The Ministry of Health is showing us today how the AstraZeneca vaccine works for immunization against the Coronavirus, and below you can see exactly what happens after it enters the body of an immunized person.
"How does the AstraZeneca vaccine work?
AstraZeneca's COVID-19 vaccine contains a non-human adenovirus that cannot replicate and cause disease.
The adenovirus has been modified to contain the information needed to produce the spike protein (the one found on the surface of the SARS-CoV-2 virus). Once the vaccine is administered, the adenovirus delivers this information to human cells, which begin producing the spike protein.
The person's immune system will treat this spike protein as foreign and produce an immune response – antibodies and T cells – against it.
If the vaccinated person comes into contact with the SARS-CoV-2 virus, the immune system will recognize it and be prepared to attack it: antibodies and T cells will work together to"
