The occurrence of additional non-serious events is detailed below.     Previously administered products included for Product used for unknown indication: Pfizer (First dose, lot number EL9265) on 12-Feb-2021, Pfizer (2nd dose, lot number EN6203) on 04-Mar-2021, Pfizer (1st booster, lot number 301358A) on 04-Oct-2021 and flu shot (Aug2021 or Sep2021). Past adverse reactions to the above products included No adverse event with Pfizer, Pfizer, Pfizer and flu shot. Concurrent medical conditions included Pollen allergy (she already had for the last 10-12 years) and Cervical neuritis.    On 10-Apr-2022, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. In April 2022, the patient experienced NECK PAIN (horrible neck pain\pain was terrible), ILLNESS (she got horribly sick again for 24 hours) and HEADACHE (headache). On an unknown date, the patient experienced CERVICAL RADICULOPATHY (inflammation of cervical spine nerves dermatome affected (right shoulder, arm forehead and neck) aggravated), FEELING COLD (so cold that she wore clothes to bed), CHILLS (chills), FATIGUE (fatigue), NAUSEA (nausea) and INAPPROPRIATE SCHEDULE OF PRODUCT ADMINISTRATION (First 3 doses of Pfizer then received Moderna vaccine). The patient was treated with IBUPROFEN at a dose of 400-600mg. At the time of the report, NECK PAIN (horrible neck pain\pain was terrible), ILLNESS (she got horribly sick again for 24 hours) and HEADACHE (headache) had resolved and CERVICAL RADICULOPATHY (inflammation of cervical spine nerves dermatome affected (right shoulder, arm forehead and neck) aggravated), FEELING COLD (so cold that she wore clothes to bed), CHILLS (chills), FATIGUE (fatigue), NAUSEA (nausea) and INAPPROPRIATE SCHEDULE OF PRODUCT ADMINISTRATION (First 3 doses of Pfizer then received Moderna vaccine) outcome was unknown.        For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   Patient had terrible side effects after getting the 2nd booster dose of the Moderna Covid-19 vaccine. After she got the 2nd booster dose (Moderna) she got it because that was the only brand available at that time. She got horribly sick again for 24 hours (the terrible part lasted for 24 hours. She was able to get up from bed but she still had the symptoms). The most prominent symptom was horrible neck pain and head ache. She knew that this was caused by the inflammation of her cervical spine nerves  and she knew because of the dermatome that was affected - right shoulder, arm, forehead and neck. She already had this before but it got aggravated after she got her injection. She took Ibuprofen 400mg-600mg but did not give her relief. The pain was terrible that she wanted to get an appointment with her pain management provider but was not able to get one and it resolved on its own.  She also had chills without fever; she was so cold that she wore clothes to bed; she also had some fatigue and some nausea which was very similar to when she got the 2nd dose of Pfizer. Patient's daughter who was in the genetics field said that she could have a certain HLA type which could cause her to have the reaction to the Pfizer vaccine but now she was thinking this could also be the same reason why she was reacting the same way after getting the Moderna vaccine. She stated that it was something intrinsic that might have caused her to react this way. She had not had any Covid-19 diagnosis and no concomitant medical conditions.
