Social Studies
1 answer:
denis-greek [22]1 year ago
7 0

The reason why one case of influenza does not confer lifelong immunity is that the virus tends to mutate overtime which makes it unrecognizable to the immune system.

<h3>Why is it difficult to get immunity to influenza?</h3>

Influenza is caused by a virus which tends to mutate overtime in order to stay ahead of medical technology.

As a result, this mutation makes the original virus unrecognizable to the immune system which would then be unable to fight it.
