HALIFAX Nova Scotia is speeding up its rollout of the COVID-19 vaccine so that people who received their first dose of COVID-19 vaccine on or before April 10, and are scheduled to receive their second dose on or before July 24, can reschedule their appointments for earlier dates. We re expecting a large Moderna shipment this month, Dr. Robert Strang, Nova Scotia s chief medical officer of health said during a news conference Wednesday afternoon. We ll get to our 75 per cent of two doses of vaccine even faster. Strang said the province is sending out invites by e-mail to people to move up their second vaccine appointment.
