Using remaining opened vaccine in out reach clinic?

In Bhutan, opened vaccine in Out Reach Clinic (ORC) and leftover vaccines are discarded at the end of the session as we do not have the open vial policy. Only unopened vaccines are brought back and are used in the subsequent immunization session that are also maintained in proper cold chain. But what if we bring back the opened leftover liquid vaccine from the ORC and use it for the next session? What is Technet  group members' opinion/view on it?

Can vaccines be demaged due to x-rays?

Dear Forum,

We have continued having measles cases around the world despite the child’s immunization status. I have come across cases were a child was immunized but still gets the disease. I know most people will zero down to poor vaccine management practices, wrong immunization technique / practices and so on. However, we still have unanswered question, because some of the vaccines we use are live antigens and the question is will these vaccine get damaged if scanned using x-rays????...

SDD freezers that maintain -10C and below


I am brand new to TechNet-21 so this will be my first posting. 

I am trying to find an SDD (Solar Direct Drive) freezer which will maintain -10C and below. The product I need to store in Nigeria is surfactant (injected into the lungs of premature babies with collapsed lungs to give them life) which must be kept at that cold temperature to maintain a shelf life of 3 years. The electricity supply throughout the country in Nigeria is erratic and undependable, thus I would ...

Vaccine apps

There is a need for immunisation programmes to maintain high vaccine coverage, for which digital technology offers an opportunity. mHealth initiatives are largely in place already, and vaccine mobile applications are one of them. Vaccine apps that I am aware of provide the user with very useful information; however, this one-way type of information flow makes of the user’s experience a static one. Does anyone have experience with more dynamic vaccine apps or more tailored immunization experie...

Dear all technet Members

We are glad to share the Measles and Measles-Rubella (MR) Vaccine Five-dose vial presentations Facts sheet.

This Facts Sheet informs of the availability of Measles vaccine and combined Measles-Rubella (MR) vaccine in both a 10-dose vial and a 5-dose vial presentations through (or via) UNICEF procurement. The 5-dose vial presentation has the potential of reducing open vial wastage in some country settings compared to the 10-dose vial presentation.


Td vaccine in pregnancy

Dear TechNet members,

Bhutan is using Tetanus-Diphtheria (Td) during pregnancy. Guidelines provide clear instruction for women who have no record of previous Td vaccination and those who have received 3, 4 and 5 previous doses of Td containing vaccine. However, I could not find how many doses of Td should be given to pregnant women who has already received 1 or 2 doses of Td containing vaccine in the past.

Appreciate your expert advice please. 

Thank you.

How is the data from a 30 day temperature data logger used?

I was recently looking at a sample print out of a 30 day data logger. The high temperature alarm went off 4 times in a 30 day period. Having this information what does the health worker typically do with the vaccines? Some possibilities are: - Throw away the vaccines. - Ignore the alarms and use the vaccines as if the alarms did not go off. - Issue a notice that the vaccines should be used within a certain period of time. What determines that period? If someone has field experience please let m...
