What respiratory monitoring precaution applies to infants born at or before 28 weeks of gestation receiving primary vaccination with Infanrix-IPV+Hib?

For infants born at ≤28 weeks receiving primary Infanrix-IPV+Hib vaccination, consider apnoea risk and respiratory monitoring for 48–72 hours, particularly with previous respiratory immaturity; vaccination should not be withheld or delayed because its benefit is high in this group.
