The U.S. Centers for Disease Control and Prevention said it is investigating the hospitalizations of five people who recently received a vaccine for the chikungunya virus, which is transmitted via mosquitoes.

In a notice on Tuesday, the CDC said that the five hospitalizations occurred in people aged 65 and older and that they suffered cardiac or neurologic problems after receiving a vaccine known as IXCHIQ.
