A vaccine is a biological preparation that provides active acquired immunity to a particular diseasedisease A vaccine typically contains an agent that resembles a disease-causing microorganism

The agent stimulates the body's immune system to recognize the agent as a threat, destroy itimmune system The administration of vaccines is called vaccinationvaccination example, the influenza vaccine,the HPV vaccine, and the chicken pox vaccine.influenza vaccineHPV vaccinechicken pox vaccine

Viral Vaccine are desingned to treat viral diseases. These are made up of viruses,These may be dead or alive

Inactivated or killed viral vaccines contain viruses, which have lost their ability to replicate. In order for it to bring about a response it contains more antigen than live vaccines.

Attenuated or live vaccines contain the live form of the virus. These viruses are not pathogenic but are able to induce an immune response

Vaccines have historically been the most effective means to fight and eradicate infectious diseases. Sometimes, protection fails because the host's immune system simply does not respond adequately or at all.

Lack of response commonly results from clinical factors such as Diabetes, Steroid use, HIV infection & Age.

However it also might fail for genetic reasons if the host's immune system includes no strains of, B cells that can generate antibodies suited to reacting effectively and binding to the antigens associated with the pathogen.B cellsantibodiesantigenspathogen

immunity might develop too slowly to be effective in time the antibodies might not disable the pathogen completely

Vaccination given during childhood is generally safe Some potential side effects include: fever, pain around the injection site, and muscle aches. Severe side effects are extremely rare.

Some picture showing the history and way of vaccination and samples of viral vaccines.
