Usage Of Expired Polio Vaccines Creates a Public Scare In China

Regardless of how harsh the punishments will be, what’s more important is no more faulty vaccines used on their children, many parents said.

A recent vaccine scandal in eastern China’s Jiangsu province, where 145 children were confirmed to have received expired polio vaccinations, has once again exposed the country’s poor vaccine management and lack of systematic regulatory oversight, a former Chinese health official said.

To eradicate such lapses, Chen Bingzhong, ex-head of China’s Health Education Research Institute, calls for a nationwide probe, in which, third-party stakeholders such as parents, lawyers or reporters should take part to ensure transparency.

“There should first be a thorough probe into the cause of the Jiangsu case, which serves as another wake-up call. But who should launch the investigation? Local health departments alone won’t work because they are the ones who cause the problem and should be held responsible. An [unbiased] third party has to be involved,” Chen said.

Expired vaccine probe

Jiangsu police, on Monday, began an investigation after the local government in the province’s Jinhu County concluded that “only 145 children” were orally administered with polio vaccines that expired on December 11, 2018.

And so far a total of 17 officials have been punished, including the deputy head of Jinhu County.

The local government has also promised check-ups on all affected children.

Tao Lina, a Shanghai-based vaccine expert, blamed the county’s online registration system, which she said failed to alert doctors about expired vaccines or registered the wrong expiration date, according to a Global Times report.

A cover-up?

But many worried parents are skeptical of the official findings and suspect a larger-scale cover-up.

The case came to light on Jan 7 when a parent — a retired hospital worker — discovered that oral vaccine given to her grandkid was nearly a month out of date, according to local media reports.

Many parents, who picked up the news on social media, followed suit to check batch numbers on their children’s vaccination history and found that expired vaccines include not only polio vaccines, but also diphtheria-tetanus-pertussis (DPT), hepatitis B and varicella.

And the problem dates back to a decade ago, which is further fueling suspicion that the majority of the county’s 20,000 children under the age of 14 may have been exposed to faulty vaccines. The case in Jinhu is the latest in a string of similar scandals in China.

Late last week, hundreds of anxious parents gathered in front of Jinhu government offices, demanding answers.

Violent scuffles

Video footage that has gone viral on the Internet showed repeated scuffles between angry crowds, besieged government officials and squads of mob police, which continued into the night.

Three parents ended up being arrested and local residents have expressed difficulty in uploading videos of the protests to social media.

On Weibo, the equivalent of Twitter in China, some urged parents in Jinhu to stay calm, but many more shared their anger.

“The government’s credibility is overdrawn and the people’s tolerance is being put to the test,” one Weibo user said.

“To be honest, our regulators are all façade with little function,” another complained.

Public outcry

Parents elsewhere complained of governments of all levels’ inaction to address the country’s vaccine problems including appropriate compensations to those who suffer adverse effects.

The Drugs Controller General of India plans to come out with vaccine specific regulatory policy and a manual for regulatory requirements for commercialization of new drug and on how to conduct clinical trials in India, it was announced on Saturday.

A father from Fujian province surnamed Lin told VOA that the local government there has done nothing to help this teenaged son, who experienced severe adverse effects from vaccines at the age of three.

“They [the Fujian government] keep patronizing me and passing the buck,” he said.

“Two to three years ago, my kid was identified to be suffering adverse reactions from vaccines, which is extremely rare. If the government can help deal with it, we have nothing to complain. But it’s been ten years, the government hasn’t even tried to take up a [responsible] stance, which I find very hard to accept. My child is now in a [brain-damaged] state,” he added.

A series of vaccine scandals in China including years of illegal sales of improperly-refrigerated vaccines and locally-produced substandard vaccines, which respectively came to light in March and July last year, have seriously undermined public confidence in spite of repeated calls for tightened regulation.

Vaccine management law

Wang Yuedan, deputy director of Peking University’s immunology department, however, insisted that the Jiangsu case is an isolated misconduct of local medical staff and the upcoming passage of a law on vaccine management will help address regulatory loopholes.

To tighten supervision on vaccines, Beijing released a draft Vaccine Management Law this month and is seeking public opinions until next month.

“I believe, once the law takes effect, there will be harsher punishments [on lawbreakers] to prevent such lapses. Among past expired vaccine cases, the punishment imposed on officials [in Jinhu] this time have been the harshest-ever,” he said.

But Chen disagreed.

He asked why many people from local medical staff to regulators in Jiangsu, who are responsible of tracking vaccine flows, have failed to sound alarm bells over expired vaccines?

That shows a systematic regulatory negligence — serious flaws that legal revisions alone won’t cure if few profit-driven lawbreakers and officials who helped cover up the crisis have been held responsible, he said, adding a nationwide probe will find parents in Jiangsu aren’t alone.

Regardless of how harsh the punishments will be, what’s more important is no more faulty vaccines used on their children, many parents said. (VOA)

Development of Alzheimer’s Disease Not Totally Linked to Genetics: Study

The research team analyzed the gene sequence and the biological age of the body's cells from blood

The colour of our eyes or the straightness of our hair is linked to our DNA, but the development of Alzheimer’s disease isn’t exclusively linked to Genetics, suggest new research.

In the first study published about Alzheimer’s disease among identical triplets, researchers found that despite sharing the same DNA, two of the triplets developed Alzheimer’s while one did not.

The two triplets that developed Alzheimer’s were diagnosed in their mid-70s, said the paper published in the journal Brain.

“These findings show that your genetic code doesn’t dictate whether you are guaranteed to develop Alzheimer’s,” said Dr Morris Freedman, head of neurology at Baycrest Centre for Geriatric Care.

“There is hope for people who have a strong family history of dementia since there are other factors, whether it’s the environment or lifestyle, we don’t know what it is, which could either protect against or accelerate dementia.”

All three, 85-year-old siblings had hypertension, but the two with Alzheimer’s had long-standing, obsessive-compulsive behaviour.

The research team analyzed the gene sequence and the biological age of the body’s cells from blood that was taken from each of the triplets, as well as the children of one of the triplet’s with Alzheimer’s.

Among the children, one developed early onset Alzheimer’s disease at age 50 and the other did not report signs of dementia.

The research team also discovered that although the triplets were octogenarians at the time of the study, the biological age of their cells was six to ten years younger than their chronological age.

In contrast, one of the triplet’s children, who developed early onset Alzheimer’s, had a biological age that was nine years older than the chronological age.

The other child, who did not have dementia, of the same triplet showed a biological age that was close to their actual age.

“The latest genetics research is finding that the DNA we die with isn’t necessarily what we received as a baby, which could relate to why two of the triplets developed Alzheimer’s and one didn’t,” says Dr. Ekaterina Rogaeva, senior author on the paper and researcher at the University of Toronto’s Tanz Centre for Research in Neurodegenerative Diseases.

“As we age, our DNA ages with us and as a result, some cells could mutate and change over time”.
