On 31-Mar-2021 at 11:00 AM, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to .5 dosage form. On an unknown date, the patient received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) .25 dosage form. On 05-Mar-2021,  after starting mRNA-1273 (Moderna COVID-19 Vaccine), the patient experienced NEUROPATHY PERIPHERAL (Increased Neuropathy,after each vaccine my Neuropathy got much Worse, burning and stinging in my feet got increasing) (seriousness criterion medically significant). The patient was treated with INSULIN for Diabetes mellitus, at a dose of 1 dosage form.

Company comment: This spontaneous case concerns a 68-year-old, male patient with relevant medical history of neuropathy due to Type 2 Diabetes Mellitus (T2DM) and Lyme disease, who experienced the unexpected, serious (medically significant) event of peripheral neuropathy. The patient experienced worsening neuropathy, described as 'numbness, stinging and burning' 2 days after receiving the first dose of mRNA 1273 COVID-19 vaccine. The patient was treated with insulin which helped with the neuropathy. The patient again had worsening of neuropathy after he received second dose (28 days after first dose) and third dose (6 months after). The re-challenge is positive, since patient experiences peripheral neuropathy after every vaccine. The medical history of neuropathy due to T2DM and Lyme disease, remain as confounders. The benefit-risk relationship of the mRNA-1273 vaccine is not affected by this report.
