Alberta Health Services says it is rescinding its COVID-19 immunization policy for its workers.
It says vaccines continue to provide strong protection against serious effects from COVID-19, but there is emerging evidence that the shots have become less protective against infection.
AHS says COVID-19 vaccines available to date target the original strain of the virus.
It says evidence shows that immunization without boosters has limited effectiveness in reducing transmission of the Omicron variants currently circulating.
“Health Minister Jason Copping and the UCP are pandering to an extreme anti-vaccine fringe in the party in the midst of the UCP leadership race, and putting patients and their families at risk.”
AHS says it will continue to monitor scientific evidence to assess the need for additional measures.
