It's absurd that you can't get the vaccine past age 45. I've read that the reasoning is that people beyond that age are "likely" to have already been exposed. Except there are many strains of HPV, and exposure to one may not protect from others. There are also plenty of people who've managed to avoid it by age 45, but who could still be exposed later in life. Especially because condoms for birth control purposes aren't necessary in late life. STD rates at some of these retirement villages are out of control.
