The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) was unknown.       Treatment information was not provided.  Company Comment: Based on the current available information, the mRNA-1723 does not contain a virus capable of causing infection and with the occurrence of COVID-19 infection after vaccination, this event is assessed as unlikely related to mRNA-1273. Based on the current available information and temporal association between the use of the product and the start date of the rest of the events, a causal relationship cannot be excluded.; Sender's Comments: Based on the current available information, the mRNA-1723 does not contain a virus capable of causing infection and with the occurrence of COVID-19 infection after vaccination, this event is assessed as unlikely related to mRNA-1273.
