This is a good idea. But I don't think it's enough.
Children under fifteen months should not be allowed to be seen in public until they have been adequately vaccinated. Quarantine from birth to 12 months is reasonable and should be considered. Furthermore, children under the age of four should not be allowed in any large gathering place like an amusement park, water park, church etc. until the age of four, until two doses of the MMR vaccine have been administered.
There's too much risk involved to not be taking this seriously. 600+ cases last year alone in a country of 317 million. This is an epidemic.
