I can understand the system not being sophisticated enough to flag if two vax 'appointments' are made, that makes sense. I was more thinking about these so-far imaginary people who are booking lots of appointments to prevent others from receiving the vaccinations.. although I guess I was presuming those people would have already been vaccinated themselves, and that the online registry would have flagged it if someone had already received their vax under that same healthcard number.
I don't blame your son at all for keeping the two appointments until he was sure he was able to actually receive the first scheduled one, as there have been reports of people's appointments being suddenly cancelled without a new replacement appointment being issued (seems every time the govt changes its mind about who should get one first, they nab the doses and send them to where they deem they're more needed!). I don't see that type of thing as causing the problems Alberta's top public health doc was warning about.
If like JDG proposed, it is anti-vaxers who are booking all these bogus vax appointments, I guess it is possible they could be doing it using their own healthcard number, but never being flagged in the system since their healthcard number has not yet received an actual vax... but if that is what was happening, you'd think it would be simple for an insider to have a look in the database to see the number of appointments scheduled by duplicate healthcard numbers? Whole thing, once again, does NOT make sense.
I'm wondering too, if the whole thing got started after a misunderstanding in comprehension by one louder-mouthed person active on social media, who possibly misunderstood that people had entered themselves on numerous 'wait lists', as opposed to 'actual appointments'?? That is sure a possibility, with the mass confusion we have seen.. at least here in ON, the province would be saying 'anyone 40 and over are now eligible to book a vax appt starting on Monday', but meanwhile, when the people went to the site to register for an appointment, the local health department's rules would read that 'they are now accepting anyone over 70',... stuff like that was happening, and it seemed that each municipality had their own 'rules'. And of course, there WERE no actual appointments to register for, only 'wait lists' and apparently each vaccination site had its own waiting list.. so if people did qualify as per the local health department's rules, people were registering on MANY waiting lists... which could perhaps lead some lower-functioning person to assume that by doing so, other people were prevented from also 'registering'?? imo. Once again, hope they elaborate what that was all about.
