Well, I didn't actually, it was EmilyChambers. I, too, commented on her hypothetical scenario.You are the one who brought up charging, I just commented on your hypothetical scenario.
yes the different brands may be slightly different but generally speaking if someone gets 3 covid vaccines they’re all the same they aren’t tweaked for different variants of covid, they are the same vaccine whereas the flu vaccines are tweaked each time for combating different strains of flu.
But yes, it's possible to have all three jabs the same, as each one stimulates your immune system to protect itself against the virus.
I understand they're doing research and trials into future covid vaccines being used against different strains which would make sense. I think someone who posted here has been part of trials, hopefully they'll clarify.
