(CNN) - The American Academy of Pediatrics, along with the Centers for Disease Control and Prevention and the American Academy of Family Physicians, has published a simpler childhood vaccine schedule.
The new report informs parents and doctors of the correct time to vaccinate children against the 16 infectious diseases for which vaccines are available.
The biggest changes to the schedule are that it has been made easier to read, and now recommends that pregnant women receive a whooping cough shot in the second half of their pregnancy.
The rationale behind the change is to vaccinate women near their time of delivery to boost immunity, which then passes through the placenta and get into the baby. This will cause the baby to have its mother's immunity until it can develop its own.
Whooping cough cases have risen to a 50-year high, the CDC said last year.
