Prevention of COVID-19 caused by SARS-CoV-2 in adults and adolescents (age varies by specific vaccine product). Used for primary vaccination series and booster doses.
Contains recombinant SARS-CoV-2 spike protein produced without use of the live virus. The protein is presented with an adjuvant to enhance immune response, training the body to recognize and fight the actual virus if exposed.
Like all vaccines, protection develops over time (typically 1-2 weeks after final primary series dose). Common side effects include injection site pain, fatigue, headache, and muscle aches. Serious allergic reactions are rare but possible. Does not contain preservatives like thimerosal. Consult current official guidelines for age indications and dosing schedules.
