The patient came to the pharmacy after receiving four other vaccinations from the travel clinic. She then received the Chikengunya vaccine and stated she felt fine. We walked from the vaccination room back to the pharmacy where she stood for a few minutes before proceeding to the counter to receive other travel medications. When she was checking out, she stated that she felt faint and the pharmacist came around the counter to help in case she passed out, which she did. She fell faster than the pharmacist could react and the patient hit her head on the counter with no obvious signs of trauma from the impact. We placed her on the floor until she regained consciousness. She sat in a chair for about 30 minutes and a rapid response was called. She was checked out by a couple of nurses, cleared, and left the pharmacy that day.
