POST 01117E : VVM ANNIVERSARY Follow-up on Posts 01101E and 01106E 5 July 2007 _____________________________________ Ümit Kartoglu from WHO/HQ replies to [log in to unmask]">Robert [log in to unmask]">Steinglass _____________________________________ Dear Robert, Thank you for your kind words for the 10-year anniversary's VVM global event. I also thank you for raising these concerns regarding the policy statement. In freeze-dried presentations, VVMs are placed either on the top of the vial or on the neck of the ampoule. VVM can ONLY be referred to until the time of reconstitution. With reconstitution, the section where the VVM is on is removed (you have to break the flip-off, or break the neck and then throw away these parts). After reconstitution the vial must be kept cold and cannot be used beyond six hours. Since there is no visible VVM on the vial, naturally, VVMs cannot be referred to. This section in the joint policy statement describing "special circumstances" is taken from the "Getting started with vaccine vial monitors ( WHO/V& B /02.35)" manual page 9. This means, these were WHO recommendations since 2002, now they are also spelled out in a policy document. The very beginning of the policy statement also refers to the same document. In the technical document "Getting started with vaccine vial monitors ( WHO/V& B /02.35)", after listing these circumstances, the following note is given: "Remember that freeze-dried vaccines (measles, BCG, yellow fever, and freeze-dried formulations of Hib) should not be transported to their point of use if the availability of ice cannot be guaranteed. Ice is necessary in order to keep the vaccines cool after they have been reconstituted." I am sure we all appreciate the difference between "policy statements" and "technical documents/guidelines" explaining "how to". With warm regards, Dr Umit Kartoglu ______________________________________________________________________________ All members of the TechNet21 e-Forum are invited to send comments on any posting or to use the forum to raise a new discussion or request technical information in relation to immunization services.
