Mr. Spritzer asks for a sick certificate as he has taken a day off work because of a cold. He has brought his son Ben with him because his wife is working. She had mentioned something about Ben’s injections being late. You learn that Ben had his injections aged 2 months and there was still a lump in his right thigh. Ben is now 5 months old. Mr. Spritzer's wife had expressed concerns about the next immunisation as Ben had also been sick for a little while after the previous shot and today Ben had a temp. of 37.6° C.
