Discussion
There was no other symptom or finding inducing the disease in this patient, and bilateral acute severe sensorineural hearing loss developed about 3 weeks after vaccination, suggesting that hearing loss was caused by vaccine side reaction. Regarding severe hearing loss of the bilateral ears caused by vaccine side reaction in other countries, Brodyshy [1] and Gracia [2] reported cases of encephalitis and hearing loss after MMR vaccination. In Japan, Koga [3] reported a case of severe hearing loss of the bilateral ears following development of acute cerebellar ataxia-associated gait disorder which developed after MMR vaccination. Cases of unilateral hearing loss considered a side reaction of mumps vaccine have also been reported [4,5]. Generally, the incubation period of natural measles/rubella virus infection is about 2 weeks, and that of mumps virus is about 2-3 weeks. Measles vaccine was considered the cause based on the incubation period in the case reported by Brodsky, and mumps virus may have been the cause in the case reported by Koga and in our patient. We considered a cerebrospinal fluid test to identify the cause and γglobulin administration as a treatment, but we did not perform these because there was no clinical symptom other than hearing loss and even if mumps is definitely diagnosed, it does not directly lead to treatment. Therefore, it was undesirable to place a burden on the patient. Mumps vaccine is a live vaccine. It has a high affinity to the center and the frequency of inducing aseptic meningitis as a side reaction is higher than those of other vaccines. Since the blood-inner ear barrier is immature so as the blood-brain barrier in infants, hearing loss may be easily caused by mumps virus. Other symptoms, such as encephalitis, developed in other reported cases, but only fever and nausea developed for only one day and no other symptoms developed in our patient, being a rare case. Unfortunately, the side reaction of the vaccine caused serious hearing loss in this patient, but We have no objection against recommendation of vaccination because when the risk of hearing loss caused by the side reaction of the vaccine and the risk of hearing loss and complications, such as aseptic meningitis, caused by natural mumps infection are compared, vaccination to acquire immunity has less risk of complication.

The incidence of hearing loss caused by natural mumps infection has been reported to be 1/1,000- 20,000 [6,7], and the risk of vaccine-induced hearing loss was estimated to be about 1/6-8 million people on a mumps MMR vaccine survey [8]. In view of these reports, although vaccination should be recommended, development of a vaccine with a low frequency of inducing complication is desired.

In the present patient, cochlear implantation was performed in the right ear because hearing ability did not recover after 3-month course observation. Auditory sense was re-acquired by cochlea implantation, and after mapping, an effect sufficient for daily life was acquired. Cochlea implantation is very significant for acquired hearing loss. Affected children are anxious because they became unable to hear immediately after the onset and suddenly lost communication through conversation. Their parents are also anxious seeing that their children suddenly became unable to hear and feel guilty that they decided on vaccination of their children. In the present case, psychological care was performed for the parents and patient involving the pediatric department, and it was explained to the parents that very rare side reaction incidentally occurred and they were not responsible for it. Active care is necessary for not only auditory but also psychological aspects. In addition, it is necessary to cooperate with the governmental office socially for application of certificate for vaccine side reaction so that the patient can receive not only medical assistance but also public aid.

Conclusion
We encountered a child who developed bilateral acute serious hearing loss after receiving simultaneous administration of mumps vaccine and MR vaccine. Based on the incubation period, mumps vaccine was considered the cause. After hearing loss, favorable auditory compensation by cochlea implantation was achieved. For unfortunate side reactions, not only medical care of side reactions but also psychological and social cares with active involvement of physicians are necessary.

Stop allowing them to break us and then to remake us in their image; it is much better to hold the image of God/Christ.
