Answer 2

Hi there,

I hope you and your family are staying safe and healthy during this anomalous time.

The Correct Answer is A

Answer: Influenza is so strong that you need a booster every year to make sure your body can fight it.

It's kinda similar to the current pandemic where they recommend a Booster even after people got vaccinated twice. The reason is that the virus changes, it gets stronger. By then, the scientist also discovered better ways to create the vaccination to make it stronger and more suitable.
