The Northern Rivers Vaccination Supporters (NRVS) is a vaccination advocacy group formed in 2013 by people who were concerned about low vaccination rates in the Northern Rivers region of the Australian state of New South Wales. Rachel Heap, one of the group's core administrators, has said the organization's primary goal is to spread the word that people shouldn't be afraid of vaccines, but instead, "you should be amazed at how extraordinary they are as a public health measure".
