Today marks the start of Week 2 of the H1N1 vaccine rollout and those eligible to receive the vaccine in B.C. will expand.
Those able to get shots Monday include frontline health-care workers, children between six months and five years of age, and caregivers of children under six months.
But health officials have warned that not all people in those groups will be able to get shots right away due to limited supplies.
Ottawa contracted with only one supplier: GlaxoSmithKline. The U.S. has five suppliers.
Federal Health Minister Leona Aglukkaq on Sunday urged Canadians to be patient.
"This is the largest immunization campaign in the history of Canada. Thirty-three million people cannot receive vaccine in seven days," she told CTV's Question Period.
Canadians have lined up by the thousands in the past week, overwhelming health-care workers.
Many clinics have had to cut off lineups hours before closing time in order to control the crowds.
B.C. has received a half-million doses of the H1N1 vaccine and expects to receive another shipment of 350,000 doses for distribution this week.
Week 1 of the vaccine rollout targeted high-risk groups, including pregnant women, people under 65 with chronic health conditions, and people living in remote areas. They are still able to get shots, if they haven't gotten one yet.
Health officials say the vaccine likely won't be available to the general population until late November or early December.
B.C. is in the midst of what officials have deemed a "second wave" of the H1N1 pandemic, and officials say it appears to be peaking.
However, officials expect a third wave.
"Influenza tends to wax and wane. And we also expect that we're going to have a third wave, after Christmas sometime, probably in the period starting in February," said Dr. Monika Naus of the BC Centre for Disease Control.
She said it's hard to predict how hard the third wave will hit.
