The recommended age for the HPV vaccine is typically between 11 and 12 years, but it can be given as early as 9 years and up to 26 years. For the Hepatitis B vaccine, it is usually administered at birth, with follow-up doses in infancy. However, adults who have not been vaccinated should also receive it. The MMR vaccine is recommended during childhood, but women of reproductive age should ensure they are immune before becoming pregnant.
