EMA issues advice for users of live PRRS vaccines
The VMD has been made aware of an incident in Denmark involving an outbreak or PRRS.
The European Medicines Agency (EMA) has produced some advice for users of live Porcine Reproductive and Respiratory Syndrome (PRRS) vaccines following an ‘incident’ in Denmark.
The Veterinary Medicines Directorate (VMD) said in a statement that it ‘has been made aware of an incident in Denmark involving an outbreak of PRRS.
‘This outbreak has been caused by an emergent recombinant strain of PRRS virus which is believed to have resulted from the recombination of vaccine strains from two live PRRS vaccines which had both been used on the farm.’
The statement continued: ‘Further investigation is ongoing. Whilst waiting for further information the European Medicines Agency (EMA) has produced some advice for all users of live PRRS vaccines. The advice is contained in the last item in the EMA’s press release.’
The VMD is reminding users to report any cases of adverse reactions or suspected lack of efficacy involving these vaccines to the relevant marketing authorisation holder or direct to the VMD via its online reporting form.
The Veterinary Medicines Directorate (VMD) is inviting applications from veterinary students to attend a one-week extramural studies (EMS) placement in July 2026.
