JAMA Oncology found people who received a second dose of Moderna's COVID-19 vaccine were more likely to show abnormal lymph node radiotracer uptake on FDG-PET scans that can mimic malignant cancer, than those vaccinated with the Pfizer shot. The findings, based on FDG-PET/CT scans of 1,290 patients at Yale New Haven Hospital, suggests "Ipsilateral axillary nodal reactivity is commonly seen after the intramuscular administration of the COVID-19 mRNA vaccines, more so after the second dose than after the first, and more commonly with the Moderna than the Pfizer vaccine," clinical fellow Dr. Mehmet Adin wrote."/> JAMA Oncology found people who received a second dose of Moderna's COVID-19 vaccine were more likely to show abnormal lymph node radiotracer uptake on FDG-PET scans that can mimic malignant cancer, than those vaccinated with the Pfizer shot.

A study in JAMA Oncology found people who received a second dose of Moderna's COVID-19 vaccine were more likely to show abnormal lymph node radiotracer uptake on FDG-PET scans that can mimic malignant cancer, than those vaccinated with the Pfizer shot. The findings, based on FDG-PET/CT scans of 1,290 patients at Yale New Haven Hospital, suggests "Ipsilateral axillary nodal reactivity is commonly seen after the intramuscular administration of the COVID-19 mRNA vaccines, more so after the second dose than after the first, and more commonly with the Moderna than the Pfizer vaccine," clinical fellow Dr. Mehmet Adin wrote.
