Question

Take a moment and reflect on what you've learned from chapters 12-13 and use this knowledge to investigate how the new Pfizer COVID-19 vaccine might work to stimulate the immune system. Discuss how the mRNA-based vaccine strategy may effectively induce BOTH a humoral and cellular immune response and talk about the key players. You'll need to take some time to learn a bit more about the vaccine if you're unfamiliar with the mRNA-based approach before answering this question.

Answer 1

1.Why there is Pfizer

mRNA a molecule type modern kind of vaccination process. it is safe and very effective to infectious diseases but this very is fragile and would destroyed by our natural body enzymes if it is directly injected to body, or it may destroyed in the normal temperature.

Pfizer tablets like a container, keeps this mRNA molecules in a oily and cooling shells to enter the body safely and fight aginst infection /viral diseases.

2.mRNA Vaccines

It is long lasting immune response and thus vaccines have potential to be quick manufactured and to become powerful tool against infectious diseases. Well-tolerability and

safety is main features of this mRNA vaccines.

According to study vaccine is injected to body and it enables human cell to produce protein part of SARS-CoV-2 receptor-binding domain against which the immune system trained to produce antibodies.

This type of vsccines can be produced synthetically through cell-free enzymatic transcription reaction.
