@alleycat Hi Kate, I'm 66. I received the first shot and was told there was a time gap before receiving the second one. I believe I'm due for the second one this year. I've never had pneumonia and don't remember the last time I had flu (maybe a mild one 30+ years ago). But I get flu shot every single year after I turned 50 without fail. With less than perfect lungs, I'm not taking any chances.
