Why should you get vaccinated?

Vaccines provide a long-term, or even lifelong, protection or immunity to infectious diseases. By vaccination, immunity is achieved with symptoms considerably milder than those suffered when contracting the actual, sometimes very severe, disease. 
Vaccines can be given as injections, nasal sprays, or orally. New dosage forms are being developed.
Vaccines contain weakened or killed pathogens or parts of them and, in many cases, an adjuvant. They stimulate the cells of our immune system to act against that specific infectious agent. 
Vaccines prevent infectious diseases in a natural way, since they teach our own body to produce a protective immune response. Prevention is an effective health care approach for individual and community alike.
