Thank you for taking the time to review our ideas. You are correct that there would be concerns in a number of areas, but the key has to be ability to achieve a high number of people being vaccinated with a minimal supervision. It is our opinion that the only service that makes sense when you scale is self-service. Even automation requires unrealistic amounts of equipment that cannot be transported to remote locations. We believe that all processes are iterative and you learn from smaller groups until you have the volume to justify your confidence in large scale rollout. The key is always refinement of the process, foolproof procedures and minimising the contact points with the equipment you are using. Given that self service is cheap, you can even send out an equal number of saline type doses in advance and then have people run them and test the success rate on the results, that can be measured locally. What our system does have is that it does not look intimidating, it captures biometric information of the caregiver and the recipient (who should be the same in most cases) and it provides a wealth of information in the identification of both people and through the bloods possible localised health issues. Given that we had only an hour to submit our idea before the original deadline the quality of our drawing leaves a lot of be desired, but we feel that if nothing more it may inspire more discussion as we are ideas people. Like any service, we believe that this idea needs to find the immunisations that would suit it's format, but from what we can see no one has currently come up with the key ingredients of 1) High tech management 2) robust and unthreatening low tech delivery 3) biometric capture and 4) large scale self service.
