@coronahope we were given our IOM vaccination forms and told to do the same vaccinations again after 4-6weeks. It's more like the immunization sequence followed for infants. It ensures the vaccination process is complete which is then indicated on vaccination certificates. Right now our vaccination forms show 'incomplete'.
The IOM nurse explained that if we don't complete those vaccines here we'll have to do it in the US which will pose other complications and it's expensive. We have children and were told without the proper vaccinations for them it will difficult to enroll them in school. The only glitch is one has to pay for the vaccines again, around 20k @IOM but cheaper at City hall which is certified to do such shots.
It's vital to preview the IOM vaccination forms after the medical test to confirm your names, birth dates, passport# are written correctly. Ours had errors so we returned them and were corrected. It's this info that will be printed on the medical certificates that will be issued at the embassy. It's safer to ask questions before leaving IOM to not miss anything.
