Teamwork can help break grip of COVID

Two years into the worst pandemic in a century, it is tempting to think that the world is stuck in a time warp, unable to shake off a virus that has so far killed more than 6 million people and wrecked countless livelihoods. But the truth is that, in the 15 months since the COVID-19 Vaccine Global Access, or COVAX, facility first gained the support of the international community, much has changed.

In September 2020, we did not know whether scientists would be able to develop a safe and effective COVID-19 vaccine. Now we have several. Nor did we know back then that industry would succeed in scaling up production. However, 11 billion vaccine doses were manufactured last year.

Sadly, these successes also serve to highlight where the world has failed in its efforts to combat the pandemic.

Although the world produced enough COVID-19 vaccine doses last year to vaccinate every adult on the planet, more than 3 billion people, most of them living in lower-income countries, have yet to receive their first dose.

High-income countries, meanwhile, have an average vaccination rate of over 75 percent and are now focusing on booster programs. In Africa, by contrast, roughly 10 percent of the population is fully vaccinated, on average, and health systems are still catching up with primary vaccinations.

The recent delivery by COVAX of its 1 billionth COVID-19 vaccine dose represents significant progress toward increasing the supply and ensuring equitable access, thus remedying the current appalling global disparity. This milestone also shows that COVAX－and multilateralism－can work, despite hoarding or restricting of vaccine exports and ingredients by some governments.

Given this momentum, it is essential that COVAX－a partnership of the Coalition for Epidemic Preparedness Innovations, the World Health Organization, UNICEF and Gavi, the Vaccine Alliance－continues to receive the world's backing. Otherwise, as rich countries press ahead with booster rollouts in the face of the Omicron variant, lower-income countries risk falling even further behind.

Such an outcome would constitute not only a moral failure, but also a public-health catastrophe. We all know by now that no one is safe from COVID-19 until everyone is safe. Until we can vaccinate people in all parts of the world, the coronavirus will continue to mutate, resulting in the emergence of new and potentially more dangerous variants. There is a significant risk that we will become trapped in an endless cycle of booster vaccinations, chasing the virus rather than getting ahead of it.

Alternatively, by protecting people everywhere, we can reboot the global economy and fully resume trade, commerce and travel. This will require renewed commitments by high-income countries and vaccine manufacturers to put orders for those most in need first. Providing equitable vaccine access also means ensuring that COVAX has the flexibility to respond to future needs, including those related to booster programs, variant-adapted vaccines or simply additional doses.

Progress in combating the pandemic over the last year has been slower than everyone involved in COVAX wanted and expected, and many lessons need to be learned. And despite the widespread and growing perception that Omicron is somehow less dangerous than previous variants of this coronavirus, we are still in the midst of a global crisis.

But while further supply-side and demand-side challenges will arise this year, we are at last in a position where breaking COVID-19 is a realistic prospect. Speed is of the essence, and the faster we limit the ability of the virus to spread, the sooner we will end the cycles of havoc it has wreaked on our societies and economies. That will require ensuring rapid, fair and equitable access to COVID-19 vaccines to people in all countries.

The delivery of COVAX's 1 billionth dose proves that, when push comes to shove, we can collaborate effectively to tackle massive global challenges. But this achievement is also a timely reminder that much more remains to be done.

COVAX and the other international organizations committed to vaccine equity cannot end the pandemic without the help of governments, industry and civil society. By working together, we have a chance to break the grip of COVID-19 once and for all. We must make the most of it.
