LETHBRIDGE, Alta. - Health officials in southern Alberta have resumed vaccinations for young adults to stop the spread of mumps after a vaccine scare last year.

Last month, Health Canada cleared several lots of mumps vaccine that had come into question after six young people in Alberta had allergic reactions after being inoculated.

Vaccinations had been put on hold in December while the federal department investigated.

Dr. Karen Grimsrud says immunizations have resumed in the Chinook Health Region, where most of the province's mumps cases have surfaced.

A program to immunize adults will resume province-wide next month.

Since last September, 439 cases of the mumps have been reported in Alberta, with 279 of them reported in the Chinook Health Region.
