Many teens cite a desire to get a COVID vaccine in order to do their part and protect the health of those more vulnerable in their families and communities.
Older adults are more likely to make an effort to help others, a new study reports.

As early as 19 months of age, children start to show altruistic behaviors. The study reports even when a small child is hungry, they will give their snack to a stranger in need. Findings reveal not only do young children engage in altruistic behavior, but early social experiences can also help shape future altruistic behaviors.
