Would vaccinations be an example of a public good?

Vaccinations can be considered a public good because they provide benefits that extend beyond the individual receiving the vaccine, contributing to herd immunity and protecting the wider community from disease outbreaks. However, they do not fully meet the criteria of a public good, as they are excludable and rivalrous to some extent, given that vaccines require resources and infrastructure for distribution. Thus, while vaccinations have significant public health benefits, they are not a perfect example of a traditional public good.
