Share on Twitter Australia is ramping up its vaccination program following criticism it's lagging behind schedule, with the number of general practice clinics offering the jab expected to double from 1,500 to 3,000 this week and rise to 4,000 sites by the end of the month. Acting Chief Medical Officer Professor Michael Kidd told reporters on Monday the push comes after four consecutive record days last week when it came to doses given. "In the past two weeks, working with our other vaccination delivery sites and teams, our nation's GPs helped to triple the number of doses of vaccine delivered in two weeks from 250,000 a week to over 840,000 in the last week," Professor Kidd said.
