Reporting side effects

Include the vaccine brand and batch/lot number in Yellow Card reports if available.

Reporting potential defects

In accordance with the published information and existing guidance, any potential defects identified by healthcare professionals should be managed as set out below (modified September 2021 to reflect current practices).

  1. Do not use the vial for vaccination.
  2. Do not discard the vial, instead please keep it aside in a secure place as further investigation may be required.
  3. Complete a Yellow Card or contact the MHRA Defective Medicines Report Centre directly (DMRC@mhra.gov.uk).
  4. Once the report has been logged via the Yellow Card system, the complaint will be assigned a UNIQUE MDR# number (please note a new MDR# number is generated for each complaint so please retain for your records).
  5. Samples should not be sent without being reported through the Yellow Card system and must have attached the description of complaint/Yellow Cards and reference numbers. Any unidentifiable samples will be destroyed.
  6. In the usual way, report the issue to the National Vaccination Operations Centre (NVOC) via the agreed escalation process, including batch number and any other relevant details.
