The H1N1 flu shot is ready to go and has already been distributed to the provinces and territories and more will be ready in the coming days.

The vaccine is still waiting for approval from Health Canada before Canadians can be immunized but that process is well underway and clinics are standing by.

Health officials have ordered 50 million doses of the H1N1 vaccine and there's enough for everyone who wants it, free of charge.

Alberta clinics will have to change direction when the vaccine becomes available and exchange the seasonal shots for the H1N1 vaccine.

Two versions of the vaccine will eventually be available, one with adjuvant and one without.

Adjuvant is used to stimulate the immune system and may increase the body's response to the vaccine.

The vaccine without adjuvant is recommended for pregnant woman but health officials say both vaccines are safe for expectant mothers.
