If they are so certain that the vaccine is safe, why were there so many instances of denying a debate in the House?
I'm not clear when you allege this happened. There have been at least five debates in Westminster Hall triggered by e-petitions, many other parliamentary debates, many questions and much committee work.
Why was the House so poorly attended when AB was finally allowed to speak?
Adjournment debates are generally poorly attended.
Given that huge numbers worldwide had this new fast tracked vaccine, without the usual testing process, why wouldn’t discussions about how it panned out be permitted?
This is, of course, misinformation, The vaccines went through the usual testing process in full. No steps were skipped. They went through exactly the same layers of review and testing as any other vaccine.
So how were they able to get it done faster than normal?
Firstly, funding. It costs a lot of money to create a vaccine. This leads to hesitancy in funding vaccine development efforts. However, in this case governments and others were providing huge sums of money to take away the cost constraints.
Secondly, companies normally wait until a vaccine is approved before starting manufacture. In this case, funding was available to allow them to create millions of doses prior to approval. Of course, these doses were not distributed until they were approved.
Thirdly, the clinical trials. There are three phases to clinical trials. Normally, companies wait until a phase is complete before they start planning the next phase. This can result in a one- or two-year gap between phases. These gaps were eliminated so that the phases could run back-to-back. However, each phase ran for the normal length of time and was completed as usual.
There are other factors but those are the main ones. But the important point is that the vaccine went through the usual testing process in full.
The problem is that there are a lot of people, including Bridgen, who peddle disinformation. To say so isn't "shutting down discussion". No-one has a problem with a discussion using actual facts and genuine statistics. However, a sensible discussion based on made up facts and statistics is not possible.
