Host Jeremy Quinby invites Dr. Jeff Crippen back to the show to help us all with a game plan for improving immune function for the cold and flu season. A new strain of Covid-19 is also making a return. Jeremy and Jeff discuss science that has been gathered over the past 3 years in how our immune systems can protect us from Covid and RSV and what we now understand to be the top reasons for long-covid symtoms. https://crippenwellness.com https://www.amazon.com/s?k=timeless+youth+jeff+crippen&crid=3KMUZZE7QY0NG&sprefix=timeless+you%2Caps%2C260&ref=nb_sb_ss_ts-doa-p_1_12
