Introduction to the AstraZeneca COVID-19 Vaccine
The AstraZeneca COVID-19 vaccine, also known as Covishield in some countries, is a viral vector vaccine that uses a weakened version of a common cold virus (adenovirus) that has been modified to include the genetic material of the SARS-CoV-2 virus. This modification allows the vaccine to instruct cells in the body to produce a specific protein, which then triggers an immune response without causing the disease itself. The vaccine has undergone rigorous testing and has been approved for emergency use in many countries due to its efficacy in preventing severe illness and hospitalization due to COVID-19.
How the Vaccine Works
The mechanism of action of the AstraZeneca COVID-19 vaccine involves the adenovirus vector entering cells and instructing them to produce the SARS-CoV-2 spike protein. The immune system recognizes this protein as foreign and mounts a response against it, producing antibodies and immune cells that can recognize and attack the SARS-CoV-2 virus if the individual is exposed to it in the future. This preemptive immune response is what provides protection against COVID-19.
