Вакцины для стареющего населения

СИЭТЛ – Населения в мире все больше – и оно становится все старше. Приближается тот момент, когда пожилых станет больше, чем молодых, – к 2050 году людей в возрасте от 65 лет и старше будет почти в три раза больше, чем в возрасте до четырех лет, – и многие опасаются, что из-за этого нагрузка на государственные бюджеты, системы здравоохранения и экономики станет невыносимой. Но мы можем кое-что сделать, чтобы облегчить это бремя: улучшить здоровье пожилых.

По мере того как мы стареем, наши тела претерпевают сложные изменения, которые, помимо всего прочего, постепенно ослабляют нашу способность реагировать на инфекции и вырабатывать иммунитет (это называется возрастная инволюция иммунитета). Именно поэтому заболевания у пожилых людей, как правило, более серьезны, больше влияют на качество жизни, уровень инвалидности и смертности, чем те же заболевания у более молодых пациентов.

Проще говоря, иммунной системе стареющего организма нужна поддержка. В этом и могут помочь вакцины.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees.
