Should children have an hpv vaccination before they enroll in school?

Yes: Yes, if they are of age - meaning anywhere from 9-26 years old, i would highly recommend getting this vaccine. Its highly efficacious but only works if you get the vaccine prior to getting infected. Get the shot well before you "need" it for the best protection!

Age dependent: Children should have the hpv vaccine before they are at risk for needing it, any time after 9 years of age. Unfortunately, many parents do not know when their children are considering sex. Even more unfortunately, many children are sexually abused, which puts them at risk. Protecting your children against this virus that causes cancer is important!

Which grade U mean: Although this would likely work well if given to 5 & 6 it was never designed to be given at school entry. The data gathered to get the vaccine through the FDA approval process took years & included patients 9-26 which became the approved ages.Adding the earlier years to the FDA data would have added extra cost & delays to approval. Starting it before any sexual contact make sense.
