The patient's weight was 240 pounds, and height was 162.56 centimeters. The patient's pre-existing medical conditions included: The patient had no other conditions. The patient received covid-19 vaccine ad26.cov2.s (dose number in series 1) (suspension for injection, route of admin, and batch number were not reported) dose was not reported, 1 total, administered to right arm on MAR-2021 for covid-19 prophylaxis. Age at time of vaccination 5 decade old. The batch number was not reported and has been requested. No concomitant medications were reported.

On an unspecified date in NOV-2021 (02-NOV-2021 or 03-NOV-2021), within a day or 2 (24-36 hours) the patient developed a very large lymph node on left collarbone (dose number in series 2). On an unspecified date, the patient developed symptoms of fever (dose number in series 2) and not feeling well again. After a few days the patient started to notice lumps/nodules in left bicep which started with 1 lump (dose number in series 2), called the doctor and doctor suggested collarbone lymph node was a sign the patient developed good immunity. Doctor said the lumps in arm were probably the same thing and that basically should maybe last a couple of weeks and then would go away. After a few weeks the lymph node in collarbone went down a little bit, maybe halfway, but the left arm lumps did not, lumps continued to get bigger. The patient visited the doctor and did an ultrasound of upper left arm and collarbone area on 03-DEC-2021 found lymph node measured in collarbone. The one in the arm doctor could feel but was not able to be picked up on ultrasound. It was reported as unable to visualize a definite area, palpable abnormality. The large lymph node on left collarbone had gone but there were 3 lumps in upper left arm. It was mentioned there was an upcoming appointment is 02-FEB-2023, goes in every couple of months to check lumps which are there, does another ultrasound to keep up with it, this will be patients 3rd ultrasound coming up. The action taken with covid-19 vaccine ad26.cov2.s, and tozinameran was not applicable. The patient recovered from very large lymph node on left collarbone, had not recovered from lumps/nodules in left bicep and upper left arm, and the outcome of fever, not feeling well/felt little crappy and revaccination with different covid-19 vaccine was not reported. This report was non-serious.
