The damaging effects of influenza can be prevented by immunization, but constant changes of antigenic specificity of the virus necessitate a different composition of the vaccine (疫苗) from one year to another. The network of WHO surveillance activities to monitor the evaluation of influenza virus strains, and WHO hold an annual consultation at the end of February to recommend the composition of the vaccine for the forthcoming epidemiological season. These recommendations are published immediately in the weekly epidemiological record.
Vaccination each year against influenza is recommended for certain high-risk populations. In closed or semi-closed settings, maximum-benefit from immunization is likely to be achieved when more than three-quarters of the population are vaccinated so that the benefit of "herd immunity" can be exploited. Special care should be taken of the following groups:
—adults and children with chronic disorders of the pulmonary or cardiovascular systems requiring regular medical follow-up or who had been hospitalized during the previous year, including children with asthma;
—residents of nursing homes and other establishments for patients of any age with chronic medical conditions;
—all people over the age of 65.
Physicians, nurses, and other personel in primary and intensive care units, who are potentially capable of transmitting influenza to high risk persons, should be immunized; visiting nurses and volunteer workers providing home care to high-risk persons should also be included.

"I don't know all these people, "said his uncle.
"Then why do you wave to them？" asked Peter.
"Well , Peter, "answered his uncle," When I wave to someone and he knows me, he is pleased. He continues his journey with a happier heart. But when ! wave to someone and he doesn't know me, he is surprised and says to himself, ' Who is that man？ Why did he wave to me？' So he has something to think about during the rest of his journey, and it makes his journey seem shorter. So I make everybody happy."
