Vaccination is a process of making an individual immune against an infection following administration of a substance known as a `vaccine against the disease . It was started towards the end of the 18th century by Edward Jenner who created a vaccine against small pox . Louis Pasteur later invented a vaccine against rabies and anthrax . Vaccination claimed its first amazing success in 1977 , when it was able to eradicate small pox . Many other successes were claimed as vaccination has nearly managed to eradicate several infectious diseases especially in developed

br nations (such as measles , mumps and rubella in the US . However , people have also been considering that vaccination is not safe and efficient Research has however , not been able to prove such issues

Vaccination works by stimulating the immune system . Certain substances present in the vaccine known initiate the immune system to produce antibodies (protective proteins ) against the disease-causing agents These antibodies are able to recognize , capture and destroy the infectious agent when they enter the body and hence prevent the disease The substances present in the vaccines are in fact altered or incomplete forms of the infectious agent and hence will not cause the actual disease

However , as vaccination is being administered to millions of children worldwide annually , instances of adverse-effects do crop up . These adverse-effects may be due to defective production , faulty administration , allergic reactions , autoimmune problems , etc . Minor adverse-effects such as fever , malaise , pain at the injection site , skin rashes , etc , are common , and usually get better within a day or two without any treatment . Major adverse-effects , such as autoimmune diss and neurological symptoms Crohn 's disease and autism (with the MMR vaccine and sudden infant death syndrome , neurological diss and multiple sclerosis (with the hepatitis B vaccine ) may have been reported . However , a number of studies conducted were not able to prove such issues . The vaccine contains very small amounts of a mercury-compound as a preservative . It may not cause any problem considering its minute doses , but recently its quantity has been reduced or eliminated

Some people consider delaying vaccination , especially the hepatitis B vaccine (since hepatitis B is risk only in adolescents and adulthood However , studies have shown that ever since the introduction of vaccination against Hepatitis B , the occurrence of the disease has significantly reduced the infection in infants (it was previously as high as 25 , 000 infants a year . Only redness and pain at the site of administration have been the commonly reported adverse-effect against the vaccine . Delaying vaccination would only increase the risk of being infected with the disease . Hence , to obtain complete benefits of vaccination , the process should be initiated as early as possible in infanthood

Rota-shield was a vaccine produced against a vaccine infection and condition elements of a monkey virus and a human virus . The vaccine was associated with bleeding and intussusception of the intestines and hence had to be withdrawn . Following this incident , the authorities began to closely monitor safety issues of all new vaccines in...
