When you search for subjects using MeSH terms from the Medline thesaurus you will also have the option of appending subheadings to narrow the focus of your search. For example when you search Measles Vaccine you can choose any, or all, or none, of the subheadings listed below. Deliberate stimulation of the host's immune response.
Active immunization involves administration of antigens or immunologic adjuvants.
Attitude to Health Public attitudes toward health, disease, and the medical care system. The attitude of a significant portion of a population toward any given proposition, based upon a measurable amount of factual evidence, and involving some degree of reflection, analysis, and reasoning. In this search strategy the section in the square brackets after each term includes majr - which focuses the search on articles where the subject is a major issue in the article. The terms viral vaccines or immunization will be combined with either attitude to health, or public opinion, and the search is then limited to articles which are in English. AIDS vaccines are excluded, as they are not needed for this search.
