'Infection doesn't protect you': Getting COVID twice more common as immunity wanes, experts say

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.

"I started feeling sick three to four days ago thinking, 'This feels like COVID.' I took five tests and ... today it came back positive," the bakery owner said Friday from her home in Warren, Mba., about 45 kilometres north of Winnipeg.

"It did come as a surprise to me because of all the things I put in place to not get it. Now that I had it twice, I don't feel quite as invincible."

Reinfection of COVID-19 was considered unusual, but then the Omicron variant arrived.
