I've asked (in general) before - exactly what do people want in a 'vaccination target or plan'? The message I hear is "everyone who can, get vaccinated as soon as you can, with the vaccine appropriate for you (+/- dr advice)." Sounds like a target/plan to me.
"Targets" - that old chestnut, a mechanism to get something on paper that can only fail. Absent pinning people down and forcing a needle in, government can't force a certain % to get vaccinated. So if they set a target for certain things to then happen, and it isn't met because the punters won't get the needle, what happens then? The target/plan fails.
Side effects of Pfizer are out there. What happens if Pfizer hesitancy emerges OR its declared not suitable for certain groups. Again, target/plan fails.
What happens if a new strain emerges, resistant or more resistant to all the present vaccines, so its pointless to get it - hesitancy becomes 'stop'. Would you expect the government to ahhere to a plan/target set now?
The target I hear "everyone who can, get vaccinated". Seems clear to me.
PS a more pertient question might be "What's the target date for ending lockdown in xx_ state?". And the answer is equally elusive, for the same basic reasons - things unknown and unknowable at the moment.
