Submit your medical enquiry on a Pfizer medicine. 

In the event of a suspected adverse event or side effect with no associated medical information enquiry, please report via www.pfizersafetyreporting.com/

*If you have a medical information enquiry including those with associated adverse events, contact Medical Information. 
Adverse events should be reported. Reporting forms and information can be found at https://yellowcard.mhra.gov.uk/ or search for MHRA Yellow Card in the Google Play or Apple App Store.

If you are concerned about an adverse event it should be reported on 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. When reporting please include the vaccine brand.


Alternatively, adverse events of concern in association with the COVID-19 mRNA vaccines 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.
