The World Health Organization’s Chief Scientist feels there is not enough information to understand the effects of mixing vaccines.

Soumya Swaminathan said Monday that there needs to be more data on what occurs when mixing vaccines.

“We’re in a data-free, evidence-free zone as far as a mix and match, there is limited data on mix and match,” explains Swaminathan. “There are studies going on, we need to wait for that and maybe it will be a very good approach.”

The comments were brought up during a vaccine donation announcement given by International Development Minister Karina Gould and Minister of Public Services and Procurement Anita Anand.

Gould believes Canadians should have faith in the local science, stressing their knowledge and qualifications.

“Health Canada is one of the top regulators in the world,” stated Gould. “NACI is comprised of some of the best experts that we have, so they’re making these decisions on the best science they have available.”

Anand echoes these thoughts, having faith in the research being done in Canada.

“I personally have had a mixed vaccine schedule, received Pfizer in the first instance and Moderna in the second instance,” explains Anand. “I have done so based on the science and will continue to follow the science and recommendations.”

Mixing vaccines has been happening in the country since it was approved by Health Canada in June.
