Vaccination rates are a topic of global concern, with some countries experiencing declines in recent years. While the reasons for this trend vary, the spread of misinformation and shifting views on vaccines, including by prominent officials, have been cited as contributing factors. This has led to outbreaks of preventable diseases, such as measles in the United States, and concerns about the potential for future outbreaks. In addition, the global response to emerging diseases, such as mpox, has been lackluster, with vaccine distribution falling short of promises. These issues highlight the complexities surrounding vaccination policies and their impact on public health.

Low-income countries lag behind in vaccination coverage
While the world has made significant strides in vaccination coverage, disparities persist, with low-income countries lagging behind their higher-income counterparts. As of December 2021, just 3% of low-income countries' populations were fully vaccinated against COVID-19, falling far short of the World Health Organization's target of 40% vaccination coverage by the end of 2021.
Several factors contribute to the vaccination coverage gap between low-income countries and other parts of the world. One critical issue is vaccine stockouts or shortages, which occur due to challenges with supply and logistics. Between 2011 and 2015, an average of 58 countries annually experienced at least one national-level vaccine stockout event, and this number increased to 94 countries between 2015 and 2022. LICs, LMICs, and UMICs are more likely to face these stockout events, impacting their ability to provide consistent vaccination services.
Economic inequalities also play a significant role in vaccination coverage. Countries with higher income levels tend to exhibit higher vaccination coverage rates. This disparity is evident when comparing the coverage of four vaccines in LICs with that of HICs, UMICs, and LMICs. From 2015 to 2021, the gap in vaccination coverage between LICs and higher-income countries widened. However, since 2021, LICs have shown an increasing trend in vaccination coverage, indicating some progress in addressing these inequalities.
Education-related inequalities also influence vaccination coverage, with countries that have higher education attainment levels tending to have lower vaccine confidence. This suggests that misinformation and disinformation can hinder vaccination uptake, as seen in Papua New Guinea, where vaccine hesitancy is fuelled by misinformation on social media. Additionally, healthcare capacity disparities within countries can significantly impact vaccination coverage, as seen in the United States, where rural areas with limited healthcare resources and access have lower vaccination rates.
To address these disparities and improve vaccination coverage in low-income countries, a multifaceted approach is necessary. This includes increasing access to vaccines through creative financial tools, strengthening healthcare infrastructure, particularly in underserved areas, and addressing misinformation and disinformation to increase vaccine confidence and acceptance. While reaching global vaccination targets is challenging, concerted efforts and investments can help achieve these milestones and ensure equitable access to essential vaccines worldwide.

Germany withholds quarantine compensation from voluntarily unvaccinated people
Germany has taken a firm stance against providing quarantine compensation for voluntarily unvaccinated individuals. As of November 1, 2021, German states agreed that unvaccinated employees required to quarantine due to COVID-19 exposure would no longer receive wage compensation. This decision was announced by Germany's Health Minister, Jens Spahn, who emphasized fairness to taxpayers who should not bear the cost of another's choice to remain unvaccinated. This policy change has sparked debates about the implications for workers' finances and public health, with critics arguing it could lead to people choosing work over quarantining.
The German policy specifically targets those who choose not to get vaccinated, with exemptions for those who cannot be vaccinated due to medical reasons or a lack of public vaccination recommendations. This distinction between voluntary and involuntary unvaccinated individuals is crucial in Germany's approach to quarantine compensation. It is important to note that if a voluntarily unvaccinated person is quarantined because they are infected, they will still receive money in lieu of wages for being sick.
Germany's approach to withholding quarantine compensation from the voluntarily unvaccinated is not an isolated case. Other countries have implemented various measures to encourage vaccination. For instance, some countries have introduced fines for parents who refuse to vaccinate their children against measles and other diseases or denied them state benefits. Italy, and possibly other nations, go a step further by prohibiting unvaccinated children from attending state schools.
While these measures aim to promote vaccination, they also raise ethical questions about the balance between individual choice and public health. In Denmark, for example, all vaccines are voluntary, and the country maintains high vaccine uptake rates comparable to the U.S., where vaccinations are often mandatory for school attendance. Greece has also taken a different approach by imposing fines on the non-vaccinated, with Prime Minister Kyriakos Mitsotakis stating that it is "not a punishment."
The varying approaches to vaccination policies worldwide reflect the complexities of addressing public health challenges while respecting individual liberties. Germany's decision to withhold quarantine compensation from voluntarily unvaccinated individuals is a notable strategy within this global context, aiming to incentivize vaccination while also considering the fairness to taxpayers.

Denmark has a minimalist vaccine schedule, targeting only the most severe diseases
Denmark has a notably minimalist vaccine schedule compared to other high-income countries, targeting only 10 diseases, which are deemed the most severe and life-threatening by the nation's health authorities. This is in contrast to the US, which vaccinates against 18 diseases. Denmark's vaccination schedule includes the MMR vaccine, which protects against measles, mumps, and rubella. These diseases can cause severe illness, especially measles, which is highly contagious. Since 2008, Denmark has offered the MMR vaccine to children at 15 months (MMR1) and four years (MMR2).
Denmark's approach to vaccination is characterized by voluntary participation and a high degree of confidence in national authorities. Despite being fully voluntary, Denmark has consistently maintained high rates of vaccine uptake, comparable to those in the US, where vaccinations are required for attendance in public schools. This suggests that Denmark's minimalist vaccine schedule effectively balances individual choice with community benefit.
However, it is important to note that Denmark's success with voluntary vaccination may not be easily replicable in other countries. Anders Hviid, an epidemiologist at the Statens Serum Institut in Copenhagen, cautions against using Denmark as a model for other countries' vaccination policies. Hviid emphasizes the uniqueness of Denmark's situation and healthcare system. Additionally, other Nordic countries with similar characteristics vaccinate their children more frequently and against a broader range of diseases.
Denmark's minimalist vaccine schedule has attracted attention from various officials and researchers, including Christine Stabell Benn, a researcher at the University of Southern Denmark. Benn has dedicated her career to studying vaccine side effects and is skeptical of the notion that more vaccines automatically lead to better health outcomes. She suggests that the US may be "overvaccinating" its children. However, infectious disease physicians like Jake Scott argue that the focus should be on effectively protecting the most vulnerable populations based on overwhelming evidence, rather than solely on the number of vaccines administered.
In summary, Denmark's minimalist vaccine schedule targets the most severe diseases and maintains high vaccine uptake through voluntary participation. While Denmark's approach has sparked interest in other countries, it is essential to consider the unique context of each country's healthcare system and disease burden when formulating vaccination policies.

Italy doesn't allow unvaccinated children to attend state schools
In Italy, unvaccinated children are banned from attending state schools. This law, introduced in 2017, is a result of a surge in measles cases and a decline in children's immunisation rates. The law, known as the Lorenzin law, mandates that children receive various immunisations before enrolling in school, such as chickenpox, polio, measles, mumps, and rubella. Parents who fail to comply with these requirements face fines of up to €500 (£425; $560).
The implementation of the Lorenzin law has been contentious. Initially, a populist government abolished vaccination requirements for children's school attendance, citing concerns about the number of required vaccinations and their potential dangers. However, the subsequent coalition government reversed this decision, reintroducing mandatory immunisations. This change occurred due to accusations of pursuing anti-vaccination policies and the need to increase immunisation rates to achieve herd immunity.
The impact of the law has been positive, according to Italian officials, who report improved vaccination rates since its implementation. The law's supporters argue that it is essential to protect children's health and prevent the spread of vaccine-preventable diseases. On the other hand, critics argue that it infringes on parental choice and personal beliefs about vaccination.
Italy's approach to mandatory vaccination for school attendance is not unique. Several other countries, including France, Germany, the United States, and parts of Australia, have similar requirements. These measures aim to protect public health and ensure that communities achieve herd immunity against dangerous diseases.
The debate around mandatory vaccination highlights the complex interplay between individual rights and public health priorities. While some argue for personal freedom in medical choices, others emphasize the collective responsibility to protect vulnerable community members and maintain high immunisation rates to prevent disease outbreaks. Italy's experience illustrates the challenges faced by governments in balancing these competing interests and maintaining trust in vaccination programmes.

Global coverage for the first dose of HPV vaccine in girls grew from 27% in 2023 to 31% in 2024
There are indeed countries where vaccine uptake is low, and some where it is non-existent. For instance, in 2022, first-dose HPV vaccination coverage among girls aged 9 to 14 in China was only 4%, with full-dose coverage of 0.3%. In Vietnam, as of 2023, only 12% of women and girls aged 15 to 29 received the HPV vaccine.
However, global coverage for the first dose of the HPV vaccine in girls is increasing. It grew from 20% in 2022 to 27% in 2023, and in 2024, 57 countries were implementing the single-dose schedule. The HPV vaccine is on the World Health Organization's List of Essential Medicines, and the WHO has set a global target for 2030 of 90% of girls completing a full HPV vaccination series by age 15.
The primary target group for HPV vaccination is young adolescent girls aged 9–14. The vaccination schedule depends on the age of the recipient, with a one- or two-dose schedule recommended for girls aged 9–14, the same for girls and women aged 15–20, and two doses with a 6-month interval for women older than 21. The HPV vaccine is particularly cost-effective in resource-constrained settings, and it is offered free of charge in some countries, such as Ireland.
Despite the benefits of HPV vaccination, improving coverage has been difficult in some countries, such as Cameroon, where a gender-neutral and single-dose vaccination policy significantly increased adolescent females' first-dose vaccination at regional and national levels.

Frequently asked questions
Yes, some countries, such as Tanzania, Madagascar, Burundi, and Eritrea, have not made plans to vaccinate their populations against COVID-19.
There could be various reasons for this, including a lack of trust in the vaccines due to safety concerns, nationalism, and the influence of anti-vaccine rhetoric from politicians.
When a significant proportion of a population is unvaccinated, there is a higher risk of community spread of diseases such as COVID-19 and measles. This can lead to mutations of the virus, which may render vaccines ineffective.
It is not realistic for vaccinated countries to completely shut their borders from the rest of the world. Interaction between citizens of vaccinated and unvaccinated countries is inevitable, and the best protection is to quickly roll out vaccines and enforce other public health measures.
Governments should work together to scale up vaccine production and supply, address misinformation and hesitancy, and provide incentives for people to get vaccinated, such as the green passport program in Israel.
