1. PROVISION OF A-D RECONSTITUTION SYRINGES: DESIGN & AVAILABILITY ISSES
John Lloyd, PATH/CVP writes "One technical issue which emerged from the last
Fund review is that the Fund should, in addition to providing AD syringes,
also provide reconstitution syringes for freeze dried vaccines at the rate
of one per vial of vaccine, including reserve stock (buffer)."
" But the review group recommended auto-disable reconstitution syringes
which cannot be used for human injections. This would remain consistent with
the policy behind the provision of a-d syringes for injections."
* "We are urgently seeking sources for these products and will send you what
we have found as soon as we can."
* Robert Steinglass, BASICS II, suggests that the AD Reconstitution Syringe
should incorporate a fixed non-removable needle to prevent needle reuse.
* Robert also suggested that these issues be put to the Technet Forum.
AD is Auto-Disable, for a one use, self disabling device

Subject: Provision of A-D reconstitution syringes by the GAVI Fund
One technical issue which emerged from the last Fund review is that the Fund
should, in addition to providing AD syringes, also provide reconstitution
syringes for freeze dried vaccines at the rate of one per vial of vaccine,
including reserve stock (buffer). This means one per two doses of
pentavalent vaccine and one per ten doses of yellow fever.
The provision of reconstitution syringes by the Fund is generally covered by
the current guidelines and therefore there has been no additional
recommendation to the board. But the review group recommended auto-disable
reconstitution syringes which cannot be used for human injections. This
would remain consistent with the policy behind the provision of a-d syringes
for injections.
The product which is inferred by this recommendation is either:
- an A-D syringe of 1ml capacity (for pentavalent vaccine 2-dose) and an A-D
syringe of 5ml capacity (for yellow fever vaccine 10-dose) plus a large
diameter removable needle for reconstitution or
- a disposable syringe (1ml and 5ml) with a fixed large diameter needle for
reconstitutiion, which cannot be used for human injection.
We are urgently seeking sources for these products and will send you what we
have found as soon as we can.
All the best,
John Lloyd,
Resident Adviser PATH-CVP France.

Why would you want the needle to be removable on the AD option for
reconstituting?
Also, you and I discussed the disadvantage of having a needle which can
otherwise be used for injecting in the 1 ML AD syringe, as the syringe could
be used to immunize two kids.
I am thinking the non-AD syringe with fixed needle unsuitable for injections
is the preferred option. Maybe this is a question for TECHNET opinion,
too??
