MY SEARCH STRATEGY

1-I phrased my title as a question : Does DNA vaccination induce immunity against toxoplasmosis in murine model
2-I broke it into concepts(pico):
P:Mice
I:DNA vaccine encoding SAG1 antigen
C:The same plasmid without the SAG codon
O:Immunity against toxoplasmosis
3-I searched DNA vaccination and it's synonym DNA immunization with OR program and combined it with toxoplasmosis with AND program.
4-Finally I refined my search results by limiting them by year,publication type(systematic reviews)and language(english)
5-I also used MESH headings while I connected to the internet via ENDNOTE program
