I was vaping nicotine the time I had my father with covid and still got it. It didn't protect me.
When somebody has covid or the flu, he should avoid taking nicotine at whichever form (vaping, smoking etc) because:
"The study found that vaping with nicotine impairs ciliary beat frequency, dehydrates airway fluid and makes mucus more viscous or sticky. These changes make it more difficult for the bronchi, the main passageways to the lung, to defend themselves from infection and injury"
