I've seen several people ask if there's any surveillance of the number of people who develop COVID after they've had part 1 or 2 of their vaccination. There is a surveillance scheme to which it should be reported:
The following cases should be reported:
Individuals with a SARS-CoV-2 PCR positive sample with symptom onset date at least 10 days after their first dose of vaccine (this includes any cases who develop symptoms after a second dose of vaccine).
If the case was asymptomatic, test date should be used in place of symptom onset date.
Vaccinated individuals who test positive using a lateral flow device should be confirmed using PCR.
