Good thing I didn’t wait for my text message. My slot to book my second shot opened at 6pm and closed at 12pm the next day. Fortunately @afterspivak posted it in the info thread:
I saw it at 4am and was able to immediately book an appointment for my second choice of dates. I woke up the next day to discover that I had been sent my text message at about 9:30 with only 2 and a half hours left before the deadline.
Still, mustn’t grumble, at least the government is treating me like any other resident with regards to access to and cost of the vaccine.
