Pfizer Or Moderna? A Doctor Says One Has A 'Longer-Lasting Response' But Both 'Are Fine'

The top doctor in B.C. compared the Pfizer and Moderna vaccines and said that one has a "stronger" effect.

If you're planning to get your booster dose soon, you might be wondering if there's a difference between the COVID-19 vaccines, especially with the emergence of the Omicron variant.

Dr. Bonnie Henry answered some questions in a town hall video on Monday night that was livestreamed on the Global BC Facebook page, including one concerning the Pfizer vaccine compared to the Moderna vaccine.

She said that both vaccines "are fine," and that Canada has been a leader in "learning about mixing and matching of vaccines and how effective that can be."

"I will say there is some evidence that Moderna gives a stronger, longer-lasting response," she added.

Although it is limited, some research has even suggested "that Moderna probably is the best — strongest — for a booster. But either one is really great," she said.

She said that mixing vaccines is fine to do and that you can take whatever vaccine is available.

She also addressed a question on when you should get your booster if you have tested positive for COVID-19.

"As soon as you're feeling better, go ahead and get your booster dose," Dr. Henry said.

Not only can you go get the booster but "people who've had vaccine and infection and then get their booster dose are basically super immune," she explained.

She added that based on what they have been seeing, they think that these "are the people who are most protected over time.”

The B.C. government recently sped up the booster dose plan, and people can book their appointment when they receive an invitation.
