Polio epidemic
A polio vaccine was invented in 1954. Each year after that, the number of polio cases decreased. By 1974, only 5 cases occurred. These were all people who were linked to the polio vaccine.
The first Polio epidemic was in 1894 in Vermont with 132 cases of it.

There are still cases of polio out there today, so we have the vaccinations if someday we were to have another breakout of the epidemic!
Immunization is crucial in combating the polio epidemic as it helps to build herd immunity within communities, significantly reducing the spread of the virus. Vaccines, such as the oral polio vaccine (OPV) and inactivated polio vaccine (IPV), effectively protect individuals from infection and prevent severe disease. Widespread vaccination campaigns can interrupt transmission of the virus, leading to a decline in polio cases and ultimately contributing to the goal of eradicating the disease globally. Additionally, immunization protects vulnerable populations, including those who cannot be vaccinated due to medical reasons, by reducing the overall incidence of polio.
Polio was spread human-to-human, not by a vector.
You can't get polio from kissing. Polio is spread by the oral fecal route.
