And then the balance of the vaccination program will shift to second doses – and it will significantly pick up pace,” he said.”When the nation moves forward with the national plan and crosses the 70 per cent vaccination threshold in mid-late October, and the 80 per cent vaccination threshold in early-mid November, the ACT’s vaccination program will put our city in a very strong position to gradually reopen.”We will support the work that is being undertaken nationally and locally to achieve a COVID-normal life as soon as is possible.”But Mr Barr acknowledged yesterday’s announcement that the lockdown would be extended was difficult to hear for some Canberrans.”This is one of the toughest moments in our city’s history, and I want people to know it is okay to reach out and ask for help if you need it,” Mr Barr said.”There will be better times ahead for Canberra.”Our vaccination milestones are in sight, and our objective through all of this is to keep our community safe and to work towards a safe and happy Christmas, and summer holiday period for everyone.” ACT health authorities say they are concerned that there are unidentified cases of COVID-19 out in the community. (ABC News: Ian Cutmore)Unknown cases still out in community, health authorities sayACT Deputy Chief Health Officer Vanessa Johnston said due to a large number of unlinked cases, it was likely there were cases in the community that had not been found.”We are still seeing people infectious in the community, some of whom are attending essential work while infectious,” Mr Barr said.“If we were to relax our restrictions now, we risk this outbreak rapidly escalating when not enough of us are vaccinated and therefore we would see a proportion of cases with severe disease outcomes including hospitalisation, ICU admissions and even death.”Dr Johnston said it was important Canberrans stayed the course over the next few months.”We all acknowledge and respect that lockdown is hard, and acknowledge the sentiment in the community and the disappointment after yesterday’s announcement,” she said.”If we continue to do the right thing now, if we stay the course, we’ll be in a much stronger position to come out of the lockdown in the weeks to come.”More to come.
