There is a lot of pseudoscience being spread on spike proteins made via the vaccines that is being extrapolated out of context from limited data on spike proteins made by the actual SARS-CoV-2 virus. Hope this helps address the
I am often asked what the impact of vaccination in pregnancy or lactation would be specific to passive transfer of antibodies and immunity. Here I try and outline the different types of antibodies, their function and what the subsequent impact would be on the fetus or
What exactly is vaccine efficacy? Efficacy is a measure of how well a vaccine works in clinical trials – specifically, the percent reduction of disease by comparing two groups – one that receives the vaccine and one that doesn’t, under favourable and tightly controlled settings. However, how one measures efficacy can vary significantly. Within the
Small increased risk of rare types of blood clots accompanied with thrombocytopenia (low platelets). Called ‘vaccine-induced prothrombotic immune thrombocytopenia’ or VIPIT. VIPIT is very rare. Initial estimates from Germany were 4 per million. Subsequent Norwegian estimates are 42 per million. Per Science Table estimates: occurring in anywhere from 1 in every 125,000 to 1 in
I have been getting a lot of questions on the AstraZeneca Oxford vaccine, and while data is evolving, here is some information Dr Elisabeth Marnik and I put together on its efficacy and safety. So far, it is very effective in preventing severe illness, hospitalization and death – both from clinical trial data as well
I’ve received many questions on NACI’s most recent recommendations on delaying second doses up to 4 months. This is a complex topic, but I think important to discuss for transparency. The only absolute in science is that there are no absolutes. Throughout the pandemic, evidence has evolved and recommendations have changed based on new data.
Johnson and Johnson’s COVID-19 vaccines becomes the 4th to receive Health Canada approval! 85% effective in preventing severe illness, 100% effective in preventing hospitalizations. Single dose, with data on efficacy in variants as well as preliminary data against asymptomatic disease. Best part – storage 2-8C. Will be a very valuable tool in our arsenal against
