More than a million people in the United States have been killed by COVID-19 in the past 3 years. The numbers would be much higher, but the vaccines were developed with amazing speed. Time and again, the vaccines have been shown to be safe and effective. Yet some people persist in claiming the mRNA vaccines are causing an epidemic of stroke. The data is clear. They do not. If you want to reduce your chances of stroke, get the vaccine. The new thing that causes stroke over the past few years is COVID-19 itself. If you want to decrease your chances of having a stroke (or another stroke) don't get a severe COVID-19 infection. And the simplest thing you can do to reduce your chances of getting a severe COVID-19 infection is to get the COVID-19 vaccine. If you do catch COVID-19 despite the vaccine, the data shows it will be much less severe and much less likely to be fatal.  In addition to protecting yourself, you are also helping to protect others who may not be medically eligible to get the vaccine. The COVID-19 mRNA vaccines are saving lives every day. In this episode ... In this episode, I talk with data scientist and epidemiologist Dr. Remle Crowe about the research studies coming out now that show what we already knew from earlier research: the COVID-19 vaccine does not increase your risk stroke. We talk about several studies, and we talk about how you can do your own research on the credibility of these studies and evaluate how well they reflect the scientific reality of our world. In this post, you'll also find links to a bunch of these studies that you can read for yourself. Start by listening to this conversation.

Dr. Remle Crowe is an expert in EMS research and quality improvement. From truck clutches to clinical care, she has shown how research and improvement science work to solve problems across fields. Prior to earning a PhD in Epidemiology, her EMS career began with the Red Cross in Mexico City as a volunteer EMT. She has authored numerous peer-reviewed publications related to prehospital care and the EMS workforce. Now, as a research scientist with ESO, Dr. Crowe routinely uses EMS data to improve community health and safety. Dr. Crowe previously appeared on the Strokecast in episode 132 to discuss the AHORA pneumonic to help Spanish speakers recognize and respond to a stroke. When it comes to stroke, Time is Brain regardless of which language you speak. A Sampling of the Studies When we claim the data indicates that the vaccine doesn't cause an increase in stroke, what data are we talking about? How did "they" analyze it? Who reviewed the studies to ensure they were accurate? Where can you read the details yourself? As Dr. Crowe explained, there are currently a whole bunch of studies that are coming out. That makes sense; it's roughly 18 months since the vaccines against COVID-19 became widely available. To conduct sound research, you need a large pool of people to look at. You need to take some time to see the results. You need to write up those results. Then you need to submit them for publication. Publications will then need to review before publishing them. That brings us to where we are today with all these studies now becoming available. Let's take a look at a few of them, and I encourage you to click through to the details and read them yourself.
