Adverse Events Reporting

Sanofi Pasteur MSD continuously evaluates and monitors the ongoing safety profile of our products in accordance with global regulatory requirements. The safety of our products is paramount and our pharmacovigilance system ensures all adverse events are collected, monitored and analysed to allow identification of any possible changes in the safety profile of our vaccines.

Most patients are vaccinated without suffering any unwanted effects although there are some who may experience an adverse event.  An adverse event experienced after vaccination may not necessarily be caused by a vaccine; it may just be a coincidence. 

If you are a patient or a non-health care professional and are concerned about a possible adverse event or require medical advice you should contact your doctor. 

If you would like to report a possible adverse event to Sanofi Pasteur MSD UK using the SPMSD UK internet site, please complete our online Adverse Event Reporting Form . Alternatively you can report an adverse event to the pharmacovigilance department of SPMSD by telephoning 01628 785291. 

SPMSD UK will endeavour to acknowledge receipt of your online adverse event reporting form to the email address you have provided by the following working day. If however, you do not receive an email acknowledgement within 2 working days after submitting this form, please call 01628 785291.

To assist us in evaluating the safety of our vaccines we may need to obtain further details, if this is the case we will request that you complete a follow up form which will be provided with a pre paid envelope to the postal address you have supplied.   If you are a patient we may ask your permission to follow up with your doctor in order to obtain further information about your adverse event.

Thank you for your collaboration.
