Moderna's COVID-19 vaccine helps antibodies last for 3 months: Study

Moderna's coronavirus vaccine causes the human immune system to produce potent antibodies that endure for at least three months, according to a study published in the New England Journal of Medicine. Researchers studied the immune response of 34 adult participants from the first stage of a clinical trial. The vaccine, mRNA-1273, is administered in two injections given 28 days apart.
