A common way to prevent infectious viral diseases, such as COVID-19 and the flu, is to the virus that causes them. Vaccines can be made from a virus's proteins or other parts, has been inactivated and is no longer harmful. Some vaccines, such as the flu vaccine, n every year to keep up with changes in the virus. Studies have shown that SARS-CoV-2 has a slower mutation rate than the influenza viru: flu. This means that mutations occur less frequently in SARS-CoV-2's genome than in the genome.

Question
Explanation please
A common way to prevent infectious viral diseases, such as COVID-19 and the flu, is to develop a vaccine for
the virus that causes them. Vaccines can be made from a virus's proteins or other parts, or from a virus that
has been inactivated and is no longer harmful. Some vaccines, such as the flu vaccine, need to be modified
every year to keep up with changes in the virus.
Studies have shown that SARS-CoV-2 has a slower mutation rate than the influenza virus, which causes the
flu. This means that mutations occur less frequently in SARS-CoV-2's genome than in the influenza virus's
genome.
Scientists at Arizona State University sequenced SARS-CoV-2 genomes collected from hundreds of
infected individuals. They found a deletion of 81 nucleotides in some of the viruses. This large deletion is
in a gene that codes for a protein that helps the virus escape the immune system.
8. Predict how the frequency of viruses with this deletion will change in the population over time.
Use evidence to support your answer.
