For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter did not provide any causality assessments.   Immediately following administration of the first dose of the Moderna Covid-19 vaccine on January 22, 2021, the patient experienced no signifiant symptoms - only minimal soreness and redness at the injection site which abated within 24 hours. One week later, at between 8:45 am and 9:00 am on the morning of January 29th , the patient experienced the first symptoms: intense itching, a circle of redness and induration/swelling that was "sore"/painful to touch around the vaccination site on my left arm. The red swollen area increased in size and by the end of the day encircled my upper arm. The itching, redness and swelling gradually diminished and by January 31st there was just a pale red area around the vaccination site which disappeared in a few more days. By about 10 am on the morning of January 29th I experienced other symptoms - I suddenly felt so weak as if I was about to faint and lay down to avoid falling. The patient remained lying there for about an hour when I felt my strength had returned. Within that hour I experienced intense nausea which abated by the time I felt strong enough/back to normal and resumed my normal activities as if nothing had happened. I had no other symptoms after that. I self administered benedryl topical ointment to the red itching area, but did not not seek medical attention at the time. The patient had a video appointent a few days laterwith my internist to describe what had happened. The patient was concerned whether the patient might have a more adverse reaction with the 2nd vaccine administration. She consulted with others and told me to go ahead with the 2nd vaccination. She prescribed EpiPen for me to have ready after my second vaccinatio appointment and advised that the patient wait longer than the prescribed 15 minutes, but the second Covid 19 vaccination was uneventful.
