Alberta Health Services has declared the measles outbreak over in the Central and Calgary zones.
The outbreak declaration remains in effect in the Edmonton Zone of AHS.
The health agency says standard measles surveillance and follow-up will continue.
However, temporary changes to the routine childhood immunization schedule — implemented for the outbreak — are no longer in effect in Central and Calgary zones.
Effective immediately, AHS will no longer offer an early additional dose of measles vaccine to infants six months of age to less than 12 months of age who are living in or travelling to the Central or Calgary Zones of AHS.
This additional early dose of the vaccine was recommended while the outbreak was active in both of these zones to provide short-term added protection during a time of increased risk of exposure.
Requests for early additional doses of the vaccine will no longer be accommodated in either zone.
However, infants travelling to the Edmonton zone or any other areas within Canada or abroad in which measles outbreaks are occurring are still eligible to receive an additional early dose of vaccine if this travel cannot be avoided.
Health officials point out that measles continues to circulate in Alberta and worldwide. Without immunization, Albertans may be at risk of contracting this potentially severe illness.
All Albertans born during or after 1970 require two doses of measles vaccine to be protected.
