The Star asked several scientists, doctors and researchers to share their thoughts on the steps Ontarians can collectively take to avoid a fourth wave. “We know that with the Delta variant, one dose of vaccine is only 33 to 50 per cent effective,” Loh noted. Beyond the hot spot strategy, “getting more people fully vaccinated, full stop, is incredibly important,” said Ashleigh Tuite, an epidemiologist at the University of Toronto’s Dalla Lana School of Public Health. “I think this is really hard for everybody given we’re all ready to reopen ... but we need to go slowly,” he said. Allen said that Public Health Ontario is planning instead to emphasize whole-genomic testing, explaining that it would take time to develop a Delta-specific test.
