The control of COVID-19 may require regular booster vaccinations
Most people today are immune to SARS-CoV-2, the coronavirus that causes COVID-19, thanks to widespread vaccination campaigns and unplanned infection. Although this widespread immunity hasn't stopped new infections from happening, it has slowed the devastating spread of illness and death that the initial COVID-19 epidemic caused. As the virus evolves and produces novel strains that can partially dodge vaccines and antibodies created by past infections, it is imperative that this degree of protection be maintained.
