Shhh. The baby is asleep, so I have to type this really quietly.

In today’s post, I hope to address a few of the more common questions that both the public and the media have about the new COVID vaccines. As of now, we really only have data for three jabs: the Pfizer/Biontech one, the Moderna one, and the one produced in partnership between Astra Zeneca and Oxford University.

Well, 2020 is almost over, and of course COVID-19 throws us another curve ball to round out the year. The “new variant” that now dominates the news has arrived in Canada. Because I’ve had several media requests to comment on this development, let’s take a moment to take stock of what we know about this variant and what it might mean for our efforts to combat the epidemic.

COVID-19: No There Isn’t A PCR ‘Casedemic’

So, there is a prevalent claim that the COVID-19 cases being logged all across the world are horrendously overestimated, due to the hypersensitivity of the PCR test. Essentially, they state that what we are seeing is a “casedemic” and that there is no “second wave” and no pandemic at all. (more…)
