new study by researchers at University College London (UCL) and the London School of Hygiene & Tropical Medicine.
In medicine, the hygiene hypothesis states that early childhood exposure to particular microorganisms protects against allergic diseases by contributing to the development of the immune system.
However, there is a pervading view (public narrative) that Western 21st century society is too hygienic, which means toddlers and children are likely to be less exposed to germs in early life and so become less resistant to allergies.
In this paper, published in the
Journal of Allergy and Clinical Immunology, researchers point to four significant reasons that, they say, disprove this theory and conclude we are not too clean for our own good.

It’s a nightmare scenario: A coronavirus variant escapes science’s cleverly constructed defenses and returns to spreading unchecked, sending more than a year’s work to develop and administer billions of vaccine doses up in smoke.
The most recent cause for alarm is the highly infectious Delta variant, first identified in India, which is pushing up case numbers again in countries like the U.K. and Portugal, prompting some EU countries to issue a new round of travel restrictions.
But for now, public health experts say, it s not time to panic.
So far, most argue, the chances of a runaway coronavirus mutation dodging the protective effects of a vaccine known as an escape variant appear slim even though some variants might swerve around immune defenses somewhat.
