Massachusetts Citizens for Vaccination Choice

For information on these diseases and the MMR vaccine, visit the National Vaccine Information Center’s MMR webpage.

Of note is the fact that the second dose of MMR is required of 100% of children because 5% do not show sufficient measles antibodies after the first administration. If your child is in the 95% that appears to have sufficient antibodies, s/he is not required by law to receive this second dose. You may consider having your child’s blood tested (titred) to determine if a second dose of measles vaccine is recommended.

MCVC would always recommend, should you decide to vaccinate your child, that vaccines be administered separately when possible. Though it is becoming increasingly difficult to get traditionally ‘trivalent’--or shots with three different vaccines in them, like MMR--vaccines separated, you might find some assistance at the bottom of our MDs & Others page.
