Vaccine hesitancy is a delay in acceptance, or refusal, of vaccines despite the availability of vaccine services and supporting evidence. The term covers refusals to vaccinate, delaying vaccines, accepting vaccines but remaining uncertain about their use, or using certain vaccines but not others. The scientific consensus that vaccines are generally safe and effective is overwhelming. Vaccine hesitancy often results in disease outbreaks and deaths from vaccine-preventable diseases. Therefore, the World Health Organization characterizes vaccine hesitancy as one of the top ten global health threats."Anti-vaccinationism" refers to total opposition to vaccination; in more recent years, anti-vaccinationists have been known as "anti-vaxxers" or "anti-vax". Vaccine hesitancy is complex and context-specific, varying across time, place and vaccines. It can be influenced by factors such as lack of proper scientifically based knowledge and understanding about how vaccines are made or work, as well as psychological factors including fear of needles and distrust of public authorities, a person's lack of confidence (mistrust of the vaccine and/or healthcare provider), complacency (the person does not see a need for the vaccine or does not see the value of the vaccine), and convenience (access to vaccines). It has existed since the invention of vaccination and pre-dates the coining of the terms "vaccine" and "vaccination" by nearly eighty years. The specific hypotheses raised by anti-vaccination advocates have been found to change over time.Although myths, conspiracy theories, misinformation and disinformation spread by the anti-vaccination movement and fringe doctors leads to vaccine hesitancy and public debates around the medical, ethical, and legal issues related to vaccines, there is no serious hesitancy or debate within mainstream medical and scientific circles about the benefits of vaccination.Proposed laws that mandate vaccination, such as California Senate Bill 277 and Australia's No Jab No Pay, have been opposed by anti-vaccination activists and organizations. Opposition to mandatory vaccination may be based on anti-vaccine sentiment, concern that it violates civil liberties or reduces public trust in vaccination, or suspicion of profiteering by the pharmaceutical industry.Wales, measles (2013–)
In 2013, an outbreak of measles occurred in the Welsh city of Swansea. One death was reported. Some estimates indicate that while MMR uptake for two-year-olds was at 94% in Wales in 1995, it had fallen to as low as 67.5% in Swansea by 2003, meaning the region had a "vulnerable" age group. This has been linked to the MMR vaccine controversy, which caused a significant number of parents to fear allowing their children to receive the MMR vaccine. June 5, 2017, saw a new measles outbreak in Wales, at Lliswerry High School in the town of Newport.2019–2020 measles outbreaks
Countermeasures
Vaccine hesitancy is challenging and optimal strategies for approaching it remain uncertain.Multicomponent initiatives which include targeting undervaccinated populations, improving the convenience of and access to vaccines, educational initiatives, and mandates may improve vaccination uptake.The World Health Organization (WHO) published a paper in 2016 intending to aid experts on how to respond to vaccine deniers in public. The WHO recommends for experts to view the general public as their target audience rather than the vaccine denier when debating in a public forum. The WHO also suggests for experts to make unmasking the techniques that the vaccine denier uses to spread misinformation as the goal of the conversation. The WHO asserts that this will make the public audience more resilient against anti-vaccine tactics.Individual liberty
Compulsory vaccination policies have been controversial as long as they have existed, with opponents of mandatory vaccinations arguing that governments should not infringe on an individual's freedom to make medical decisions for themselves or their children, while proponents of compulsory vaccination cite the well-documented public health benefits of vaccination. Others argue that, for compulsory vaccination to effectively prevent disease, there must be not only available vaccines and a population willing to immunize, but also sufficient ability to decline vaccination on grounds of personal belief.Vaccination policy involves complicated ethical issues, as unvaccinated individuals are more likely to contract and spread disease to people with weaker immune systems, such as young children and the elderly, and to other individuals in whom the vaccine has not been effective. However, mandatory vaccination policies raise ethical issues regarding parental rights and informed consent.In the United States, vaccinations are not truly compulsory, but they are typically required in order for children to attend public schools. As of January 2021, five states – Mississippi, West Virginia, California, Maine, and New York – have eliminated religious and philosophical exemptions to required school immunizations.
