And 71% of cases occurred within 15 minutes of receiving the vaccine.

For the Moderna vaccine, the same system found 1

0 cases of anaphylaxis after a reporter received 4,041,396 doses of the vaccine – which is 2.5 cases per million doses given.

Nine of the 10 cases occurred within 15 minutes of receiving the vaccine.

Fortunately, no anaphylaxis-related deaths have been reported.
