1 month usually means at or after baby turns 1 month old. If you’re late for any of them, they will adjust the schedule to let you catch up. If you’re keen for the rotavirus vaccine (optional), the 2 doses (1 month apart) need to be completed before 6 months of age.
For some vaccines, polyclinic nurse does indicate when is the latest to take. 1 month means after baby turns 1 month old, etc.
