Here is a partial shot of the line waiting for H1N1 vaccination at Avenida in Calgary on October 26, 2009. At the time of this photo (about 1 PM) the wait was about 4 to 5 hours. In Okotoks, the wait was only 2 hours (they had 16 nurses on duty). So although we don't advocate it, perhaps a short drive would be worthwhile.
Update: flu clinics suspended - urgency is now being downplayed
