Most of the time, polio has no symptoms unless the polio virus gets into the blood.[3] It is uncommon for the virus to enter the brain or spinal cord. If this does happen, it can cause muscles to become paralyzed. Some people get better from the paralysis. Others will be disabled. Depending on which muscles have been affected, these people may need a mobility aid or a wheelchair; they may have difficulty using their hands; or they may even have trouble breathing.
About 15 out of every 10,000 adults who get polio die. (This means an adult has a 0.015% chance of dying from polio.)
Vaccination with polio vaccines could stop the disease all over the world. Organizations like the World Health Organization have been trying to vaccinate as many people as possible against polio.[4] Vaccinations have eliminated polio from most countries in the world.[5][6]
Worldwide, polio has become much less common in the past few decades. In 1988, there were about 350,000 cases of polio in the world. By 2007, the number of cases of polio in the world had decreased by over 99.9%, to just 1,652 cases.[7][8][9]
The disease is preventable with the polio vaccine; however, multiple doses are required for it to be effective. The US Centers for Disease Control and Prevention recommends polio vaccination boosters for travellers and those who live in countries where the disease is endemic.
The way to prevent polio has been known for many years:
Vaccine given 6, 12 and 16 weeks old as part of a six-in-one vaccine.
Three years and four months old as part of a 4-in-one pre-school booster
14 years old as a part of the 3-in-one teenage booster.
The child has to have ALL of these to be fully protected. This explains why polio is still around. In endemic areas, wild polioviruses can infect virtually the entire human population.[10][11] Not all, however, develop paralysis or any other sign of the infection.
The vaccine was developed by Jonas Salk in the 1950s.[12]
↑History is teaching us an important lesson that playing politics with vaccination campaign in the midst of a deadly pandemic is immoral and costs lives. A Step, a 1988 Soviet-Japanese movie directed by Alexander Mitta, is about a struggle to bring a safe and effective Soviet vaccine against polio to Japan in the end of 1950s to help the country fight a deadly outbreak of the disease. The story is very much reminiscent of our effort to bring Sputnik V vaccine to different countries to fight the COVID-19 pandemic in 2021.Pharmaceutical giants with the help from some bureaucrats and biased media put up a resistance to Soviet vaccine imports, maintaining an artificial deficit of polio vaccines in the country in order to protect their monopoly and revenues at the expense of suffering children. Thanks to determination of ordinary Japanese mothers who took to the streets, demanding permission to import the Soviet vaccine and wisdom of honest politicians who cared for their people, the Soviet vaccine finally made its way to Japan. Mass vaccination with the Soviet vaccine started in 1961 and the polio epidemic stopped soon after. We call on politicians, media and regulators not to repeat mistakes from 60 years ago. Examples of Argentina, Hungary, Serbia, San Marino and many other countries where Sputnik V is administered show that using a portfolio of safe and effective vaccines regardless of their origin is the quickest way to defeating the pandemic and saving people’s lives. Thank to cooperation with Russia’s legendary Mosfilm studio the Russian Direct Investment Fund and the Sputnik V team would like to share highlights of this film with its international audience to remind of this great moment in history.
