Immune Memory After Papillomavirus Vaccination (IMAP-1)
July 20, 2015 updated by: Mark Mulligan, Emory University
Immune Memory After Papillomavirus Vaccination (IMAP-I) Study . DMID 10-0014
Vaccines for human papillomavirus (HPV) have been available in the United States since 2006.
Early studies have shown a high rate of effectiveness of these vaccines, however it is not known how long this protection will last.
The IMAP study will look at various parts of the immune system and potential markers for long lived immune responses to this vaccine.
