WHO and partners have learnt from the mis-steps in the response to the 2009 H1N1 influenza
pandemic
1
and established the Access to COVID-19 Tools (ACT) Accelerator to promote equitable
access to vaccines, therapeutics, and diagnostics.
2
However, many high-income countries already have bilateral agreements with manufacturers
of COVID-19 vaccines.
3
The COVAX Facility of the ACT Accelerator has agreements to access 2 billion doses
of WHO pre-qualified vaccines during 2021, but this represents only 20% of the vaccine
needs of participating countries.
4
Most low-income and middle-income countries (LMICs) face difficulties in accessing
and delivering vaccines and therapeutics for COVID-19 to their populations.
5
COVAX will require decisive action by Gavi, the Vaccine Alliance, WHO, and the Coalition
for Epidemic Preparedness Innovations (CEPI), supported by the countries they serve
and with financing for vaccine purchasing, to ensure people worldwide have equitable
access to COVID-19 vaccines.6, 7, 8
For 80% of the populations in LMICs that will not benefit from COVAX-provided COVID-19
vaccines, finances for purchase or donations are needed. Government measures in response
to COVID-19 and the broader global financial situation have led to increasing fiscal
imbalances of heavily indebted countries.
9
Multinational agencies, financial institutions, and wealthier countries should consider
measures that could provide relief to indebted LMICs. The World Bank, the International
Monetary Fund, and others need to lead an international initiative to mobilise support
for LMICs in need.
Many LMICs do not have an established platform for vaccinating their adult populations.
10
Although it is feasible to deliver COVID-19 vaccines to health-care and other front-line
essential workers, in some LMICs it will be difficult to effectively reach and vaccinate
with two doses all elderly populations and individuals with co-morbidities, given
insufficient mechanisms to identify such groups. Governments and technical leaders
will need to use transparent, accountable, and unbiased processes when they make and
explain evidence-based vaccine prioritisation decisions, while also building confidence
in COVID-19 vaccines and engaging with all the stakeholders.
The ultracold chain requirements of mRNA COVID-19 vaccines are likely to be an insurmountable
hurdle in LMICs, outside of major cities. COVID-19 vaccine delivery will require considerable
investment of resources, health-care staff, and careful planning to avoid opportunity
costs, including a disruption of routine health services and a decline in essential
childhood vaccination coverage, which could result in outbreaks of measles and other
vaccine-preventable diseases. There were more deaths from measles than Ebola virus
disease in 2019 in the aftermath of the Ebola outbreak in the Democratic Republic
of the Congo, due to failure to maintain adequate childhood vaccinations.
11
The infrastructure for vaccination in many LMICs is already inadequate, as shown by
the 19·7 million under-vaccinated infants globally, most of whom are in these countries.
12
Thus, preparation for all aspects of COVID-19 vaccine delivery in LMICs must begin
now with the support of international partners.
Strengthening the capacity of LMICs to do clinical trials and promoting LMIC participation
in research are also crucial.
13
More LMICs need to participate in future vaccine trials and in testing the clinical
effectiveness of different therapeutic agents to ensure that interventions and implementation
are suitable for local contexts.

Since January 2020 Elsevier has created a COVID-19 resource centre with free information
in English and Mandarin on the novel coronavirus COVID-19. The COVID-19 resource centre
is hosted on Elsevier Connect, the company's public news and information website.
Elsevier hereby grants permission to make all its COVID-19-related research that is
available on the COVID-19 resource centre - including this research content - immediately
available in PubMed Central and other publicly funded repositories, such as the WHO
COVID database with rights for unrestricted research re-use and analyses in any form
or by any means with acknowledgement of the original source. These permissions are
granted for free by Elsevier for as long as the COVID-19 resource centre remains active.
Tracking the safety and effectiveness of different COVID-19 vaccines over time in
various populations and settings will necessitate improvements in pharmacovigilance.
14
Regulatory authorities in many LMICs need to be strengthened and could benefit from
a programme of national and international support, as well as regional cooperation
and reliance mechanisms.
15
As part of internationally coordinated actions, COVID-19 technologies should be transferred
to LMIC-based manufacturers, accompanied by regulatory guidance. Efforts to boost
local manufacturing capacity in LMICs will contribute to equity, global solidarity,
and global health security. India and South Africa have called for the suspension
of intellectual property rights related to COVID-19 vaccines to improve access for
LMICs, a move now supported by many other countries, but opposed by the pharmaceutical
industry, which cites the disincentive to innovation.
16
There are further challenges. Governments in LMICs with strong private health sectors,
as those in high-income countries, will need to manage the inherent potential for
inequity, whereby the rich could access COVID-19 vaccines before individuals with
less access to private care who may be at increased risk of severe disease and death,
such as older people and those with comorbidities. LMICs affected by war, civil conflict,
economic crises, or natural disasters, or with large refugee populations or populations
with special needs or vulnerabilities need additional support for vaccines and vaccination
under extremely difficult operational conditions.
Re-examining global governance structures, including the UN and its Security Council,
is much needed so that the voices and interests of billions of people in LMICs are
better represented and recognised. Global support to multilateral institutions is
essential to sustain their support to LMICs to facilitate vaccinations globally. The
COVID-19 pandemic shows that no nation can stand alone. We are all part of a common
humanity that requires us to respect our diverse experiences, cultures, and countries
and forge partnerships that better serve the interests of all.
