For many months now, COVID testing has become a part of everyday life. Beyond identifying if you have COVID, the tests have very little additional use. They don’t provide information we have come to expect from the battery of routine medical tests we are subjected to through our lifetime.  We need global standards for testing, […]

The way COVID-19 vaccines protect us is still not fully understood. Nor is the level of protection achieved by the various vaccines. Studies are now emerging highlighting the confusion in the community about what constitutes vaccine efficacy. There is a common misconception that vaccine efficacy is measured by the vaccine’s ability to prevent us from […]

Now that the saner populations of the world are reaching a critical mass of  vaccination against COVID, our attention must turn to whether booster vaccinations are necessary. And as with everything emerging about COVID, it is a rapidly changing picture. Choose a different vaccine to boost and only one dose Eleven years ago, US Infectious Disease […]

Vaccines are the best news to emerge from the ongoing COVID-19 pandemic. The rapid and successful deployment of the new vaccines offers a way to limit the devastating effects of the pandemic – for men at least.  Unfortunately, the recent reports of thromboembolic events (clotting) may raise new concerns amongst the unvaccinated. These reports initiated with vaccines […]

Vaccine hesitancy is a real problem in the control of mortality from COVID. It is true that we know very little about the safety of these new generation mRNA vaccines. However, we do know that mRNA vaccines are safer than previous generations of nucleotide vaccines that were based on DNA and therefore could be integrated into our […]

As a public health physician, and as a family physician, I am ashamed. In response to COVID, my colleagues in public health officialdom are losing credibility as they search for politically driven quick fixes and remain silent when individual freedoms are restricted without clear evidence of an enduring relationship to positive outcomes. COVID is here […]

Countries worldwide are racing to vaccinate a significant proportion of their populations against COVID in the coming months. The evidence that vaccination decreases the likelihood of severe disease is promising. What is not so clear is whether the vaccines will eradicate the pandemic. To date there has been very little research into whether the vaccines […]

The COVID context is changing rapidly with the virus mutating and vaccination programs being rolled out globally. The original evidence on vaccine trials still stands. Here is a summary of what we know to date, which is supported by research evidence and not baseless assertion nor media factoid. As always, the primary references are available […]

To date, none of the available vaccines prevent transmission from one individual to another. Most focus on decreasing the severity of symptoms. In the short term, that is a very effective strategy. In the longer term it can turn into a double-edged sword.  Evolving new strains of COVID may be more beneficial than detrimental. Consider […]
