Vaccines Need Equality: Closing the Gender Gap in Immunization

28 April 2026

 

“Immunization is among the smartest investments a society can make, but only when women and girls can access them equally.” Dr. Magda Robalo, Executive Director, Women in Global Health

Vaccines are one of the most powerful public health tools ever developed, saving more than 154 million lives over the past fifty years, the vast majority among children under five. Yet millions of children remain under-vaccinated or entirely unvaccinated, while adults and adolescents continue to miss life-saving vaccines across the life course. Reaching those left behind requires more than supply chains and financing. It requires confronting one of the most overlooked barriers in immunization: gender inequality. 

Too often, immunization is treated as gender-neutral. But vaccines are delivered through health systems shaped by power, gender norms, and unequal access to resources. Gender affects immunization on both the demand side, whether people can seek services, and the supply side, how services are staffed, designed, and delivered. 

When gender barriers are ignored, vaccine coverage stalls. When they are addressed, immunization systems become stronger, fairer, and more effective.

Gender Shapes Who Gets Vaccinated

In many countries, women are the primary caregivers responsible for bringing children to clinics. Yet they may not control household finances, transportation, or final health care decisions. A mother may know her child needs vaccines but lack the money for transport, permission to travel, or time to wait for hours at a facility.

Across 29 country studies supported by UNICEF, common barriers include women’s restricted mobility, limited decision-making power, unpaid care work, and lack of access to accurate vaccine information. These constraints directly affect whether children receive routine immunization on time. 

This means that children’s vaccination status is often tied not only to health system performance but also to women’s autonomy.

Health Systems Also Reproduce Gender Inequality

Gender barriers do not stop at the home. They also exist inside clinics and health systems.

Women may face disrespectful treatment, stigma, or unsafe facilities. In some settings, gender norms mean women are reluctant to seek care if only male vaccinators are available. Long waiting times and inflexible clinic hours disproportionately burden women balancing paid work and unpaid care responsibilities.

At the same time, the health workforce itself is highly gendered. Women make up the majority of frontline health and care workers globally, yet remain underrepresented in leadership and decision-making roles. Those delivering vaccines are often not those shaping vaccine policy. When women are absent from leadership, service design may fail to reflect the realities women face as caregivers, workers, and users of care.

The Hidden Barrier: Data Blindness

One of the biggest obstacles to vaccine equity is the failure to measure gender barriers.

Many countries still do not consistently use sex- and gender-disaggregated data or conduct gender analysis in immunization planning, outputs, and outcomes. Without data, policymakers cannot see where girls, boys, women, men, or marginalized groups are being left behind.

As global health endeavors have repeatedly shown, what is not measured is rarely funded or fixed.

Better data can reveal whether outreach strategies miss women and children in remote areas, whether adolescent girls face stigma around Human Papilloma Virus (HPV) vaccination, or whether male caregivers feel excluded from child immunization services.

Why This Matters Across the Life Course

Gender and vaccines are not only about childhood immunization.

Adolescent girls may face myths and stigma around HPV vaccines. Pregnant women may be excluded from vaccine research or receive inconsistent guidance during outbreaks. Older women may experience lower access to adult vaccination if mobility, income, or caregiving duties limit clinic attendance.

A life-course approach to immunization must, therefore, recognize that gender barriers change over time but persist at every stage.

Five Priorities for Gender-Responsive Immunization

1. Embed gender equality in immunization policy, programming, and financing. Governments should integrate gender analysis into national immunization strategies, budgets, and accountability systems so that barriers facing women and girls are systematically addressed.
2. Fix the data gap. All immunization data should be routinely disaggregated by sex and gender, age, geography, disability, and other relevant factors to reveal who is being missed and why.
3. Design services around women’s lived realities. Vaccination programs must reflect the everyday constraints women face by offering flexible hours, safe and accessible facilities, outreach clinics, childcare support, and respectful care.
4. Put women in decision-making roles. Women should be equally represented in immunization leadership, from local health committees to ministries of health and global governance bodies, so policies reflect lived realities and frontline experience.
5. Engage whole communities in vaccine decisions. Communication strategies should involve both women and men, recognizing that fathers, partners, elders, and community leaders often influence whether vaccines are accepted and accessed.

Vaccines Need Equality to Reach Everyone

Vaccines do not fail because science has failed. They fail when systems cannot reach people fairly.

If a mother cannot leave home safely, if a girl fears stigma, if a health worker faces harassment, or if policymakers ignore gendered barriers, vaccine equity remains out of reach.

World Immunization Week is a reminder that vaccines save lives. But to protect everyone, immunization systems must also confront inequality. Closing the gender gap in vaccination is not an optional add-on to coverage goals; it is central to achieving them.
