two-dose regimen

A two-dose regimen means receiving a vaccine in two separate injections spaced over a specific period. The first dose introduces your immune system to a safe piece of the virus or bacteria, helping it recognize and prepare. The second dose acts as a booster, reinforcing and strengthening this protection. Together, they ensure a more effective and durable immune response, offering better protection against the disease. This approach helps your body build stronger immunity, often resulting in higher overall immunity compared to a single dose.
