Starting today (Sat), the Saskatchewan Health Authority (SHA) is lowering the age eligibility for second doses to 70 years and older or anyone immunized on or before March 15th.

Second doses are also available to people diagnosed with or being treated for cancer or those who have received a solid organ transplant

The SHA says residents will be required to show the date of their first dose, which they say is noted on a card given to people on the day of first immunization.

The health authority also says the brand of second dose must be the same as the first.
