For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   In Dec-2022, the patient husband got infected and ended up infecting the rest of my family. All the family was vaccinated and boosted. The patient and her husband were sick. The family was boosted around the same time, but received half dose for the booster, and nobody got seriously ill and sick. The patient took Paxlovid, the patient was recovered, and it was interesting because when my husband was trying to determine what the appropriate booster was, totally five of us were infected and vaccination records are not available at the time of the call.  All family members received the same number of doses of COVID-19 vaccine except for the caller who works as a HCP.  Patient received 5 or 6 doses of the Moderna COVID19 vaccine.  No concomitant and treatment medications were reported.   This case was linked to US-MODERNATX, INC.-MOD-2023-745748 (Linked Report).
