I must admit, with all these apparently effective vaccines now coming online, I'm starting to get confused about which one is which, their efficacy, and what they're supposed to be particularly good at combating. How are we going to keep track of side-effects, effects and so on with half-a-dozen vaccines doing the rounds? Will people actually know which vaccine they've received, so they can report back on it? And how will we be sure, if someone assures you that "I've had the vaccine", whether they are unable to transmit it/be severely adversely affected/require hospitalisation etc.? Will we end up being given "specialist" vaccines tailored to our medical history, age, ethnic background etc.? I think I shall need a nice clear comparison table, if anyone knows of one ...
