Early research suggests a concerning percentage of recovered COVID-19 patients have been left with a chronic respiratory condition called pulmonary fibrosis.

Pfizer's previous vaccinetargeted an earlier subvariant of Omicron called XBB.1.5.

Guidance from theNational Advisory Committee on Immunization(NACI) strongly recommends updated COVID-19 vaccinations starting this fall for high-risk groups, including adults 65 and older, people living in long-term care and other group living settings, people with underlying conditions that put them at higher risk of severe illness, people from Indigenous and racialized communities, and those who are pregnant or who provide essential community services.

NACI said all other adults and children six months or oldershould also be eligible for an updated COVID-19 vaccination this fall.

According to the Public Health Agency of Canada's wastewater data, updated on Tuesday, COVID-19 viral activity is moderate on a national level, but some wastewater collection points in Yukon, British Columbia, Manitoba, New Brunswick and Newfoundland and Labrador have registered high levels of activity as of Sept. 8.

Wastewater testing offers an early indicator of when respiratory viruses are on the rise, doctors and epidemiologists say.

Both the latest Pfizer and Moderna vaccines are approved for adults and for children six months of age and older.

Novavax is approved for adults and those aged 12 years and up.
