A recent measles exposure at the Cincinnati/Northern Kentucky International Airport has Louisville medical experts warning parents.

The parents received a phone call from the pharmacy 90 minutes later telling them that a mistake was made.

A "Protest for Medical Freedom" was held outside Baptist Health Hardin in Elizabethtown Wednesday morning.

They want to answer questions about the vaccine, something they hope could lead to protecting more people.

According to the Centers for Disease Control and Prevention, vaccine orders are down 14% in 2020-21 compared to 2019. The vaccine for measles is down 20%.
