased seropositivity in women.
- In Britain, vaccination of 13-year-old girls led to increased rubella antibody seropositivity and reduced pregnancy terminations for rubella.
- Pre-school vaccination of boys and girls demonstrated more rapid effects in shielding pregnant women but relied on vaccine-induced immunity.
Conclusions:
- Rubella vaccination programs' effectiveness depends on the adopted schedule.
- Early childhood vaccination provides quicker protection but requires durable immunity.
- Risks associated with rubella vaccine are generally low, increasing slightly with age.

Overview
01:22Development 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...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
01:24Smallpox
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.
01:29Respiratory 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...
