Why at least 8 weeks between COVID-19 vaccines for kids?

Share:

Health Canada approved the Pfizer-BioNTech vaccine for kids 5-11 today. But NACI’s recommendation for dose intervals is different from Health Canada’s approval. What’s up with that?

Health Canada authorizes vaccines based on clinical trial data. Pfizer tested the vaccines with 3 week intervals, so that’s what Health Canada approved. ✅

NACI recommends how best to use the authorized vaccine. An interval of at least 8 weeks may contribute added efficacy and safety on an already very safe, effective and high-quality vaccine.
