Alberta Health Services has set aside additional doses of influenza vaccine for some of the most vulnerable residents in the province.

The additional doses are available for children who turned, or will turn, six months of age on or after Dec. 1, 2013, to March 31, 2014.

"By offering vaccine to this group of infants who would not have previously had the opportunity to receive vaccine through routine programs this year, AHS is ensuring that the additional doses of vaccine secured by the province for use in Alberta are being administered to this vulnerable group," said officials in a statement on Monday.

It's also not counting the doses set aside for children under the age of nine who got a first dose of the vaccine and still require a second dose this season.

Children who received flu vaccine for the first time this season require two doses to be fully immunized.

Parents with children in these groups can set up an appointment by calling Health Link Alberta at 1-866-408-5465.

There is currently a shortage of flu vaccine in the province after a record number of Albertans braved long lineups at clinics in January to get their shot.
