Alberta's Top Doc Says That Moderna's COVID-19 Vaccine Has The 'Highest Effectiveness'

"Pfizer follows close behind," said Hinshaw.

On Tuesday, July 22, Dr. Deena Hinshaw delivered an Alberta COVID-19 update to the public.

During her update, she noted that 70.8% of Alberta's eligible population have been vaccinated with at least one dose of a COVID-19 vaccine.

The health official went on to say that "I know some Albertans continue to wonder if they need to get the same brand of mRNA vaccine for first and second doses. To be clear, you do not. Pfizer and Moderna vaccines can be used interchangeably. It does not matter which brand you get for your second dose. They are both safe and effective and it is perfectly okay to get one dose of each."

She noted that Moderna shipments to the province have increased this month. She said that this is a good thing because "our data shows that over the past six months, Moderna has had the highest effectiveness of all vaccines with 93% protection against infections after a second dose. Pfizer follows close behind with 90% protection."

She said that both vaccines are "highly effective," urging Albertans to take the first vaccine that is available to them.
