The big idea: Infectious diseases don't respect borders — an outbreak anywhere can become a pandemic everywhere.
Why disease is a security issue
- This makes disease a global health security threat.
- Like war or terrorism, it endangers whole populations and economies.
The core tension: The core tension of global politics appears in sharp form here — national self-interest vs collective global response. Every country wants to protect its own people first, yet a virus is only beaten when the whole world is protected.
- Borderless — a pathogen spreads through travel and trade, so no country is safe until all are.
- Mass harm — pandemics kill on a huge scale, overwhelm health systems and crash economies.
- Collective-action problem — beating a pandemic needs global cooperation, but each state is tempted to look after itself first.
- Governed by the International Health Regulations — the binding framework for outbreak response.
A virus makes national and global interests collide: Pandemics expose the deepest tension in global politics. Because a pathogen ignores borders, a country's own safety depends on everyone else being protected too — yet the instinct of every government is to secure its own citizens first.
The result: vaccine nationalism
- This produces vaccine nationalism: rich states hoard vaccines and equipment.
- It feels rational nationally but is self-defeating globally.
- Uncontrolled spread anywhere breeds new variants that threaten everyone.
- Health security is the clearest case where going it alone fails — and yet cooperation is hardest exactly when fear is highest.

The COVID-19 pandemic showed all of this at once.
Two things happened together
- Extraordinary scientific cooperation: vaccines were developed at record speed.
- A scramble of national self-interest (border closures, export bans, vaccine hoarding) left poorer countries waiting — and let the virus keep spreading and mutating.
The cooperative response
A pandemic can trigger remarkable global cooperation: scientists share data and genetic sequences across borders, vaccines are developed at record speed through international collaboration, the WHO coordinates guidance and surveillance, and initiatives are set up to try to share vaccines with poorer countries. This is the collective response a borderless threat logically demands — treating the pandemic as a shared security problem to be solved together.
The national self-interest response
But fear pushes states the other way: they close borders, ban exports of vaccines and equipment, and — through vaccine nationalism — buy up far more doses than they need, leaving poorer countries at the back of the queue. Each move looks rational for protecting one's own citizens, but collectively it slows the end of the pandemic, lets the virus keep spreading in unvaccinated populations, and breeds new variants that come back to threaten everyone, including the hoarders.
Case study — COVID-19 and the vaccine nationalism trap: The COVID-19 pandemic was the tension in action.
Cooperation
- Unprecedented cooperation produced effective vaccines in under a year — a triumph of shared science.
Vaccine nationalism
- Richer countries pre-ordered and stockpiled far more doses than their populations needed.
- Many poorer countries could not access vaccines for a long time.
Why it was self-defeating
Rational for each
It felt rational for each rich government protecting its own voters.
Unchecked spread
The virus spread unchecked in under-vaccinated regions.
New variants
New variants emerged that spread back to the wealthy countries, prolonging the crisis for everyone.
No one is safe until everyone is safe.
The lesson: The lesson is stark — against a borderless threat, 'my country first' is not just unfair but ineffective. It captures the HL point: health security is where national self-interest and the collective global response collide most sharply.
The key point: Pandemics are a global security threat because disease is borderless, causes mass harm, and can only be beaten by global cooperation — yet each state is tempted to protect itself first.
What COVID-19 and the rules show
- COVID-19 showed both the cooperative response (shared science, fast vaccines) and vaccine nationalism (hoarding).
- Hoarding is self-defeating because uncontrolled spread breeds variants that threaten everyone.
- The International Health Regulations require detection, reporting and coordination — but enforcing genuine cooperation is the hard part.

Should states put their own people first in a pandemic — or is that both unjust and self-defeating? Can genuine global cooperation overcome the pull of national self-interest? Weigh it — and recommend.
The case for national self-interest
Governments are accountable to their own citizens, not the world, so in a crisis they are expected to protect their own people first — securing vaccines, equipment and borders. Sovereignty means states, not global bodies, decide their response, and there is no world government to compel cooperation. From this angle, 'looking after your own first' is both the legitimate duty of a government and the political reality of a world of sovereign states.
Why national self-interest is self-defeating
But against a borderless pathogen, narrow self-interest backfires: hoarding vaccines while the virus rages elsewhere lets it mutate into variants that evade protection and return to threaten the hoarders. The pandemic only truly ends when it ends everywhere, so cooperation — sharing vaccines, data and capacity — is not just fairer but more effective at protecting each nation's own people. The paradox: the surest way to protect your own is to protect everyone.
One view: own people first
- States must and will put their own people first.
- Governments are accountable to citizens.
- Sovereignty means no one can compel cooperation.
Another view: self-defeating
- 'Nation first' fails against a borderless virus.
- Uncontrolled spread anywhere breeds variants that threaten everyone.
Two perspectives — weigh them: Strong HL answers judge that enlightened self-interest points toward cooperation: protecting your own population ultimately requires protecting everyone's.
So the goal is
- Align the two through binding rules, shared supply and capacity.
- Acknowledge that cooperation is genuinely hard when fear and sovereignty pull states apart.
How pandemics come up in Paper 3: Paper 3 stimulus might show an outbreak, vaccine distribution data, or a cooperation breakdown.

Common mistakes (Paper 3): 1. Treating pandemics as only a medical issue. They're a security and cooperation problem.
2. Missing why hoarding is self-defeating. Variants rebound on everyone.
3. Assuming cooperation is easy. Sovereignty and fear pull states apart.
4. Only describing. Analyse + recommend.
5. Ignoring enforcement. Voluntary sharing collapses under pressure.
