a. Rubella vaccine is given to both boys and girls even though boys do not themselves need suchvaccination
b. Rubella is a relatively mild disease that illustrates vividly the issues that can arise when setting the benefit to the individual against that of thepopulation.
c. In the UK it has until recently been considered that boys do not need vaccinating against rubella and so should not be exposed to the slight risk of vaccine complications; in addition, circulation of wild rubella in the population as a whole is useful in boosting immunity in girls.
d. Therefore thelive attenuated vaccine was given only to girls at adolescence to protect them against developing the disease while pregnant and transmitting it to the fetus,resulting in the congenital rubella syndrome.
