How Do These Vaccines Work to Protect Against COVID-19?

COVID-19 vaccines work by priming the immune system to recognize and fight the virus that causes COVID-19, ultimately reducing the risk of severe illness. These vaccines utilize different mechanisms, but they mainly focus on training the immune response without causing the disease itself.

  1. mRNA vaccines (e.g., Pfizer-BioNTech and Moderna):
    – Mechanism: mRNA vaccines use messenger RNA to instruct cells to produce a harmless piece of the spike protein found on the surface of the SARS-CoV-2 virus.
    – Immune Response: Once the spike protein is produced, the immune system recognizes it as foreign and generates an immune response. This includes producing antibodies and activating T-cells.
    – Efficacy: Clinical trials demonstrated effectiveness rates up to 95% in preventing COVID-19 infection in healthy individuals (Baden et al., 2021).

  2. Viral vector vaccines (e.g., Johnson & Johnson):
    – Mechanism: These vaccines use a harmless virus as a delivery system (vector) to carry the genetic material coding for the SARS-CoV-2 spike protein into cells.
    – Immune Response: Similar to mRNA vaccines, this prompts the body to create the spike protein, triggering an immune response that includes antibody production.
    – Efficacy: Studies indicated that Johnson & Johnson’s vaccine provided about 66% protection against moderate to severe COVID-19 (Sadoff et al., 2021).

  3. Protein subunit vaccines (e.g., Novavax):
    – Mechanism: Protein subunit vaccines contain harmless pieces of the SARS-CoV-2 virus (spike proteins) instead of the entire virus.
    – Immune Response: The immune system recognizes these proteins as foreign, leading to antibody production and T-cell activation.
    – Efficacy: Clinical trials revealed that the Novavax vaccine had an efficacy rate of around 90% in preventing symptomatic COVID-19 (Bansal et al., 2022).

  4. Inactivated or live-attenuated vaccines (e.g., Sinovac and Sinopharm):
    – Mechanism: These vaccines contain killed virus or a weakened form of the virus. They cannot cause disease but stimulate an immune response.
    – Immune Response: They induce the body to recognize the virus and develop immunity through the production of antibodies.
    – Efficacy: Research indicates varied efficacy rates, often between 50% to 85%, depending on the specific formulation and population studied (Mina et al., 2021).

In summary, COVID-19 vaccines effectively prepare the immune system to respond to the virus. This preparation prevents severe illness and curtails the spread of the disease in the population, thus making vaccination a critical tool in managing the COVID-19 pandemic.
