Primary sources can be reliable, and they can be used. Sometimes, a primary source is even the best possible source, such as when you are supporting a direct quotation. In such cases, the original document is the best source because the original document will be free of any errors or misquotations introduced by subsequent sources.

A primary source is one in which the authors directly participated in the research and documented their personal experiences. They examined the patients, injected the rats, ran the experiments, or supervised those who did. Many papers published in medical journals are primary sources for facts about the research and discoveries made.
Many sources contain a combination of primary/secondary or secondary/tertiary material, sometimes all three. A source that is secondary in one context may be primary in another (e.g. a history book is a secondary source for the facts it reports, but a primary source for what the author wrote about an event).
The best sources in basic science are peer reviewed research articles in reputable journals i.e. primary sources by the WP's definition. The basic science equivalent to secondary sources, i.e. reviews of a developing research field, often just contain a brief summary of the primary research and can be colored by the authors' own view point.
