I recenlty quit smoking about 6 months ago. Since then I have been using zyn nicotine pouches to help me out. From what I know they do not have tobacco in them but I could be wrong. Yesterday I got my first dose of the Pfizer vaccine. Not thinking I threw in a pouch about 3 hours after. I'm wondering if using the pouches after getting the vaccine can lessen the effect of the vaccine. I've looked online and all I can find is studies about actual smoking. Does anyone know if using these pouches messes up the immune response to the vaccine?
