Once scientists choose a type of vaccine to build, they need to decide how to produce the vaccine. Just like any product, the vaccine needs to be assembled in a particular way and made in sufficient quantities so that it can be delivered to the millions of people who need vaccines. The production of vaccines is usually done in a living organism or a group of cells. Because cells contain the cell parts needed to read the DNA instructions and create proteins, they are perfect “factories” to create vaccines.

Collecting Algae for the Lab

Phycologists—not to be confused with psychologists—are scientists who study phytoplankton, or algae. Some phycologists investigate what goes on inside phytoplankton cells. Others are curious about the ecology of algae; that is, they want to know what types of algae live in different places and how they affect the other creatures that live there. Still others are trying to use algae to benefit humans, such as by making algae-based biofuels.
