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.
The more similar a vaccine is to the disease-causing form of the organism, the better the immune response to the vaccine. The immune response to a live attenuated vaccine is virtually identical to that produced by a natural infection.he more similar a vaccine is to the disease-causing form of the organism, the better the immune response to the vaccine.
