Question

2.1. evaluate a scientific claim using the process described in the chapter, and find valid sources of information that help lead you to your conclusions. because the flu contains 18 different types of hemagglutinin, from h1 to h18, and 9 different types of neuraminidase, n1 to n9, it would take more than 150 years to get exposed to all possible combinations of hemagglutinins and neuraminidases. however, having the flu shot for several years is likely to protect you from future manifestations of the flu. which of the following provides the most logical explanation based on real scientific evidence for why this may be the case? multiple research studies published in scientific journals demonstrate that exposure to hemagglutinin 1 (h1) allows production of antibodies against h1. thus, if infected with the h1n7 flu, an h1 - vaccinated individual will have partial protection as the immune system will recognize this viruss hemagglutinin even if it does not recognize the n7 neuraminidase. an article published to an online - only blog claims that the flu shot will provide lifetime immunization against the flu. the article suggests that multiple flu shots in one lifetime do not provide further protection and can instead cause dangerous side effects, including cognitive and behavioral impairments. researchers predict that vaccination via a flu shot will provide some future protection, regardless of the type of flu virus. your mother says you need to get the flu shot as it will guarantee that you will not get the flu this year.

Explanation:

Scientific journals are reliable sources. Online - only blogs may lack peer - review. Predictions and personal advice are less conclusive.

Answer:

Multiple research studies published in scientific journals demonstrate that exposure to hemagglutinin 1 (H1) allows production of antibodies against H1. Thus, if infected with the H1N7 flu, an H1 - vaccinated individual will have partial protection as the immune system will recognize this virus’s hemagglutinin even if it does not recognize the N7 neuraminidase.
