Company comment: Based on the information provided which indicates patient's underlying history of nephrostomy, a causal association between the event of nephrostomy bleeding and dehydration and the administration of mRNA-1273 and the events is assessed as unlikely as  the event is common local complication from nephrostomy tube placement,  The other events are temporarily associated with the product use and a causal relationship cannot be excluded.; Sender's Comments: Based on the information provided which indicates patient's underlying history of nephrostomy, a causal association between the event of nephrostomy bleeding and dehydration and the administration of mRNA-1273 and the events is assessed as unlikely as  the event is common local complication from nephrostomy tube placement,  The other events are temporarily associated with the product use and a causal relationship cannot be excluded.
