Getting infected with COVID-19 for a second time is becoming increasingly more common as people's immunity wanes, experts say.
Enns, who received two doses of COVID-19 vaccine and a booster shot, already had the virus in early February and thought reinfection was rare.
"Because Omicron is so different, previous infection doesn't protect you," Saskatchewan's chief medical health officer, Dr. Saqib Shahab, said last week. Quebec's National Institute of Public Health says the number of presumed reinfections has increased greatly in its province since Omicron arrived. "Not only is it able to escape immunity, but it is happening at a time where people's immunity is waning," Muhajarine said, adding it has been three to five months since most Canadians have completed their two-dose vaccine series.
