Karnie Sharp and James Reynolds hear from two Americans who regret their decisions - including the man who almost died and ended up with a double lung transplant after catching the disease. We also hear from flight attendants in Nigeria, Spain and the US about dealing with unruly passengers during a pandemic - especially when asked to wear a mask. Plus a scientist in Uganda explains the vaccine situation there during the country’s second wave.
