Ok let's look at what you've said here Teacake44. I'll not address the issues you've raised in your 20:19 post as they reflect your own personal feelings of what's going on. You may be right but others might disagree.
Now let's look at your 20:57 post. Stock samples of all vaccines are kept in laboratories for research purposes. SarsCoV19 is a vicious pathogen that has mutated many times. We believe that there are hundreds of variants in existence and the vaccines have to be tested on variants that arise in in any particular region. It's ongoing and just like the flu vaccine, Covid vaccines will need to be tweaked regularly. The Moderna vaccine's effectiveness against worldwide variants is being assessed constantly.
Your third sentence onwards discusses your views about the Pfizer vaccine. No one knows the level of protection it gives against new variants as yet. Annual flu vaccination gives theoretical 40% to about 70% protection against flu yet it's provided every year but can't be called 100% effective. The Pfizer vaccine is 95% effective after two doses. So let me ask you this: define effectiveness for me. What would you regard as an effective vaccine? Would it be the 40% or so of the flu or the 95% of the Pfizer. Is some protection better than none? Would you decline the vaccine because it may not meet your criteria for an "effective" vaccine?
The Pfizer vaccine is considered to be effective against the current variants in the UK. You cannot conclude that because we are not 100% certain about the effectiveness of the Pfizer vaccine against new variants that you are being asked to take a vaccine that offers no known protection against the new variant. Our uncertainty does not mean that you can conclude it offers no known protection.
By now you will be aware that most viruses mutate constantly and produce variants. Vaccines are developed to try to overcome this feature of their behaviour, which means either new vaccines or tweaked vaccines will be needed. All will have different effectiveness figures. Don't get to bogged down with these figures. Just be thankful that they will provide protection no matter whether you are offered the Pfizer, AstraZeneca, Moderna or other vaccines now or in the future.
I don't bang my drum very often here on AB but I can tell you that I've spent a fair bit of my time over the last year in laboratories with dedicated expert teams working around the clock in order to overcome this virus. The research has played a part in the development of the vaccines currently available. Don't let issues about effectiveness cloud you judgement over having the vaccines.
