The health ministry opened a Kanto-wide RSV antibody appointment window Friday for infants under six months, shifting vials from quieter prefectures as Tokyo pediatric wards reported weekend bed squeezes after Sports Day family gatherings.
Hana Inoue’s health desk said the program uses existing nirsevimab stocks approved earlier this autumn, with clinics in Saitama and Chiba added to the booking portal overnight. Parents must bring maternal vaccination records when available, though absence does not block eligibility.
Why beds tightened
National Institute of Infectious Diseases surveillance showed RSV detections rising two weeks earlier than the five-year average. Tokyo Metropolitan Government hospitals logged occupancy above 85 percent in general pediatric beds Thursday night, prompting transfers to neighboring prefectures.
Mobile clinics deployed to Chiba evacuation shelters after typhoon outages will also carry antibody doses, linking disaster response with routine immunization planning.
What parents should expect
Appointments are grouped by birth month to prevent queue-jumping. Clinics may charge administrative fees not covered by public insurance, typically around 3,000 yen. MHLW promised to publish weekly refill maps so families know which municipalities still have vials.
Inoue will monitor whether the window eases emergency room waits or simply shifts demand to suburban clinics with parking shortages. Either way, the move signals that RSV is treated as a winter readiness issue, not only a post-typhoon footnote.
Pediatric societies asked MHLW to pair the antibody window with clearer guidance on when symptomatic older siblings should stay home from school. The ministry said it would update posters Monday, ahead of expected rain that could keep more families indoors together.
