I asked at third and fourth vax, where was the other option that had been my only option* for the first two (I also had my paperwork) on both occasions I was informed that it had been withdrawn. My 'why?' was met with 'don't know'.
I understand the tightrope of not wanting to admit the threat from blood clots was significantly higher than had been admitted, and that to climb down over promises of safety undermined the vax program from there, but to ignore that part of the roll out and the associated untruths crushes any faith in anything they said. If that type of vax then wasn't deemed safe anymore, all recipients ought to have been written to to explain why and update the long term health possibilities that were undercut from the initial announcement.
Quite simply, is there a brain blood clot timebomb waiting out their in society? Will it manifest as an epidemic of sudden strokes? What's the timeline on any expectant risk of harm? Are measures and specialists in place if a sudden mass of brain damaged patients arrive en masse?
This lack of information and perceived lack of planning could be used by the unscrupulous to whip up a panic...
If you’re talking about the AstraZeneca one, yeah it was withdrawn, in part because it had the associated blood clot link which the other vaccines didn’t.
My understanding is that is was still massively low frequency, but if there’s a vaccine that doesn’t have that specific risk, then sensible to prefer that one.
Thing to remember is that vaccine trials were massive - tens of thousands of people - absolutely huge for a vaccine. But even so, if there’s a side effect that’s 1 in 100,000, then it’s likely that the trial won’t pick that up, as it’s too low frequency to be spotted.
In terms of long term risk, its obviously impossible to say until time passes, but as far as I know vaccine side effects happen in the first month, and tend to be a reaction to the body’s immune response. The blood clot, myocarditis are all a side effect of a persons specific immune response.
In fact for all the talk of myocarditis, it’s a well known vaccine side effect in other vaccines, most notably smallpox, but again is low frequency enough to be an acceptable trade off, as well as the fact that myocarditis and blood clots happened in response to the virus itself (at higher rates, I think), specifically because those side effects are down to the body’s immune response.
People want black and white answers. “It’s 100% safe, it’s 100% effective” or “it’s useless, it’s lethal” and are less persuaded by boring conversations about balance of risk and acceptable trade offs.
