AmericaSpeaks TheVoiceOfJoyce Virology Podcasts. They’re long and easy to understand! Good info on SARS COV2 Listened to 1st 45 min. Found out Roche serology test preferred, very sensitive, some people may test + for 2 months?, buy an Oximeter, test your oxygen levels & no one will recommend Vit D. Vit D works when you’re early stage Covid, then it helps the body fight the disease and that’s when you don’t want a boosted immune system. Do not use extra Vit D without a Dris knowledge & consent. This Podcast is preferred by scientists & clinicians. I’ve become a subscriber. Your choice.
