Been getting the flu shot for a while now. Haven't had it since I started, but that may be as much about my lifestyle as anything else. We don't go out much, and when I shop, I use wipes on the cart and my hands, don't touch my face until I get home and wash. No colds either. Because of my age, I get a bigger dose of the vaccine.
Finished the shingles shots last month. That one kicks my butt for a couple of days, but nothing compared to shingles.
