Single Mumps Vaccine ... after Merck pulled out

4 replies

Need to be aware that many private clinics are trying to get approval for a new vaccine following the Merck withdrawal in 2011. There are none approved at the moment and at least one is following a similar route to a previously rejected vaccine under a new name .... it is important that vaccines are proven to be both safe and effective not simply safe.

The MHRA (the body which ultimately manages these approvals in the UK) last week posted its findings on statements made on the CIC website ..

Advertising investigations

13 September 2012
The MHRA was made aware of information presented on the Children?s Immunisation Centre (CIC) website about Medi-Mumps and a related press release. The MHRA was concerned that the information provided an unbalanced view of the safety and efficacy of the vaccine because it did not mention the MHRA?s concerns and previous CSM advice or that the product was unlicensed.

We understood that the Medi-Mumps vaccine is manufactured from the same stock and processed in the same way as Pavivac mumps vaccine. The MHRA, acting on advice from an independent advisory committee, the Committee on Safety of Medicines (CSM), has for a number of years objected to the importation of the Pavivac product because there is insufficient information available to assure its safety, quality and efficacy. See statement from the committee on safety of medicines (82Kb) for more details.

CIC amended the websites to remove the information about Medi-Mumps.

We, like many parents, have completed all our vaccinations except the mumps in both our children. We would consider the MMR however we have asked our GP and a Consultant to confirm that it is known to be safe to double/triple dose on the elements of MMR already received, and neither can say. We have written to Merck and received a reply passing us to another part of the empire and we are still waiting. We have written to our MP.

The NHS Choices website states it is ok but not the basis for this claim. A qualified PHd student in this field informally advised us that it should be ok because the body will ignore the known elements of the MMR.

We will pursue an answer from Merck but feel the government should do more to help clarify the position and reassure parents 'stranded' by the unplanned change in Merck's production policy in 2011 (which had initially lulled parents into a false sense of security calling it a temporary suspension in 2009). This is not the government' 'fault' but a duty of care to support families in this position should be a priority as it will in due course undermine herd immunity.

Well, to be honest, I think this should have been the duty of care of those doctors who chose to offer singles. Essentially, they should have ensured to have a complete set of M, M and R for each child who they started on a monovalent vaccine.

I am sorry that you are stuck with 2xMR, but your doctor didn't advise you correctly.

Completely agree catherina. The govt may help but its duty of care ended when those families (and doctors) chose to ignore its advice.

CatherinaJTV · 16/09/2012 18:47

And they are pretty much doing their duty if they control vaccines being imported for whether they are ok or dodgy.
I really feel for the parents/kids who are stuck though, since they fell prey to ill prepared (private) doctors...

Right but there's no 'we made a mistake, you were right, we messed up, our kids are now at risk, can you please help us out even though we ignored your advice?'. I'd have a lot more sympathy for that approach!
