Explore what makes polio so dangerous, what is causing the 21st century resurgence of cases, and how we can eradicate the disease. -- In 1952, polio was everywhere: killing or paralyzing roughly half a million people annually. Yet just 10 years later, paralytic polio cases in the US dropped by 96% and we were on track to get rid of polio for good. But in recent years, the virus started striking back. So, what’s behind these recent spikes Explore the dangers of poliovirus and the possibility of eradicating this deadly disease. Directed by Anton Bogaty.

I wish I could describe to you in one small comment, what it's like to live in the last country where polio still thrives.
I'm talking about Pakistan. It's where I live and have seen growing up that how polio was 99. 99% eradicated from our population only for it to return and now it's spread again and the same cycle continues.
Like the video, the scientific reasons are that the virus mutates and is more damaging if the vaccine or drops aren't given at the right time, similarly it's the blatant ignorance that has gone from bad to worse and is one of the reasons why polio made a comeback.
I wish I was making this up. Polio workers(people employed by our country's health dept to go door to door in neighbourhoods nationwide to give polio drops to kids) have to be protected by police or armed guards because people will shoot at them.
Why Because when you have zero literacy and poor governance for eternity in a country, the local population gets ideas in their heads that these polio drops are a conspiracy by the western nations to make our kids infertile or to make them sick in some way.
I'm sure there are a bajillion other factors involved as to why polio still exists but, trust me, ignorance is also a huge factor as to why polio is still able to survive in 2024.

My grandfather had polio. He was born in 1941 and got it when he was around 7 years old. It left him unable to move one leg. I can only imagine what a boy from one of the poorest parts of Europe, who grew up without a father (who died in 1944) went through. Despite so much hardship he found a good job, a loving wife, and had two sons. He died in 2009, just 9 days after my ninth birthday. Antivaxxers make my blood boil, because I know that had treatment been available, he would not have had to go through anywhere near as many hardships.

At the moment it does not look like we have a viable strategy to eradicate polio like we did smallpox. IPV does not confer gut immunity, which means that vacciknated persons remain susceptible to infection and can be spreaders, but they are protected from myelitis (paralysis)
OTOH, all OPVs revert within days to potentially paralysing virus. Not a problem, as long as vaccination rates are high, but not allowing us to drop populationwide vaccination, ever,

reply

Gotta love how ted ed is too much of a coward to say with their full chest that the rise of polio is because of the Palestinian Genocide thats creating these unsanitary conditions, but no its just vague millitary conflicts in the middle esst.
Liberals love condemning atrocities of the past but sidelining current atrocities as too complicated to understand to seem nuanced & complex. When in reality they're just spineless.

reply

Also a fun little song blip that came from the first polio vaccines. The Sherman brothers, Robert Sherman’s daughter came back from school talking about the vaccine they took at school and how they got a small cube of sage to help take the medicine. That is where the Sherman Brothers got the idea to compose A Spoonful of Sugar for Mary Poppins.
reply

should have also mentioned how the CIA caused the biggest harm to polio eradication efforts in Pakistan by using fake polio vaccine teams to help search for Osama Bin Laden back in 2011. After OBL's assassination, numerous militant groups and radicalized communities have always targeted polio vaccination teams as a revenge.
reply

One thing the video fails to mention about OPV is that it can TRIGGER polio because it is with a weakened live virus. My mum had a colleague from work whose daughter actually got polio because she got too many drops of that vaccine. Yes, it is a highly effective vaccine but also very dangerous if not administered correctly.
reply

No coincidence, I'm sure, but NPR was just talking about the need to get Polio vaccines into Gaza.
Even scarier is the idea that after today (Nov 5th 2024, there could be a brain-worm Airbnb in charge of national health, while turning the entire US into a virtual petri dish for infectious diseases.

reply

It hurts so much that the IOF is actively stopping Palestinian children from receiving the polio vaccines. Children are getting infected again due to food and water scarcity also brought unto them by the IOF.
I am so lucky to live in a first world country fully vaccinated. Every child deserves the same.

reply

Osama was caught by the dr who was administering polio vaccines in the neighbourhood working with the cia, unfortunately Pakistan took the wrong idea and instead not only stop the vaccination but also arrested the doctor for making them lose the world longest hide and seek game. What a world.
reply

And what's even more worse is: as a child, my mom told me that: if a person especially a child doesn't get any treatment if they're suffering from a disease that has the suffix polio in it's name, the person's hands, feet, toes, fingers, legs, and arms will turn backwards permanently
reply

Brazil just switched to injectable polio vaccines to increase efficiency, as fears due to low coverage can bring the virus back.
Thanks to Maga and Bolsonaro's for spreading fakenews about vaccines and lowering our coverage that was, until a couple years ago, pretty good

reply

If we ever invent a time machine, the first thing I'd like to do is to oblige all the anti-vaxers and send them back a couple hundred years to a better time when vaccines did not exist. I'm sure they'd be thrilled. The rest of us will be thrilled too. Everyone's happy.
reply

My dad is only 60 years old and he knows people who are paralyzed due to polio. He knew 3 kids who got put into in iron lungs and and many who died keep in mind this is in rural scotland so imagine the damage it could do in cities. Keep safe. Keep vaccinating
reply

We can thank this in a roundabout way for the ADA. So many people came out severely disabled that they were numerous enough to push for social change. Before that, if you were severely disabled, you were just a sort of family shame.
Progress limps along.

reply

My dad too had polio when he was young, and it left him with an atrophic and smaller left leg. He needs crutches for walking and can't use his left leg at all. I really hope people realise how important it is to keep polio out of the population.
reply

The visuals are nice, but they're missleading. The artist failed to show the vaccines don't _themselves_ fight infection, but cause an inmune reaction which is what fights the virus. A simple explaination to them would have prevented this.
reply

Bill gates created the new polio and created the solution for the new polio (with the small side affect of more surveillance, how convenient. (not saying all Pharma is bad they do amazing stuff too, just a healthy dose of scepticism)
reply

My dad had polio when he was a child. He was lucky, he was only bedridden for a few months and had some sleep issues in the years after.
He has full use of his body and has never needed crutches or an iron lung since.

reply

i still dont get how people dont trust vaccines like yes side effects are expected cause they are a part of a virus but the benefits are soon worldwild and humanity eradicact a lot of pathogens thanks to vaccines
