MIDDLESEX CENTRE, ONT. The London Public Library and Middlesex County Library are stepping in to help health officials reach area residents age 70 and older who have not yet been vaccinated. The Middlesex-London Health Unit (MLHU) announced the new collaboration Monday as part of an effort to reach people who are eligible but have not booked an appointment. To date, nearly 140,000 shots have been delivered at the region s three vaccination centres. In addition, more than 80 percent of people over the age of 80 and 65 percent of those 70-74 years old are estimated to have already received their first dose. But health officials want to see those percentages go higher.
