What is behind COVID, conflictsWe are now in the third year of the COVID-19 pandemic, with the virus still mutating, making it barely possible to foretell when it will end.
As tremendous uncertainty remains and prospects vary greatly across countries, much now depends on the outcome of a race between a mutating virus and the vaccines to end the pandemic, which has led to more than 2 million deaths worldwide, according to Gopinath.
Moreover, global distribution of vaccines is still highly unbalanced and the coronavirus could mutate further in low-income countries where vaccines are not widely available, creating uncertainty for follow-up pandemic prevention and control policies.
