Coronavirus Vaccine Goes Into Phase 1 Trial
The first patients in Seattle, WA have been injected with a novel vaccine aimed at curbing COVID-19 infections in humans. The vaccine was introduced to a cohort of patients yesterday in hopes that it will trigger immunity to the rapidly developing virus.
Volunteers between 18 and 55 years old at the Kaiser Permanente Washington Health Research Institute were given the first of two doses of the vaccine, now being called mRNA-1273. This vaccine aims to alert the body’s immune system to a surface protein expressed on the 2019 coronavirus known as Spike.
The experiemental vaccine mRNA-1273 seeks to accomplish this by injecting people with the precursor mRNA that encodes the spike protein in coronavirus. Essentially, upon injection this will allow the body to translate those mRNA molecules into free floating spike proteins, which researchers hope is sufficient to trigger the body’s natural adaptive immune response against COVID-19.
Vaccines must strike a delicate balance between being potent enough to trigger a strong immune response, while not being so potent to cause adverse effects. This vaccine, being that it only introduces the spike protein into the…
