might have what looked like bells palsy on one side of his face; second dose appointment was scheduled for 15May2021 which he missed; neurologic spasm up and down his spine; serious rigid back in the middle of his back; swollen lymph nodes along his neck/ has swollen lymph nodes; vomiting; This spontaneous case was reported by an other health care professional and describes the occurrence of BELL'S PALSY (might have what looked like bells palsy on one side of his face) in a 28-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.     No Medical History information was reported.    In April 2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 17-May-2021, the patient experienced VOMITING (vomiting). On an unknown date, the patient experienced BELL'S PALSY (might have what looked like bells palsy on one side of his face) (seriousness criterion medically significant), PRODUCT DOSE OMISSION ISSUE (second dose appointment was scheduled for 15May2021 which he missed), NERVOUS SYSTEM DISORDER (neurologic spasm up and down his spine), MUSCLE RIGIDITY (serious rigid back in the middle of his back) and LYMPHADENOPATHY (swollen lymph nodes along his neck/ has swollen lymph nodes). The patient was treated with CANNABIS at an unspecified dose and frequency. At the time of the report, BELL'S PALSY (might have what looked like bells palsy on one side of his face), PRODUCT DOSE OMISSION ISSUE (second dose appointment was scheduled for 15May2021 which he missed), NERVOUS SYSTEM DISORDER (neurologic spasm up and down his spine), MUSCLE RIGIDITY (serious rigid back in the middle of his back) and LYMPHADENOPATHY (swollen lymph nodes along his neck/ has swollen lymph nodes) outcome was unknown and VOMITING (vomiting) had not resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 05-May-2021, Olfactory test: negative (normal) negative but it was 24 hour test.     The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown) was unknown.   For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications reported. Treatment medication not reported.  This case concerns a 28-year-old male patient who received first dose of mRNA-1273 and missed second dose (missed dose.  The patient experienced additional events after first dose for which based on the current available information and temporal association between the use of the product and the start date of the events, a causal relationship cannot be excluded. vomiting is consistent with known safety profile of the vaccine.  However, patient was on multiple concomitant medications which confounds the reported events.; Sender's Comments: This case concerns a 28-year-old male patient who received first dose of mRNA-1273 and missed second dose (missed dose.
