Lack of Vaccine Access Inequality by

Problem Overview

adavis2024_3 — 2025-09-19 23:00:19 UTC

Many low- and middle-income countries (LMICs) still can’t get enough vaccine doses for COVID-19 or key routine vaccines.
Vaccine manufacturing and distribution are heavily concentrated in wealthy countries....

Limited supply & intellectual property/patent issues.
High-income countries are buying far more doses than needed for vaccine hoarding.
Weak health infrastructure (cold storage, transport, staffing) in poorer countries.
Price barriers and lack of economic bargaining power.

Low-income countries in Sub-Saharan Africa, parts of South Asia.
Regions dependent on external manufacturers (African & Eastern Mediterranean often depend heavily on vaccines made outside their regions).
Upper-middle & lower-middle income nations also struggle relative to high-income countries.

High-income countries have purchased enough doses to cover over twice their adult population; LMICs can only cover one-third or less.
In 2021, vaccine supply boomed to ~16 billion doses globally, but low- & middle-income countries often received much less proportionally.
The HPV vaccine has been introduced in just 41% of low-income countries vs 83% in high-income countries though low-income countries carry much of the disease burden.

Delayed recovery from pandemics, more deaths preventable by vaccines.
More variants can emerge if parts of the world stay under-vaccinated.
Deepens health inequities: children miss out on routine immunizations, populations already vulnerable suffer more.
Economic consequences for countries left behind.

WHO — Global Vaccine Market Report & calling for equitable vaccine access. GAVI, The Vaccine Alliance- helps distribute vaccines to poorer countries, supports immunization programs.
COVAX — joint effort by GAVI, WHO, CEPI etc. to ensure LMICs get access to vaccines during pandemics.
