近年來免疫學的巨大進步使其成為生物科學中發展最快的領域之一。生物化學、遺傳學、分子生物學等其他學科的研究人員的大量涌入，以及越來越多的研究人員通過微生物學和各種醫學學科的更傳統的途徑進入免疫學，促進了這種顯著的增長。因此，免疫學已成為一個廣闊而豐富的領域，涵蓋了從高度臨床到高度分子的觀點。盡管這些觀點可能看起來不同，但實際上它們高度相互依賴。《免疫學評論》對當代免疫學進行了平衡的綜述，并將分子免疫學和免疫生物學結合在一起。

The great advances in immunology in recent years make this field one of the most rapidly growing in biological sciences. This remarkable growth is stimulated by the influx of investigators from other disciplines such as biochemistry, genetics, molecular biology, and by an increased number of investigators who came to immunology through the more traditional routes of microbiology and various medical disciplines. As a consequence, immunology has become a vast and rich field encompassing outlooks that range from the highly clinical to the highly molecular. Although such perspectives may appear diverse, they are, in fact, highly interdependent. Critical Reviews in Immunology presents a balanced overview of contemporary immunology and melds together molecular immunology and immunobiology.
