Discuss the how different types of vaccines trigger an immune response

The above link has four-part animation series that explores the biology of the virus, including the structure of coronaviruses like SARS-CoV-2, how they infect humans and replicate inside cells, how the viruses evolve, methods used to detect active and past SARS-CoV-2 infections, and how different types of vaccinations for SARS-CoV-2 prevent disease. 

After watching all parts of the animation,

Discuss any two of the following 4 prompts

1. The replication process of SARs-COV-2, describing the different steps involved.
2. How mutations arise in viral genome and how it changes the virus over time.
3. Discuss the different ways to detect viral infection
4. Discuss the how different types of vaccines trigger an immune response

Also include a short paragraph on

• Did this animation help to correct any misconceptions you had about SARS CoV-2 or Covid-19?
