Patient has no allergies, and confirmed that she had no prior known reactions to vaccines. Patient returned on 5/7/25 for another previously scheduled appointment, and reported that she had some redness/swelling at the injection site starting on 4/30/25 until Saturday, 5/3/25. Patient also reported having rash, itchiness, tiredness, and nausea (without vomiting) during this time period. Patient stated that she took Claritin, which helped her symptoms.
