My cousin has been debating whether to have her daughter vaccinated against the HVP virus. I want to write her a message to encourage her to do so, as I have had to have a series of investigations for indications of pre-cancerous cells that have shown up when I have had smear tests (and I know I am very lucky that it has not been worse). I do feel strongly that my cousin should take all possible steps to protect her daughter from this, as I do not want anyone to go through what I have or worse.
Some of the message I want to send to my cousin includes links to medical research to correct some misapprehensions she has about the risk of contracting the virus- for example, that she is under the impression that it is the volume of sexual partners that causes the increased risk of contracting the virus, so it is impossible to catch it from just one partner; whereas actually the amount of sexual partners only increases the risk of sleeping with someone who carries the virus, and it is perfectly possible to catch it from just one sexual partner.
My cousin's reluctance to arrange for her daughter to have the vaccination comes from the fact that she is strongly religious, so would discourage her daughter from having sexual relationships outside marriage, and the fact that she and her family follow a lifestyle designed to promote health and well-being.
My dilemma is that I am also tempted to remind her that no matter how well she has brought her daughter up, teenagers are inclined to make mistakes and poor decisions. Although her daughter at the moment also follows her mother's beliefs and view of life, she may not always do so.
Do you think this last bit is necessary? Or a bit too preachy? Does it detract from the rest of what I want to say?
