Mumps prophylaxis in the light of a new test for antibody
Insights
A radial haemolysis test effectively detects mumps immunity. This method aids in the rational use of mumps immunoglobulin and vaccines, ensuring targeted public health interventions.
Area of Science:
- Immunology
- Virology
- Public Health
Background:
- Mumps immunity is crucial for preventing outbreaks.
- Accurate assessment of immunity guides vaccination and immunoglobulin strategies.
Purpose of the Study:
- To evaluate the radial haemolysis test for assessing mumps immunity.
- To determine immunity levels across different age groups and demographics.
Main Methods:
- Radial haemolysis assay was employed to detect mumps antibodies.
- Testing was conducted on diverse populations including children, adolescents, and pregnant women.
Main Results:
- High antibody prevalence was observed, increasing with age.
- Immunity was detected in a significant percentage of individuals, regardless of reported mumps history.
Conclusions:
- Radial haemolysis is a reliable method for mumps immunity testing.
- Results support informed decisions on mumps-specific immunoglobulin and vaccine administration.
Abstract:
A radial haemolysis test was used to investigate immunity to mumps. Antibody was found in 92 (42%) out of 220 children aged up to 5 years, 124 (78%) out of 159 children aged 6--10 years, 192 (86%) out of 222 children aged 11 years, 138 (92%) out of 150 children aged 15 years, and 280 (95%) out of 296 women attending an antenatal clinic. A group of 307 cadets aged 16--18 years were also tested and interviewed: 133 (95%) out of 140 who said that they had had mumps and 108 (87%) out of 124 who said that they had not had mumps were found to have antibody. The results suggest that tests for immunity to mumps by radial haemolysis would permit more rational use of mumps-specific immunoglobulin and attenuated mumps vaccine.
