Anyway I don't want anything to do with this or any other make of the vaccine until it's been thoroughly tried and tested - and by that I mean on the population in general and not just a few thousand 'guinea pigs', especially as I know from googling it online (The Wellcome Trust) that it usually takes an average of 10 years from initial research, through phase trials, to final authorisation by the appropriate health bodies before any new vaccine an be administered - yet the Covid vaccines are being made available after only a few months.
I could be wrong, but my understanding from a piece with an expert on Radio 4 a few weeks ago was that this vaccine has not had to be created from scratch. Covid-19 apparently has many similarities with SARS which a vaccine was developed for around 15 years ago. So it only took a bit of tinkering (which they'd already got) last February 2020 to get the vaccine adapted.
This is, I gather, why we can get a 'new' flu vaccine every year - i.e. they don't have to start from scratch.
I'll be getting it as soon as I'm offered (which is probably months...)
