Option 1: "There is now a special high-dose flu shot just for older people."
Explanation: This option accurately captures the main idea of the passage, which emphasizes the introduction of a specific vaccine, Fluzone High-Dose, designed for older individuals. The text highlights that this vaccine is created to enhance protection for those aged 65 and older, addressing their unique health needs. The mention of the vaccine's purpose and target demographic aligns perfectly with the overall theme of the passage.
Option 2: "Everyone over six months old should get flu shots this year."
Explanation: While the text does state that everyone over six months old should receive a flu shot, this option does not reflect the main focus of the passage. The primary emphasis is on the special vaccine for older adults, rather than the general recommendation for flu shots. Therefore, this option is too broad and does not capture the specific intent of the passage.
Option 3: "People over 65 years of age are more likely to contract the flu."
Explanation: This statement is not supported by the text. The passage discusses the immune response of older individuals and the need for a specialized vaccine, but it does not claim that they are more likely to contract the flu. This option misinterprets the information presented and does not align with the main idea.
Option 4: "Due to complications, no flu shot can protect an older person."
Explanation: This option contradicts the information in the text. The passage indicates that the new high-dose flu shot is specifically designed to provide better protection for older individuals, rather than suggesting that no flu shot can be effective. This misrepresentation of the text's message makes this option incorrect.
