You will encounter these characters mostly in and around the medina and along the beach front promenade.tay safe [edit]. Tangier is a relatively safe and peaceful city.

Examples of live (example attenuated) vaccines include: Viral: measles vaccine, mumps vaccine, rubella vaccine, Live attenuated influenza vaccine (the seasonal flu nasal spray and the 2009 H1N1 flu nasal spray), chicken pox vaccine, smallpox vaccine, oral polio vaccine (Sabin), rotavirus vaccine, and yellow fever vaccine.
There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (âwildâ) virus or bacteria in a laboratory.
