(WHAS11) -- The American Academy of Pediatrics, along with the Centers for Disease Control and Prevention and the American Academy of Family Physicians published a new, simpler childhood vaccine schedule on Wednesday.
It tells parents and doctors when is the correct time to vaccinate children against the 16 infectious diseases for which vaccines are available.
The change makes the schedule easier to read and another big change applies to pregnant women.
Now it's recommended that pregnant women receive a whooping cough shot in the second half of their pregnancy to vaccinate women near their time of delivery to boost immunity, which then passes through the placenta and get into the baby - so the baby will have its mother's immunity until it can develop its own.
According to the CDC, whooping cough cases have risen to a 50-year high.
