Does anyone know if nvic.org is a reliable website?

Is the national vaccine information center (nvic.org) a reliable source of real information? Just trying to learn more about vaccines. Myself and my husband are fully on board with vaccines, but recently I mentioned getting our flu vaccinations to a family member who told me that she would never get the flu shot because one of her friends had died from it. I’m basically trying to gather information that the benefits outweigh the risks and that the likelihood of that happening is very very low. I found some information about the flu vaccines and reactions on this website and I’m wondering if anyone knows if it’s a reliable source as there are so many false claims online regarding vaccines.
