In Oz, because the rate of infections is very low here the people-in-charge-of-the-country have decided to wait until the clinical trials are completed before starting vaccinations. Enough doses of the vaccines (two brands at least) have been secured so the whole country will be vaccinated - or at least, the people who don't rely on farcebook for their opinions, I guess.
Go science! Go medical expertise! Yay! (that's my opinion, so I'll be standing in line for the vaccinations when they are available, and being an old f@rt, I'll be in one of the earlier prioritised groups.)
