Oral polio vaccine is highly effective and inexpensive (about US$0.10 per dose, or US$0.30 per child and its availability has bolstered efforts to eradicate polio. A study carried out in an isolated Eskimo village showed that antibodies produced from subclinical wild virus infection persisted for at least 40 years. Because the immune response to oral polio vaccine is very similar to natural polio infection, it is expected that oral polio vaccination provides similar lifelong immunity to the virus. Contact immunity to polio can occur when attenuated poliovirus derived from the oral polio vaccine is excreted, and infects and indirectly vaccinates unvaccinated individuals.

Cell technology allows research into a disease to occur at a rapid pace. Cell technology speeds up the production and testing of vaccines and drugs. Cell cultures can produce antibodies in large quantities in a short period of time. Cell cultures allow vaccines to be produced cheaply. Cell cultures make it possible to vaccinate large numbers of people quickly.
The post-eradication era is a period of history for which there has been no precedent whatsoever in terms of a zero base of immunity. Cessation of immunization will eventually create a population susceptible to widespread infection in the event of accidental or intentional reintroduction or re-emergence of the eradicated virus. Thus, even after immunization ceases, vaccine production must continue. However, many currently available vaccines may not be appropriate for continued post-eradication vaccine production or reinstatement. Vaccines must be continually improved and ongoing vaccination research maintained. Other potentially useful antiviral strategies—antivirals, prophylaxis, and probiotics—must also be considered as means to strengthen the immune system and serve as adjuvant or prophylactic therapies. In the case of polio, for example, it remains to be determined which vaccine (oral polio vaccine [OPV] or inactivated polio vaccine [IPV]), or variant thereof, should be produced in the post-eradication, post-vaccination era. A detailed plan for vaccine production will require more information on OPV-derived viral persistence and transmission, as well as continuing dialogue between public health and research communities in order to ensure that appropriate vaccination research continues.
There are various types of cell technology available that can help in the eradication of many harmful diseases. Explanation: This process involves various cell technology that can be helpful when it comes to eradication of disease. There was a very deadly disease named small pox that is completely eradicated because of vaccine. Vaccine can be defined as the group of live or attenuated form of organism that is injected inside the body so that it creates a memory for the future. If the same organism is encountered by the body again then antibodies will be produced very fastly to kill the antigen. There are many more diseases that are kept on focus for its eradication by the help of cell technology.
