Suspected adverse reactions associated with COVID-19 vaccines should be reported to the MHRA through the MHRA’s Coronavirus Yellow Card reporting site or via the Yellow Card app.
As these products are under additional monitoring, this includes all suspected adverse reactions associated with these vaccines. This will allow quick identification of new safety information.
When reporting please provide as much information as possible, including information about medical history, any concomitant medications, onset, treatment dates, and vaccine product brand name and batch number.
You may be contacted following submission of a Yellow Card report so that we can gather additional relevant information for the assessment of the report. These contributions form an important part of our understanding of suspected adverse events.
