Excellent Source

I found TWiV through the recommendation of another podcast. Like many I am a post covid follower and I have really appreciated TWiV as a source of current and accurate information. The clinical updates with Dr. Griffin are so useful . Dr Gritting uses language that I, a custodian i.e. not a science professional am able to understand. I find the clinical updates really ease my anxieties because finally I understand what is going on around me. Sometimes the other episodes I struggle to totally follow along but I always finish having learned something I didn't know before listening. Turns out virology and immunology is quite fascinating!

A good thing from the pandemic years

I discovered TWiV during 2020 due to the desire for more accurate and unbiased information about the viruses and then stayed for the good and interesting science. I never liked biology before but have found the discussions to be reasons to get interested in not only virology but biology, microbiology, even medicine. Although I don’t understand all the science, to hear the unfamiliar multiple times made them less intimidating and I feel like I am sitting in the same room as the host and guest scientists week after week when different topics are being discussed. The weekly clinical updates are also keeping me well informed about the viruses that we should be aware of in a timely way. Love this podcast and many sister podcasts from microbe.tv
