Reporting an adverse event for the Covid-19 mRNA vaccines

Reporting an adverse event for the Covid-19 mRNA vaccines 

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 and batch/Lot number if available.

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 anonymized form) and dual reporting will create unnecessary duplicates.
