I have written synopses of the childhood viral diseases Measles and Rubella.
The take away information - children between 12 and 15 months of age should receive the MMR vaccine, with a booster at least 4 weeks later or by the time they enter Kindergarten (4-6 years of age) to confirm immunity.
Women who are planning on getting pregnant should be tested for Rubella to ensure their immunity. Those who are not immune should be vaccinated for Rubella at least 28 days prior to becoming pregnant to prevent birth defects. 25% of women who are susceptible to rubella and exposed to the virus in their first trimester have babies with eye defects, heart defects, hearing loss, mental impairments, and movement disorders.
