The influenza vaccine, also known as flu shot, is an annual vaccination using a vaccine that is specific for a given year to protect against the highly variable influenza virus. Each seasonal influenza vaccine contains antigens representing three or four influenza virus strains: one influenza type A subtype H1N1 virus strain, one influenza type A subtype H3N2 virus strain, and either one or two influenza type B virus strains. Influenza vaccines may be administered as an injection or as a nasal spray.
The U.S. Centers for Disease Control and Prevention recommend that everyone over the ages of 6 months should receive the seasonal influenza vaccine. Vaccination campaigns usually focus on people who are at high risk of serious complications

The flu vaccine can also reduce the severity of the flu if a person contracts a strain of the flu that the vaccine did not contain. It takes about two weeks following vaccination for antibodies to protect against the flu.
A 2012 meta analysis found that flu shots were efficacious 67 percent of the time; the populations that benefited the most were HIV-positive adults ages 18 to 55, healthy adults ages 18 to 46 and healthy children ages 6 to 24 months .
Effectiveness
A vaccine is assessed by its efficacy; the extent to which it reduces risk of disease under controlled conditions, and its effectiveness, the observed reduction in risk after the vaccine is put into use. In the case of influenza, effectiveness is expected to be lower than the efficacy because it is measured using the rates of influenza-like illness, which is not always caused by influenza. However, studies on the effectiveness of flu vaccines in the real world are difficult; vaccines may be imperfectly matched, virus prevalence varies widely between years, and influenza is often confused with other influenza-like illnesses. However, in most years, the flu vaccine strains have been a good match for the circulating strains, and even a mis-matched vaccine can often provide

Studies on live vaccines have very limited data, but these preparations may be more effective than inactivated vaccines. The meta-analyses examined the efficacy and effectiveness of inactivated vaccines against seasonal influenza in adults, and the elderly.
A different approach is where Internet content is used to estimate the impact of an influenza vaccination campaign. More specifically, researchers have used data from Twitter and Bing, and proposed a statistical framework which, after a series of operations, maps this information to estimates of the percentage of of influenza-like illness in areas, where vaccinations have been performed. Their impact estimates were in accordance with estimations from Public Health England.
The article’s information is presented with the goal of informing a reader on vaccines. The evidence is statistical and unbiased, showing data on both side effects and disease prevention, providing rates of death and serious illness from both sides. This evidence is sourced from a variety of medical organizations and seems reliable, logical, and easily understood, no language that would inspire an emotional response is used. The validity of studies is not mentioned in the article, but it does encourage readers to investigate further to help make a decision. The article allows a reader to analyze the presented evidence and come to their own

Should the Flu Shot Be Mandatory? Vaccines have been proclaimed by many people as one of the miracles of modern medicine. Vaccines are credited with saving thousands of lives and wiping out many contagious diseases. Recently, there has been a tremendous debate whether annual influenza vaccines should be mandatory. Influenza vaccines should be voluntary because people have the right to examine data on vaccinations and make their own informed decisions.
In 1976, due to an outbreak of influenza at Fort Dix, New Jersey, the United States set a precedent in immunology by attempting to vaccinate the entire population of the country against the possibility of a swine-type Influenza A epidemic. While a great many people were successfully immunized in a very short period of time, the National Influenza Immunization Program (NIIP) quickly became recognized as a failure, one reason being that the feared epidemic never surfaced at all. But this massive undertaking deserves more analysis than just a simple repudiation. For example, all evidence linked to the pathology, microbiology, and historical cycle of influenza and the outbreak at Fort Dix suggests that the reactions of the scientists and other personnel involved in the NIIP were correct. However, one must also acknowledge the many complications and misjudgments that plagued the program after its initiation, from biological difficulties, logistical problems, to tensions with the media. The swine flu is a historical event that needs to be evaluated, regarding both its successes and its failures, so that lessons can be learned for future immunization programs.
Vaccines work. They have kept infants healthy and have saved millions of lives for more than 50 years. Most childhood vaccines are 90% to 99% effective in preventing disease so why would you keep such an advantage away from your child? “ Vaccines are made with a tiny amount of dead or weakened germs. They help the immune system learn how to protect itself against disease. Vaccines are a safe and effective way to keep your child from getting very sick from the real disease.” (healthycanadians.gc.ca).When the word vaccination comes to mind the first thing that should come to our minds is life saving, helpful, and beneficial. Unfortunately not all people would think positively when it comes to vaccinations, they think of the worst that could happen. I understand they want to know the cons to getting the vaccine for their infant, but information can show you that pros outweigh the cons. Vaccinations can not only protect an infant but it goes as far as saving their lives. Society has a strong influence on people 's decisions. In this case society and parental beliefs get in the way of infants well beings.
A vaccine for Hepatitis A has been available in the US since 1996. Commonly children will become immunized between the ages of 12 to 23 months, however an adult can also be vaccinated at any time. Traveling out of the country, using illegal drugs, homosexual men, and anyone who comes in contact with an infected person or animal are recommended to be immunized. The final way hepatitis A can be prevented is with immune globulin.
Influenza is a major public health problem which outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people. In the United States, every year between 5 to 20 percent of the population is affected by influenza. As a result of this, between 3,000 and 49,000 deaths have occurred per year (Biggerstaff et al., 2014). Therefore, the influenza vaccine is the most effective strategy to prevent influenza. This essay will examine two significant reasons for influenza vaccination which are the loss of workforce and economic burden as well as one effect regarding herd immunity.
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)

Vaccines save us from being infected with viruses. They save approximately 2.5 million people from death every year. However, while they help save lives, vaccines still have both minor and severe side effects. This can result in nausea, severe sickness, and in rare cases, death. Every year, 3,000 to 4,500 people in the United States are hospitalized due to vaccine side effects. It is extremely important for all communities to be informed about the side effects of vaccines and what causes them. Also, the Centers for Disease Control and Prevention say that the influenza vaccine is only 48% effective, due to constant mutation of the virus (Scutti, 2017). This means, the influenza vaccine does not work on all
...e flu are very similar to those of the regular flu. However concern arises, because the possibility of the virus creating greater complications is likely. To prevent one from contracting the swine flu, he or she should get vaccinated. The main difference between the regular flu vaccine and the H1N1 flu vaccine is the components of which these vaccines are composed of. One should make the decision to get the swine flu vaccine based on one’s age and current medical condition. It is highly recommended that children and people to the age of twenty-four years-old receive the swine flu vaccine, because they have weaker immunity levels. It is best to ask a doctor which decision is preferred. The goal of health professionals is to eliminate the H1N1 virus as a global health threat, and to allow it to become a mere virus that can be prevented by proper vaccinations.
There is a vaccination against the H1N1 virus that is available by shot or nasal spray. It is recommended that those who are the highest level of risk get the vaccination before it is too late. The vaccine is the best protection against the virus. Side effects of the shot may include soreness, redness, and swelling at injection site, fainting, headaches, fever and nausea. Side effects from the nasal spray include a runny nose, headache, vomiting, aches and a fever. Serious side effects may include difficulty breathing, hives, paleness, weakness, dizziness and a high fever. The vaccines are usually given at the beginning of the flu season to those who aren’t at much risk. But those who are at high risk should get the vaccine yearly.
Research also says that after 5 days the fever and other symptoms have disappeared but a cough and weakness may continue. Usually all symptoms are gone within a week or two. But its important to treat the flu seriously because it can lead to other viruses such as pneumonia and other life-threatening complications. For the most part it appears in infants, senior citizens, and people with long term health problems. People with the flu may not know but they are actually contagious from a day before they feel sick. It would usually be one week for adults and two weeks for young kids.
