Unambiguous Science

We have simply not done a good job of explaining why masks protect the wearer, and instead have focused predominantly on how they protect others. A well-fitted mask that filters efficiently also blocks viral particles from being inhaled. We have also received a lot of pushback on aerosols, with people adamant about droplets being primary

I get a lot of questions on the difference between boosters/ third doses/ annual shots. The differences are mostly semantics, and can also overlap when it comes to Covid-19 vaccines. I also talk about why we may need boosters, what that means in terms of vaccine efficacy and how we need to be mindful about

A little Canadian update on where we are with submissions and approvals for pediatric vaccines as well as an update on what we are doing here regarding

New oral anti-viral therapy to treat covid-19 The MOVe-OUT study was a global, Phase 3, randomized, placebo-controlled study., A planned interim analysis showed that molnupiravir reduced the risk of hospitalization or death by ~50% compared to placebo in those with mild/moderate Covid-19 with at least one risk factor that puts them at a higher risk

As a precaution, NACI previously recommended that Covid-19 vaccines should be given at least 28 days before and 14 days after other vaccines. However, after reviewing new data and extensive experience, NACI has determined that this is no longer necessary. NACI now recommends that: COVID-19 vaccines may be given at the same time as, or

Remember, this is data by press release. Full data has not yet been released. N=2268, 2/3rd received Pfizer vaccine Dose: 10mcg (vs 30mcg for 12+), every 3 weeks Data showed robust neutralizing antibodies, similar to that in the positive control group (people aged 16-25 who received 30mcg vaccine dose) Data on vaccine efficacy not yet

How does an epidemic differ from a pandemic? When does a disease turn endemic? What are outbreaks? How do all of these pertain to Covid-19? I answer these frequently based questions in this

I receive many messages to clarify what the Interim Order pathway is, what happens when it expires and how it differs from the regular NDS/NOC. I explain what I know in this infographic. Health Canada is unfortunately not as transparent about the exact differences in requirements the way the FDA is, and while Interim Order

Recently a study from Israel showed that vaccinated people had a 5.96 fold increased risk for infections and a 7.13 fold increased risk for symptomatic disease compared to those who had previous Covid-19 infections and were unvaccinated. However, there are many limitations in this particular study, which I will outline below. Limitations: 1- There were
