"RNA sequence"publications that contain the keyword "RNA sequence" as a phrase.
(RNA sequence) -genomePublications that have the keyword "RNA" and "sequence" and do not contain the keyword "genome".
"RNA sequence" -genome -expressionPublications that have the keyword "RNA sequence" and do not contain the keywords "genome" nor "expression".
t:"gene expression"Publications that have the keyword "gene expression" in their title.
t:vaccinePublications that have the keyword "vaccine" in their title.
t:(vaccine efficacy)Publications that have "vaccine" and "efficacy" in their title. It is equivalent to have an AND between them.
