In this CHOC Radio segment, Dr. Antonio Arrieta discusses proper timing of vaccinations, dispels myths surrounding vaccinations, and details his current research at CHOC. Listen in to hear more about childhood vaccinations.
Symptoms of pneumonia can include fever and cough, and in the very young, those may be the only symptoms. In older children, you will notice their respiratory rates go up because they need to oxygenate their blood so they breathe more often.
Clinical trials are research projects that involves patients. Doctors conduct these trials to find out how good the drugs are or how best to use them.
When late fall rolls around, the flu usually rolls in with it. A cough, a high fever and sore throat are early signs of influenza.
