Viral vaccine & it’s effect
Maurice Hilleman discover measle vaccine.
Maurice Hilleman's measles vaccine is estimated to prevent 1 million deaths every year.
A vaccine is a biological preparation that provides active acquired immunity to a particular disease
A vaccine typically contains an agent that resembles a disease-causing microorganism
Vaccine
The agent stimulates the body's immune system to recognize the agent as a threat, destroy it
The administration of vaccines is called vaccination
example, the influenza vaccine,the HPV vaccine, and the chicken pox vaccine.
Vaccine
Viral Vaccine are desingned to treat viral diseases.
These are made up of viruses,These may be dead or alive
Viral vaccine
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.
Effectiveness
Lack of response commonly results from clinical factors such as
Diabetes,Steroid use, HIV infection &Age.
Effectiveness
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.
Effectiveness
immunity might develop too slowly to be effective in time
the antibodies might not disable the pathogen completely
Effectiveness
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.
Adverse effects
Some picture showing the history and way of vaccination and samples of viral vaccines.
Administrtion of vaccine in goat in European countries.
