They got a bad batch of vaccine or some of it got contaminated at some point.
The whole point of vaccination is to generate an immuno response, sometimes that means you’re going to get a little sick from it.
Only one in about 900 of the 1.8m kids vaccinated in a 4 year period with that specific vaccine reported unwanted/unexpected side effects and only a tiny handful developed any serious problems such as meningitis. They were all successfully treated.
Japan has since adopted monovalent vaccines for all three diseases.
There has been some controversy associated with the implementation of the MMR vaccine in Japan. The possible side effects of the vaccine include mild issues such as allergic reaction, fever, rash and swelling of the cheeks or neck; as well as more serious concerns, such as seizures, joint pain and hearing loss. Despite the side effects, the vaccine was adopted for widespread use by developed nations around the globe. It is important to note that there are risks associated with any vaccine. Japan, however, reported several cases of non-viral meningitis and other adverse reactions in the 1.8 million children or more who had been immunized during a four-year period. This equates to approximately one in every 900 children reportedly experiencing negative reactions. These results, as well as growing public opposition to the vaccine, eventually led the Ministry of Health, Labour and Welfare to ban the MMR vaccine in Japan in 1993. A ban that remains to this day as the agency awaits the development of a combined vaccine they consider safer.
But if you have a baby in Japan, can your child still get vaccinated against these diseases? The answer is yes. While the original MMR vaccine was banned in 1993, after a second version was trialled in 1991, the individual vaccines for measles, mumps and rubella remain available to parents looking to immunize their children, which means that the vaccine can be administered separately in Japan if desired. The estimated cost of which is listed below.

If you’re interested in having your child vaccinated, speak with your physician about the options available. The King Clinic in Omotesando specializes in immunizations and vaccinations. If you live in Yokohama, Ocean Clinic can also cover all your vaccination needs. Not all vaccines are included in the national immunization program, so it is important to be specific about which shots you would like your child to have. Unfortunately, this may mean more out-of-pocket costs for parents. If you’re not covered by the Japan National Health Insurance (NHI) program, please check with your insurance provider of any additional costs.
