My wife doesn't want the vaccine. She had covid at the same time I did but just had some minor symptoms. The odd thing She smokes a pack of cigarettes a day. My infectious doctor said he believes nicotine plays a roll of lessening the symptoms. I told him I quit smoking 17 years ago but wasn't opposed to taking up the habit again if it would help. That got a chuckle and a response of no, don't do that. There I was thinking I had a good reason to enjoy a smooth Marlboro red again...
