What are flu vaccine options?

• A. Live attenuated and subunit vaccines
• B. Standard dose, high-dose, and recombinant flu vaccines
• C. Oral and nasal vaccines
• D. Annual and biannual vaccines

Answer: (B)

Flu vaccine options include standard dose, high-dose, and recombinant flu vaccines, making this option the most accurate. Standard dose vaccines are typically administered to the general population and contain the reduced antigen level necessary for a basic immune response. High-dose vaccines are specifically designed for older adults, who may have a weaker immune response, and contain a higher concentration of antigens to elicit a stronger immune reaction. Recombinant flu vaccines are produced using a method that does not involve the live virus. Instead, they use a genetic sequencing technique that allows for a quicker response to changing flu strains and can be an option for individuals with egg allergies, as these vaccines do not require the use of eggs in their production. Other choices do not accurately represent the main classifications of flu vaccines. Live attenuated vaccines are indeed one type of flu vaccine option, but they don't encompass all available vaccines, and the specific forms like the intranasal vaccine are included as types rather than standard classifications in the provided answer. The choice mentioning oral and nasal vaccines misrepresents the delivery methods rather than clearly categorizing the vaccine forms. Lastly, describing flu vaccines as annual or biannual relates to the frequency of vaccination rather than distinct vaccine types. Thus, the focus on the variations of
