Better if the olds go first. Don’t want to take away their vaccines.
Young, healthy people getting vaxxed now are selfish.
Only if you don't live in the US, UK, or Israel. I'm sure there other countries that have thoroughly vaccinated their olds too, but I don't know them off-hand.
Yes, but even in the UK there are basically no healthy people in their 20s or 30s who have been vaccinated, although we’ve vaccinated a higher percentage of our population than the US. Compared to the US, we’ve prioritised getting it too as many old and clinically vulnerable people as possible first.
