Why is it a good idea to immunize little boys against rubella?
A. As this is a sexually-transmitted disease, vaccinating girls AND boys early in their lives prevents the spread of the disease in adulthood.
B. We want to achieve herd immunity, and there's no reason why only girls would be infected by this virus. By vaccinating the entire population, we achieve a higher degree of herd immunity than is possible by vaccinating only girls.
C. Only boys get this disease, and one of the common complications is sterility.
D. While this disease is quite strikingly symptomatic in girls, it is completely asymptomatic in boys. Boys can be carriers and transmit it easily to girls they are in close proximity to without realizing it through respiratory secretions. This can lead to large-scale and dangerous outbreaks in the female population.
