On the afternoon of June 22, 2021, the entire PHS school received the first dose of the Covid-19 vaccine.
The vaccine injected is the AstraZeneca vaccine, produced by vector mechanism, that is, the vaccine uses the chimpanzee’s adenovirus that has lost the ability to replicate, based on a weakened version of the adenovirus (the influenza virus that causes flu in chimpanzees), containing genetic material which is the spike protein on the surface of the SARS-CoV-2 virus that causes COVID-19 called Spike or S. Protein. On the other hand, Spike is the pioneer ingredient that opens the way for the SARS-CoV-2 virus to invade the human body and is also the target of the immune system’s attack when the SARS-CoV-2 virus invades.
After vaccination, the spike protein is produced, and the immune system continues to make memory cells. These cells will detect the SARS-CoV-2 virus if it attacks the body in the future, by recognizing the spike protein on the surface of the virus. If immune cells pass through the SARS-CoV-2 virus in the body, they will produce many antibodies and T cells very quickly, which prevents the virus from spreading and reduces complications and dangers from the disease caused by COVID-19.
