###Human: When can birth vaccine be delayed in a newborn? ###Assistant: Hi. I understand your concern. Vaccines are given as the birth age for a full-term normal weight baby. If the baby was premature and hospitalized, then it can be delayed. If it is delayed then one month gap is usually kept between two vaccines for better vaccine uptake. You are right, your baby's next dose schedule is around 1 or 2 of this month. There must be a reason for the delay, as I mentioned earlier. In the long run, it usually does not make a lot of difference. Make sure all the necessary vaccines are received.
