Reaching Herd Immunity During the SARS-CoV-2 Pandemic: What School Nurses Need to Know.

ABSTRACT

The National Association of School Nurses supports pandemic control efforts. School nurses are advocates for their students, caregivers, school staff, teachers, and school administrators. With a clear understanding of how the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus evolves over time and changes transmissibility through mutations, school nurses gain understanding in epidemiologic calculation of herd immunity. To understand why the estimates of herd immunity fluctuate, as often reported in the news, school nurses need to understand how epidemiologist calculate this number. Obtaining herd immunity will protect the most vulnerable in the population. If all countries have access to vaccines and populations choose to receive vaccinations, herd immunity is more likely to be obtained. Equipped with knowledge of how herd immunity is calculated, school nurses are in a position to educate and advocate for the use of vaccines.
