Symptom narrative

This is haunting me and has really gotten me worried that the vaccine might not be as effective.; My concern is that the second time the nurse didn't shake the syringe and I also forgot to remind her.; This spontaneous report was received from a 32-year-old female patient. The patient's medical history, concurrent conditions and concomitant therapies were not reported. On an unknown date, the patient was vaccinated with the second dose of Human Papillomavirus 9-valent Vaccine, Recombinant (GARDASIL 9) (strength, dose, route of administration, lot # and expiration date were not reported) as prophylaxis, which was really difficult for her to purchase due to financial issues. But she decided to put her health and safety first despite everything. Her concern was that the second time the nurse didn't shake the syringe and the patient also forgot to remind her (Product preparation issue). It said on the package to "shake well before use". This was haunting the patient and had really gotten her worried that the vaccine might not be as effective (Worry). At the reporting time, the outcome of Worry was unknown. The action taken was not applicable. The causal relationship between the event of Worry and Human Papillomavirus 9-valent Vaccine, Recombinant (GARDASIL 9) was not reported. Lot # is being requested and will be submitted if received.
