Feel free to explain or link me to your explanation. But regardless I have difficulty trusting what any pharmaceutical company, or government controlled by pharmaceutical interests says, because I know people who have been killed by them and more who have had their lives ruined by them.
This isn’t because I have preconceived political beliefs. I’m not a conservative. But I’m also not a Democratic partisan and I don’t trust any corporation that has deliberately killed people when liberals tell me to either.
If these vaccines are safe, good. But I’m not going to be first in line to to get them.
It's a bit hard to track down what I wrote previously, but as I understand it they did two big things that are not usual when commercial vaccines are developed.
One was that government, at least in some countries such as the UK, promised from almost the start of the development, to buy large quantities of each vaccine, whether they worked or not. That meant that the manufacturers could invest in production of the vaccines while the clinical trials were still in progress. In the normal course of events they would obviously have to wait for trials to finish successfully and then wait for regulatory approval, before they would spend money on producing them.
The other thing they did was that the regulatory agencies, at least in the UK, did something they never normally do. This was to review the chunks of trial data as they came in, instead of waiting for the whole data set to be completed and then letting it take its place in the queue to be reviewed
en bloc.
These measures cut several years out of the "normal" development cycle, without compromising in any way the technical standards that had to be met for approval.
