A Mother-and-Daughter Team Have Developed What May Be the World’s First Alzheimer’s Vaccine
Alzheimer's is a terrible disease that robs a person of their personality and memory before eventually leading to death. It's the sixth-largest killer in the U.S. and, currently, there are 5.8 million Americans living with the disease.
Wang's vaccine is a significant improvement over previous attempts because it can attack the Alzheimer's protein without creating any adverse side effects.
It devastates people and families and it's estimated that Alzheimer's and other forms of dementia will cost the U.S. $290 billion dollars this year alone. It's estimated that it will become a trillion-dollar-a-year disease by 2050.
There have been over 200 unsuccessful attempts to find a cure for the disease and the clinical trial termination rate is 98 percent.
Alzheimer's is caused by plaque deposits that develop in brain tissue that become toxic to brain cells. One of the major hurdles to finding a cure for the disease is that it's impossible to clear out the deposits from the tissue. So scientists have turned their attention to early detection and prevention.
One very encouraging development has come out of the work done by Dr. Chang Yi Wang, PhD. Wang is a prolific bio-inventor; one of her biggest successes is developing a foot-and-mouth vaccine for pigs that has been administered more than three billion times.

In January, United Neuroscience, a biotech company founded by Yi, her daughter Mei Mei Hu, and son-in-law, Louis Reese, announced the first results from a phase IIa clinical trial on UB-311, an Alzheimer's vaccine.
The vaccine has synthetic versions of amino acid chains that trigger antibodies to attack Alzheimer's protein the blood. Wang's vaccine is a significant improvement over previous attempts because it can attack the Alzheimer's protein without creating any adverse side effects.
"We were able to generate some antibodies in all patients, which is unusual for vaccines," Yi told Wired. "We're talking about almost a 100 percent response rate. So far, we have seen an improvement in three out of three measurements of cognitive performance for patients with mild Alzheimer's disease."
The researchers also claim it can delay the onset of the disease by five years. While this would be a godsend for people with the disease and their families, according to Elle, it could also save Medicare and Medicaid more than $220 billion.
"You'd want to see larger numbers, but this looks like a beneficial treatment," James Brown, director of the Aston University Research Centre for Healthy Ageing, told Wired. "This looks like a silver bullet that can arrest or improve symptoms and, if it passes the next phase, it could be the best chance we've got."
"A word of caution is that it's a small study," says Drew Holzapfel, acting president of the nonprofit UsAgainstAlzheimer's, said according to Elle. "But the initial data is compelling."
The company is now working on its next clinical trial of the vaccine and while hopes are high, so is the pressure. The company has already invested $100 million developing its vaccine platform. According to Reese, the company's ultimate goal is to create a host of vaccines that will be administered to protect people from chronic illness.
"We have a 50-year vision -- to immuno-sculpt people against chronic illness and chronic aging with vaccines as prolific as vaccines for infectious diseases," he told Elle.

Here's how one doctor overcame extraordinary odds to help create the birth control pill
Dr. Percy Julian had so many personal and professional obstacles throughout his life, it’s amazing he was able to accomplish anything at all. But this hidden figure not only overcame these incredible obstacles, he also laid the foundation for the creation of the birth control pill.
Julian’s first obstacle was growing up in the Jim Crow-era south in the early part of the twentieth century, where racial segregation kept many African-Americans out of schools, libraries, parks, restaurants, and more. Despite limited opportunities and education, Julian was accepted to DePauw University in Indiana, where he majored in chemistry. But in college, Julian encountered another obstacle: he wasn’t allowed to stay in DePauw’s student housing because of segregation. Julian found lodging in an off-campus boarding house that refused to serve him meals. To pay for his room, board, and food, Julian waited tables and fired furnaces while he studied chemistry full-time. Incredibly, he graduated in 1920 as valedictorian of his class.
After graduation, Julian landed a fellowship at Harvard University to study chemistry—but here, Julian ran into yet another obstacle. Harvard thought that white students would resent being taught by Julian, an African-American man, so they withdrew his teaching assistantship. Julian instead decided to complete his PhD at the University of Vienna in Austria. When he did, he became one of the first African Americans to ever receive a PhD in chemistry.
Julian received offers for professorships, fellowships, and jobs throughout the 1930s, due to his impressive qualifications—but these offers were almost always revoked when schools or potential employers found out Julian was black. In one instance, Julian was offered a job at the Institute of Paper Chemistory in Appleton, Wisconsin—but Appleton, like many cities in the United States at the time, was known as a “sundown town,” which meant that black people weren’t allowed to be there after dark. As a result, Julian lost the job.
During this time, Julian became an expert at synthesis, which is the process of turning one substance into another through a series of planned chemical reactions. Julian synthesized a plant compound called physostigmine, which would later become a treatment for an eye disease called glaucoma.
In 1936, Julian was finally able to land—and keep—a job at Glidden, and there he found a way to extract soybean protein. This was used to produce a fire-retardant foam used in fire extinguishers to smother oil and gasoline fires aboard ships and aircraft carriers, and it ended up saving the lives of thousands of soldiers during World War II.
At Glidden, Julian found a way to synthesize human sex hormones such as progesterone, estrogen, and testosterone, from plants. This was a hugely profitable discovery for his company—but it also meant that clinicians now had huge quantities of these hormones, making hormone therapy cheaper and easier to come by. His work also laid the foundation for the creation of hormonal birth control: Without the ability to synthesize these hormones, hormonal birth control would not exist.
Julian left Glidden in the 1950s and formed his own company, called Julian Laboratories, outside of Chicago, where he manufactured steroids and conducted his own research. The company turned profitable within a year, but even so Julian’s obstacles weren’t over. In 1950 and 1951, Julian’s home was firebombed and attacked with dynamite, with his family inside. Julian often had to sit out on the front porch of his home with a shotgun to protect his family from violence.
But despite years of racism and violence, Julian’s story has a happy ending. Julian’s family was eventually welcomed into the neighborhood and protected from future attacks (Julian’s daughter lives there to this day). Julian then became one of the country’s first black millionaires when he sold his company in the 1960s.
When Julian passed away at the age of 76, he had more than 130 chemical patents to his name and left behind a body of work that benefits people to this day.
Therapies for Healthy Aging with Dr. Alexandra Bause
My guest today is Dr. Alexandra Bause, a biologist who has dedicated her career to advancing health, medicine and healthier human lifespans. Dr. Bause co-founded a company called Apollo Health Ventures in 2017. Currently a venture partner at Apollo, she's immersed in the discoveries underway in Apollo’s Venture Lab while the company focuses on assembling a team of investors to support progress. Dr. Bause and Apollo Health Ventures say that biotech is at “an inflection point” and is set to become a driver of important change and economic value.
Previously, Dr. Bause worked at the Boston Consulting Group in its healthcare practice specializing in biopharma strategy, among other priorities
She did her PhD studies at Harvard Medical School focusing on molecular mechanisms that contribute to cellular aging, and she’s also a trained pharmacist
In the episode, we talk about the present and future of therapeutics that could increase people’s spans of health, the benefits of certain lifestyle practice, the best use of electronic wearables for these purposes, and much more.
Dr. Bause is at the forefront of developing interventions that target the aging process with the aim of ensuring that all of us can have healthier, more productive lifespans.
