Hanging vaccine can help protect Alzheimer’s disease
A natural experiment in Wales showed that the sheet vaccine could lower the risk of developing dementia

In 2013, Welsh Public Health Officials fell against Conundrum: new vaccination received to hang, but the supply was not large enough to insert all the elderly in the country. As a repair, the vaccine determines the date of the UTOFFO that was more effective in more than 80 years.
This public health policy unnoticed the real-world experiment, has had the strongest evidence that the strongest evidence has had. Protection effect against Alzheimer’s disease And other forms of dementia. According to the findings published this week Nature, Those who have received vaccination accounted for 20 percent less than seven years to develop dementia compared to those who were uneasily.
“This study shows the causal and protective impact of the prevention or delay of dementia,” says Pascal Geldsetzer, auxiliary teacher at Stanford University and the main author of research. “We’re really looking for, here, in the cause and effect, not only correlation.”

Have been evidence Building years Some viruses can lead to dementia in some cases and vaccination against viruses can reduce this risk. Most of the previous research were made In cells or Laboratory animalsHowever, it was composed of Attorney studies This compared people who wanted to vaccinate with those who did not have in a given population. Observatory studies have basic limits, because researchers cannot easily control other important differences in the level of diet and physical activity, between the two groups.
The “Fine Data” provided by the Welsh Vaccination Program, says, was left, as the only difference between those who did not vaccinate was a small difference when he was born. Birthdays, therefore, were equivalent to a coin flip, random trial used to assign participants to a group or another.
For new research, researchers 80. Birthday fell within a week of vaccine cutting, or it’s just doing it. They received vaccination of almost no birthday before the cutback, and 47% of those who were candidates were chosen to vaccinate.
Researchers compared the health results of both groups in the next seven years to diagnose with dementia that was a total of eight people. Those who received the hanging vaccine, however, were candidates, however, that there were 20% less because they did not receive dementia. Researchers analyzed all other factors, including educational levels, other diseases with other vaccinations or diagnostics, among both teams.
The discoveries suggest that viruses can affect the cases of at least the cases of dementia, as the gem said, and the vaccine can protect against it. Alternatively, some vaccines, such as pendants, is a wider immune system that reduces the risk of developing dementia.
Geldsetzer and his colleagues expect to collect the funds to control these opportunities through a controlled way. If the findings support, the researchers will help researchers better understand researchers who understand Alzheimer’s diseases and other dementia. This would also suggest the vaccines against the sheets and other viral diseases that may be cheap and effective in public health measures to delay or prevent the development of certain people first.
“Direct (swamp) vaccines (swamps) can be a study of the risk of dementia. It adds to the data of that particular vaccine.” It will be important to determine the risk of dementia to determine future research, “Ascherio says.
