If your baby was born early or at a low birth weight, it’s normal to wonder whether vaccines should follow a different schedule. Get clear, personalized guidance on vaccine timing, weight-related considerations, and what questions to discuss with your baby’s clinician.

Parents often search for a birth weight vaccine schedule for premature babies because they want to know whether vaccines should be delayed until a baby reaches a certain size. In many cases, routine infant vaccines are based more on chronological age than weight, but there can be important exceptions, especially for very low birth weight infants or babies with ongoing medical needs.
