Measles and herpes viruses establish latent infections inside cells after the initial infection. In this state, they are not circulating in the bloodstream and therefore are not accessible to antibodies. The immune system may still be able to recognize and attack cells harboring the virus through other mechanisms, but antibody-mediated immunity is generally less effective against intracellular pathogens.
