Overcoming inhibition of antibody responses to a malaria recombinant vaccinia virus caused by prior exposure to wild type virus

Abstract

Pre-injection of mice with vaccinia virus inhibited the subsequent antibody response to a recombinant polypeptide expressed by vaccinia virus. The inhibition was overcome following additional challenges with recombinant vaccinia virus. This suggests that a potential disadvantage in vaccinia-immune individuals can be circumvented and may be outweighed by the advantages of the vector. © 1991.
