There is some evidence, however, that immunity may decline more quickly in older people. For older adults, two vaccine options are available. One of these options is a “high-dose” vaccine, which is designed specifically for people 65 and older. This vaccine contains a higher dose of antigen (the part of the vaccine that prompts the body to make antibody), which is intended to create a stronger immune response in this age group. For more information, see Fluzone® High-Dose Seasonal Influenza Vaccine Questions and Answers . Another option licensed is an adjuvanted flu vaccine (FLUAD™). FLUAD™ is a trivalent vaccine made with MF59 adjuvant for use in persons aged 65 years and older. (FLUAD™ is the first adjuvanted influenza vaccine marketed in the United States.) For more information, see FLUAD™ Flu Vaccine with Adjuvant .
To avoid this, people should stay away from sick people and stay home if sick. It also is important to wash hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand rub. Linens, eating utensils, and dishes belonging to those who are sick should not be shared without washing thoroughly first. Eating utensils can be washed either in a dishwasher or by hand with water and soap and do not need to be cleaned separately. Further, frequently touched surfaces should be cleaned and disinfected at home, work and school, especially if someone is ill.
