Influenza vaccines,also known as flu shots,are vaccines that protect against infection by influenza viruses. New versions of the vaccines are developed twice a year,as the influenza virus rapidly changes. While their effectiveness varies from year to year,most provide modest to high protection against influenza. The United States Centers for Disease Control and Prevention (CDC) estimates that vaccination against influenza reduces sickness,medical visits,hospitalizations,and deaths. Immunized workers who do catch the flu return to work half a day sooner on average. Vaccine effectiveness in those over 65 years old remains uncertain due to a lack of high-quality research.
The Hong Kong flu,also known as the 1968 flu pandemic,was a flu pandemic whose outbreak in 1968 and 1969 killed between one and four million people globally. It is among the deadliest pandemics in history,and was caused by an H3N2 strain of the influenza A virus. The virus was descended from H2N2 through antigenic shift,a genetic process in which genes from multiple subtypes are reassorted to form a new virus.

Australia had 37,537 confirmed cases of H1N1 Influenza 2009 and 191 deaths reported by Department of Health but only 77 deaths reported by the Australian Bureau of Statistics. The actual numbers are much larger,as only serious cases warranted being tested and treated at the time. Suspected cases have not been reported by the Department of Health and Ageing since 18 May 2009 because they were changing too quickly to report. Sources say that as many as 1600 Australians may have actually died as a result of this virus. On 23 May 2009 the federal government classified the outbreak as CONTAIN phase except in Victoria where it was escalated to the SUSTAIN phase on 3 June 2009. This gave government authorities permission to close schools in order to slow the spread of the disease. On 17 June 2009 the Department of Health and Ageing introduced a new phase called PROTECT. This modified the response to focus on people with high risk of complications from the disease. Testing at airports was discontinued. The national stockpile of antiviral drugs were no longer made available to people with the flu unless there were more than mild symptoms or a high risk of dying.

Planning and preparing for pandemics has happened in countries and international organizations. The World Health Organization writes recommendations and guidelines,though there is no sustained mechanism to review countries' preparedness for epidemics and their rapid response abilities. National action depends on national governments. In 2005–2006,before the 2009 swine flu pandemic and during the decade following it,the governments in the United States,France,UK,and others managed strategic health equipment stocks,but they often reduced stocks after the 2009 pandemic in order to reduce costs.
