You are seeing a 2.5 month old baby who underwent a fever work-up yesterday and has been called back due to a positive blood culture growing gram positive cocci in clusters. The baby received the first set of immunizations at age 7 weeks. The baby is afebrile today and has been doing well and eating normally. The only treatments have been acetaminophen, last given 8 hours ago.

Which of the following is true?
