Prescribing Information can be found in the top right corner of the website. Information about adverse event reporting can be found towards the bottom of the page.
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product.
Healthcare professionals are asked to report any suspected adverse reactions via a Yellow card. Reporting forms and information can be found at https://coronavirus-yellowcard.mhra.gov.uk/ or search for MHRA Yellow Card in the Google Play or Apple App Store and include the batch/Lot number if available.
Alternatively, adverse events of concern in association with COMIRNATY can be reported to Pfizer Medical Information on 01304 616161 or via www.pfizersafetyreporting.com.
Please do not report the same adverse event(s) to both systems as all reports will be shared between Pfizer and MHRA (in an anonymised form) and dual reporting will create unnecessary duplicates.
COMIRNATY is a Prescription Only Medicine which has been centrally procured by the UK government.
