More than 159 million people in 76 countries have received COVID-19 vaccines, with more people being vaccinated each week. But the WHO reported that there are multiple issues threatening to undermine the effort to achieve global herd immunity against COVID-19 — and unless these obstacles are dealt with, the pandemic could go on indefinitely.

Here are three of the biggest threats facing the global vaccination effort:

  1. A Funding Gap: There is currently a $27 billion funding gap for the Access to COVID-19 Tools (ACT) Accelerator, which aims to ensure equitable access to tests, treatments, and vaccines around the world
  2. Vaccine Nationalism: When countries insist on using their leverage and resources to vaccinate their own citizens before other countries receive vaccines: that’s vaccine nationalism.
  3. New COVID-19 Variants: The rapid spread of highly contagious strains further highlights the need for fair vaccine distribution. Otherwise, new and more dangerous mutations could emerge that render existing vaccines ineffective.
