If a parent decided not to vaccinate their child, who in turn decided to get those vaccinations in adulthood, would they be as effective? Would the immune system be positively or negatively affected?

They should be as effective.

However, you are most likely to die from a disease that requires vaccination during your childhood since your immune system has yet to develop fully, so getting your shots as an adult requires surviving to adulthood.

If nothing else, it contributes to herd immunity and helps prevent pandemic outbreaks to have your vaccinations.
