Common Language Description

The CPT® Code 91311 refers to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine, specifically designed to combat coronavirus disease (COVID-19). This vaccine utilizes a novel approach by employing messenger RNA (mRNA) encapsulated in lipid nanoparticles (LNP), which is a cutting-edge technology in vaccine development. The mRNA contained in the vaccine encodes the spike protein of the SARS-CoV-2 virus, which is critical for the virus's ability to infect human cells. Upon administration, the vaccine instructs the body's cells to produce copies of this spike protein, prompting the immune system to recognize it as a foreign entity. This recognition triggers an immune response, leading to the production of antibodies that can neutralize the virus if the individual is exposed in the future. The vaccine is preservative-free and is administered in a dosage of 25 mcg per 0.25 mL via intramuscular injection. It is specifically indicated for a two-dose vaccination regimen for pediatric patients aged 6 months to 5 years, providing essential protection against the potentially severe and life-threatening effects of COVID-19 in this vulnerable age group.
