Vaccines are among the most powerful inventions in history, making once-feared diseases preventable,” declared Dr Tedros Adhanom Ghebreyesus, the director-general of the World Health Organization (WHO), in April 2024. The latest figures reveal that vaccines have saved 154 million lives over the past 50 years.
At the same time, sustainability has risen dramatically on the sociopolitical agenda to become an undercurrent to all global development.
This report acknowledges the vital public health role of vaccines while considering their intersection with sustainability. Based on desk research, framework building and expert insights, it addresses what is being done to make vaccine development, procurement and delivery more sustainable.
Global and regional vaccine procurers, known as multilateral procurement organisations, such as the United Nations Children’s Fund (UNICEF) and the Pan American Health Organization (PAHO), are asking what they can do to incentivise and shape sustainable vaccine procurement. With just these two organisations procuring 3.4 billion and 400 million vaccines each year, respectively, their activities can influence the wider vaccine industry.
How vaccines can be sustainably developed, procured and delivered is also being explored by manufacturers.
Key findings from the research include:
- Quality healthcare requires vaccines, but the vaccine lifecycle contributes to greenhouse gas (GHG) emissions and waste.
In most countries, the carbon footprint of the healthcare sector, of which vaccines are a part of, is only exceeded by the energy, transport and construction sectors. The vaccine lifecycle can be broken down into four domains: production and development, transport and distribution, delivery and healthcare systems, and waste and ancillary products. Numerous sustainability and GHG challenges exist in each. Given that reducing vaccine production is not an option due to the public benefits, multilateral organisations, producers, suppliers and other stakeholders are looking closely at the industry for opportunities to improve sustainability.
- As the concept of green vaccine procurement develops, the quality, efficacy, availability, affordability and health security of vaccines remain paramount.
Although environmental considerations are increasingly recognised as important in vaccine decision-making, any improvements to their sustainability require careful consideration so as not to compromise these priorities.
- Multilateral procurement organisations, such as UNICEF and PAHO, hold great power for encouraging industry-wide sustainability changes.
Considering their reach, these organisations could influence other vaccine buyers to adopt more sustainable public procurement practices. They could also prompt vaccine manufacturers to change how they produce GHGs and report emissions. On this point, Luciana Vasconcellos, a procurement professional formerly with PAHO, states that “if multilateral organisations start to put sustainability criteria in their procurement processes, it acts as a major incentive directing their attention towards crucial sustainable practices.”
- Multilateral organisations UNICEF and PAHO are adding sustainability to their vaccine procurement strategies and value statements—which is a promising first step.
While these actions demonstrate progress for the vaccine industry, sustainability procurement remains an early concept. There are no well-defined criteria by which to act and implementation by manufacturers is still voluntary. The two agencies are on par in developing their sustainability goals for greener vaccines. UNICEF is focusing on GHG emissions, energy and water consumption, wastewater, hazardous waste, biodiversity, and packaging. Meanwhile, PAHO has already set targets to reduce GHGs in the supply chain. It is also looking at promoting air to sea transport, reducing packaging and using green shipping lanes.
- Incentives can help businesses along the entire supply chain adopt sustainable practices.
In this heavily regulated industry, change can be risky and costly. Incentives such as legal instruments or environmental weightings in contracts by multilateral organisations are particularly helpful to promote sustainability.
- Innovations around greener vaccine solutions are on the rise, but vaccine producers are at varied stages of their sustainability journey.
Actors along the supply chain are exploring innovative methods to reduce their GHGs and waste, but they vary in their sustainability maturity. Promising solutions include improved vaccine design (such as thermostable vaccines), minimal packaging, renewable energy in production, and less carbon-intensive modes of vaccine transport and delivery.
- Vaccines play a vital role in mitigating climate change and adapting to its impacts.
Effective vaccines can prevent carbon emissions, as treating infectious diseases can be carbon-intensive. As climate change results in diseases sometimes developing in new geographical areas, vaccines are crucial in controlling the effects on public health and on healthcare systems’ emissions.
