Stay safe [edit]. Tangier is a relatively safe and peaceful city. The only trouble you may encounter is the persistent touts whom you should ignore, or the con-men ready to overcharge you. 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.
Live attenuated vaccines. Live vaccines are derived from âwild,â or disease-causing, virus or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles vaccine used today was isolated from a child with measles disease in 1954.lthough live attenuated vaccines replicate, they usually do not cause disease, such as may occur with the natural (âwildâ) organism. When a live attenuated vaccine does cause âdisease,â it is usually much milder than the natural disease, and is referred to as an adverse reaction.
