I really like the daily video updates by Dr John Campbell (a retired nurse from England). His videos are informative and scientifically-based. His tone is not so optimistic because he feels many Governments are still reactive, rather than proactive in responding to the COVID-19 situation. If you don't want to watch the daily updates, he has lots of excellent videos explaining terms and areas of scientific interest for the layperson. For example, I posted a link elsewhere to a informative video he created today on vitamin D and it's beneficial effect against respiratory conditions. You'll find this and all his videos here: https://www.youtube.com/user/Campbellteaching/videos https://www.youtube.com/user/Campbellteaching/videos
