  • HPV vaccine


    Human papilloma virus (HPV) vaccines are vaccines that prevent infection by certain types of human papillomavirus. Available vaccines protect against either two, four, or nine types of HPV. All vaccines protect against at least HPV type 16 and 18 that cause the greatest risk of cervical cancer. It is estimated that they may prevent 70% of cervical cancer, 80% of anal cancer, 60% of vaginal cancer, 40% of vulvar cancer, and possibly some mouth cancer. They additionally prevent some genital warts with the vaccines against 4 and 9 HPV types providing greater protection. The World Health Organization (WHO) recommends HPV vaccines as part of routine vaccinations in all countries, along with other prevention measures. The vaccines require two or three doses depending on a person's age and immune status. Vaccinating girls around the ages of nine to thirteen is typically recommended. The vaccines provide protection for at least 5 to 10 years. Cervical cancer screening is still required following vaccination. Vaccinating a large portion of the population may also benefit the unvaccinated. In those already infected the vaccines are not effective. HPV vaccines are very safe. Pain at the site of injection occurs in about 80% of people. Redness and swelling at the site and fever may also occur. No link to Guillain–Barré syndrome has been found. The first HPV vaccine became available in 2006. As of 2017, 71 countries include it in their routine vaccinations, at least for girls. They are on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is about US$47 a dose as of 2014. In the United States it costs more than US$200. Vaccination may be cost effective in the developing world.

  • Health care in the United States


    Health care in the United States is provided by many distinct organizations. Health care facilities are largely owned and operated by private sector businesses. 58% of US community hospitals are non-profit, 21% are government owned, and 21% are for-profit. According to the World Health Organization (WHO), the United States spent more on health care per capita ($9,403), and more on health care as percentage of its GDP (17.1%), than any other nation in 2014. Despite being among the top world economic powers, the US remains the sole industrialized nation in the world without universal health care coverage. In 2013, 64% of health spending was paid for by the government, and funded via programs such as Medicare, Medicaid, the Children's Health Insurance Program, and the Veterans Health Administration. People aged under 65 acquire insurance via their or a family member's employer, by purchasing health insurance on their own, or are uninsured. Health insurance for public sector employees is primarily provided by the government in its role as employer. The United States life expectancy is 78.6 years at birth, up from 75.2 years in 1990; this ranks 42nd among 224 nations, and 22nd out of the 35 industrialized OECD countries, down from 20th in 1990. In 2016 and 2017 life expectancy in the U.S. dropped for the first time since 1993. Of 17 high-income countries studied by the National Institutes of Health, the United States in 2013 had the highest or near-highest prevalence of obesity, car accidents, infant mortality, heart and lung disease, sexually transmitted infections, adolescent pregnancies, injuries, and homicides. A 2014 survey of the healthcare systems of 11 developed countries found that the US healthcare system to be the most expensive and worst-performing in terms of health access, efficiency, and equity. Prohibitively high cost is the primary reason Americans have problems accessing health care. Consulting company Gallup recorded that the uninsured rate among U.S. adults was 11.9% for the first quarter of 2015, continuing the decline of the uninsured rate outset by the Patient Protection and Affordable Care Act (PPACA). At over 27 million, higher than the entire population of Australia, the number of people without health insurance coverage in the United States is one of the primary concerns raised by advocates of health care reform. Lack of health insurance is associated with increased mortality, about sixty thousand preventable deaths per year, depending on the study. A study done at Harvard Medical School with Cambridge Health Alliance showed that nearly 45,000 annual deaths are associated with a lack of patient health insurance. The study also found that uninsured, working Americans have an approximately 40% higher mortality risk compared to privately insured working Americans. In 2010, the Patient Protection and Affordable Care Act (PPACA) became law, enacting major changes in health insurance. The Supreme Court upheld the constitutionality of most of the law in June 2012 and affirmed insurance exchange subsidies in all states in June 2015.

  • Vaccination policy


    Vaccination policy refers to the health policy a government adopts in relation to vaccination. Vaccinations are voluntary in some countries and mandatory in others, as part of their public health system. Some governments pay all or part of the costs of vaccinations in a national vaccination schedule.
