I prefer to give more credit to the people who created the vaccine, Oxford and BioNTech over the pharma companies who will mass produce it.
This is not how the Pfizer vaccine works.The problem with these sort of treatments is they often attempt to kill the virus but end up killing everything else too resulting in side effects. Another problem is unless you can guarantee killing every single viral particle (impossible) then it's pointless because the key to all viruses is they can replicate within a host.
In effect a viral infection is a bucket filling with water (viral load) but as the bucket fills the rate at which it fills increases (replication). The only limiter on stopping the bucket filling is the bodies immune system but immune systems have never seen this virus before and so infections occur very easily and they hit people hard.
The Pfizer vaccine modifies the RNA of cells to make cell entry/replication more difficult by giving instructions on the protein spike of the virus. Less replication equals less viral load and the immune system deals with the rest meaning upon encountering the virus people are infected but the virus doesn't make them sick or infectious. The same thing happens with HIV treatments which target replication (and prevent eventual AIDS later down the line).
COVID-19 isn't dangerous to the vast majority of people but attacking infectivity is key in order to stop the spread to vulnerable people. Most healthy people below 60 have no need for a vaccine but they will need a vaccine if only to protect everyone else around them.
Yes I read this article this morning. A very interesting read.This is worth 10/15 mins of your time. It explains how the vaccine has been arrived at so fast, but in fact they've been preparing for this "disease X" moment for a decade.
It's also eye-opening that the usual "years to deploy a vaccine" is down to bureaucracy, filling in forms and twiddling your thumbs.

Oxford vaccine: How did they make it so quickly?
Good fortune and scientific brilliance were behind the Covid-19 vaccine being developed so quickly.www.bbc.com
That’s because lots of people on this thread know more than the scientists!Strange that some seem to want to downplay the effectiveness of the vaccine developed here and that we have most access to.
But it’s not ‘time’ as such that’s going to prove it. It’s other people going first. So those that’s say ‘I’m going to wait and see’ are really saying ‘I’ll let someone else take the risk’. And if we all say that, then what?
100 million.Can you recall how many doses of this vaccine the government ordered?
