Coronavirus vaccines are rolling out quickly. Here's where the pipeline stands.
Scientists, drugmakers and governments have moved with unprecedented speed to develop multiple vaccines for the new coronavirus.
The fastest of them have proven their vaccines can strongly protect against COVID-19. More than half a dozen shots from developers in the U.S., U.K., Germany, China and Russia have now been cleared by regulators around the world.
Their success is a scientific feat with few parallels. No vaccine has ever been developed so quickly before, never mind readied for widespread use and manufactured at scale.
With the health of their citizens at stake, governments invested enormous sums of money into vaccine research and development, and to prepare to make and distribute the billions of doses necessary to curb the pandemic.
The immunization campaigns that are now underway will help determine whether the virus becomes endemic, recurring year after year, or is ultimately checked. Doses of authorized vaccines remain in short supply worldwide, however, and access has largely been dictated by lucrative deals struck between drugmakers and wealthy countries.
