‘The Moderna and Pfizer vaccines were developed in record time. However, these announcements highlight significant challenges: delivering two-dose vaccines with stringent cold-chain requirements to almost eight billion people, many of whom reside in communities with underfunded and strained health systems, is no small feat. Even if we address the logistical challenges, the reality is that it takes time and funding to deliver vaccines, treatments and tests that reach everyone in need. It is a sobering reminder that when lifesaving antiretrovirals were introduced for HIV-positive people, it took seven years before the medicine reached the poorest communities. And during that time, millions of people died, and millions more were infected, and the HIV pandemic continued to grow.
‘Until we can overcome these obstacles and ensure equitable delivery of vaccines and treatments once available across the globe, the fundamentals of controlling this virus remain as important as ever.
‘For a long time, many countries will continue to rely on already proven tools to control the pandemic. The formula is simple: test, trace and isolate. This straightforward but effective process is key to safely reopening economies and societies. It is made possible through the rapid and equitable scale-up of diagnostics, which have proven to be the most important tool for limiting the spread of COVID-19. Test, trace and isolate—and ultimately test, trace and treat once more treatments become available—is an efficient, sustainable way to control the virus, especially in contrast to last-resort emergency lockdown measures, which can erode the public support and trust necessary for the success of many other helpful public health measures, including vaccination and mask-wearing.
‘We have seen this strategy implemented successfully around the world for decades with age-old diseases like tuberculosis. This strategy is also making a difference in the fight against COVID-19.’
