A single dose of ProQuad is approximately 0.5 mL and is administered intramuscularly or subcutaneously. The first dose is usually administered at 12 to 15 months of age but may be given anytime through 12 years of age. <\/p>\n\n\n\n
<\/p>\n\n\n\n
<\/div>\n\n\n\n
The second dose is usually administered at 4 to 6 years of age. At least 1 month should elapse between a dose of a measles-containing vaccine, such as M-M-R\u00ae<\/sup>II<\/sub> <\/span>(Measles, Mumps, and Rubella Virus Vaccine Live), and a dose of ProQuad. At least 3 months should elapse between a dose of varicella-containing vaccine and ProQuad.<\/p>\n<\/div>\n<\/div>\n\n\n\n

For these vaccines, health care professionals have the flexibility to choose the route of administration.<\/strong><\/p>\n\n\n\n
