According to a recent analysis from CARE, for every $1 a country spends on Covid-19 vaccine doses, $5 is needed for delivery. Even after receiving vaccine shipments, many COVAX countries still must tackle the challenges of running an effective vaccination campaign. Per an NPR report, these challenges include cold chain storage, healthcare infrastructure and training of healthcare workers, combating vaccine hesitancy and misinformation, and other geographical and political obstacles.
