No matter how effective vaccines are, they are not enough to control and contain the covid-19 pandemic, according to a report in Scientific American.
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.
