Pfizers strategy, and this is public knowledge, is to combine the flu shot with the vaccine using mRNA protocol so it becomes an annual/bi annual shot.
I have an issue with this in that we really don't know where Covid is going, it might disappear or it might morph into something that can't be " mRNA 'd" and old fashioned vaccines continue to do what they do extremely well.
Also we really don't know anything how or what mRNA does or doesn't do to the immune system, long term.
Don't get me wrong its fantastic technology and might cure cancer, diabetes, dementia.......and of course it has given the " western world " the route back to " normality ".
Just my thoughts, the vaccines work but sometimes it's good to scrutinise a bit more.
I should add my parents can't wait 82, 78 .
