human papillomavirus prophylaxis
"I don't know about the efficacy of this vaccine but I had no issues with the shot itself. It stung maybe slightly more than a flu vaccine but not bad. I had no other side effects. I got it in my 20s. My son got the vaccine too and his experience was similar - no issues. It seems to be a well-researched vaccine with a good safety record and HPV is so common these days that I think it's a good idea."
