Here is the letter signed by Boris Johnson, Angela Merkel, Emmanuel Macron and other world leaders, in full.
“The Covid-19 pandemic is the biggest challenge to the global community since the 1940s.
“At that time, following the devastation of two world wars, political leaders came together to forge the multilateral system.
“The aims were clear: to bring countries together, to dispel the temptations of isolationism and nationalism, and to address the challenges that could only be achieved together in the spirit of solidarity and co-operation, namely peace, prosperity, health and security.
“Today, we hold the same hope, that as we fight to overcome the Covid-19 pandemic together, we can build a more robust international health architecture that will protect future generations.
“There will be other pandemics and other major health emergencies.
“Together, we must be better prepared to predict, prevent, detect, assess and effectively respond to pandemics in a highly co-ordinated fashion.
“The Covid-19 pandemic has been a stark and painful reminder that nobody is safe until everyone is safe.
“We are, therefore, committed to ensuring universal and equitable access to safe, efficacious and affordable vaccines, medicines and diagnostics for this and future pandemics.
“Immunisation is a global public good and we will need to be able to develop, manufacture and deploy vaccines as quickly as possible.
“This is why the Access to Covid-19 Tools Accelerator (ACT-A) was set up in order to promote equal access to tests, treatments and vaccines and support health systems across the globe.
“ACT-A has delivered on many aspects but equitable access is not achieved yet. There is more we can do to promote global access.
“Such a renewed collective commitment would be a milestone in stepping up pandemic preparedness at the highest political level.
“It would be rooted in the constitution of the World Health Organisation, drawing in other relevant organisations key to this endeavour, in support of the principle of health for all.
“Existing global health instruments, especially the International Health Regulations, would underpin such a treaty, ensuring a firm and tested foundation on which we can build and improve.
“The main goal of this treaty would be to foster an all-of-government and all-of-society approach, strengthening national, regional and global capacities and resilience to future pandemics.
“This includes greatly enhancing international co-operation to improve, for example, alert systems, data-sharing, research, and local, regional and global production and distribution of medical and public health counter measures, such as vaccines, medicines, diagnostics and personal protective equipment.
“And such a treaty should lead to more mutual accountability and shared responsibility, transparency and co-operation within the international system and with its rules and norms.
“To achieve this, we will work with heads of state and governments globally and all stakeholders, including civil society and the private sector.
“We are convinced that it is our responsibility, as leaders of nations and international institutions, to ensure that the world learns the lessons of the Covid-19 pandemic.
“At a time when Covid-19 has exploited our weaknesses and divisions, we must seize this opportunity and come together as a global community for peaceful co-operation that extends beyond this crisis.
“Building our capacities and systems to do this will take time and require a sustained political, financial and societal commitment over many years.
“Pandemic preparedness needs global leadership for a global health system fit for this millennium.
“To make this commitment a reality, we must be guided by solidarity, fairness, transparency, inclusiveness and equity.”
