States with Highest COVID-19 Vaccination Rates Showed Steepest Decline in Pediatric Asthma Prevalence
Study suggests COVID-19 vaccination might have broader benefits for children living with asthma
WILMINGTON, Del. (July 3, 2024) — States with high rates of COVID-19 vaccination saw more pediatric asthma patients get a break from their symptoms, according to new research published today in JAMA Network Open by leaders from Nemours Children’s Health and Endeavor Health.
“Asthma is one of the most common chronic illnesses among children in the United States, with about 4.7 million children experiencing symptoms each year,” said lead author Matthew M. Davis, MD, MAPP, Executive Vice-President, Enterprise Physician-in-Chief and Chief Scientific Officer of Nemours Children’s Health. “Whether asthma is mild or severe, it affects children’s quality of life. So anything we can do to help kids avoid flare-ups is beneficial.”
In the early months of the COVID-19 pandemic in 2020, social distancing and school closures are thought to have resulted in fewer flares of asthma for many pediatric patients. Dr. Davis and coauthor Lakshmi Halasyamani, MD, Chief Clinical Officer of Endeavor Health in Evanston, Illinois, wondered whether that benefit extended into 2021, as the first vaccines against COVID-19 were being widely administered to adults and then children.
In the study, Drs. Davis and Halasyamani compared the change in parent-reported childhood asthma symptoms between 2018-2019 and 2020-2021. They combined that data with state COVID-19 vaccination rates for people ages 5 and up in 2020-2021, as reported by the U.S. Centers for Disease Control and Prevention (CDC).
The researchers found that with each increase of 10 percentage points in COVID-19 vaccination coverage, parent-reported child asthma symptoms decreased by .36 percentage points.
States in the highest quarter of COVID-19 vaccination rates overall had a decrease in asthma symptoms of 1.7 percentage points—an almost 3 times more favorable impact than states in the lowest quarter of COVID-19 vaccination rates overall, which saw an average decrease in asthma symptoms of only 0.6 percentage points in 2020-2021, compared with 2018-2019.
The coauthors explained that several factors could have contributed to the reduction in asthma symptoms. Community-level immunity, also called “herd immunity,” in states with higher vaccination rates may have helped reduce children’s risk of contracting COVID-19 and developing asthma complications. Another possibility is that children living in states with higher COVID-19 vaccination rates may have been more likely to get the shots soon after immunizations were approved for their age groups.
According to the coauthors, these findings also raise the possibility that COVID-19 vaccinations may effectively fight other illnesses that stem from coronaviruses, including the common cold.
“Ongoing vaccination against COVID-19 may offer direct benefits for children with a history of asthma, but this must be confirmed with further research,” said Dr. Halasyamani. “It also raises the question of whether broader population-level COVID-19 vaccination among children and adults can help protect children with asthma, too.”
The coauthors pointed out that one limitation of the study is that it did not measure vaccination rates specifically in children with asthma. In addition, while parent-reported data is considered a meaningful measure of patient experience, additional data such as hospital stays or emergency department visits could be used to verify these findings.

Dexamethasone is one of the most important drugs in the treatment of severe COVID-19, but patients respond very differently to the therapy. Researchers at the German Center for Neurodegenerative Diseases (DZNE) and Charité – Universitätsmedizin Berlin have now discovered how the cortisone compound influences the impaired inflammatory response and which patients benefit from it. Their method uses so-called single-cell analyses and raises hopes for a precise prediction tool for other therapies and diseases as well. The findings have been published in the scientific journal Cell.
It has long been puzzling why certain drugs work so well for some people and fail ...

The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research believed that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, The Hong Kong Polytechnic University (PolyU) researchers have shown that an African plant controls water movement in a previously unknown way – and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical ...

Fukuoka, Japan—The phenomenon known as El Niño can cause abnormal and extreme climate around the world due to it dramatically altering the normal flow of the atmosphere. In Japan, historical data has shown that El Niño years tend to lead to warmer winters. This case was exemplified recently with Japan’s warm 2023-2024 winter season. However, there have also been cases of cold winters in Japan during El Niño years, such as the one recorded in 2014-2015. Yet, it was unclear as to why this was occurring.

Norway wastes huge amounts of energy. Surplus heat produced by industry is hardly exploited at all.
Researchers at the Norwegian University of Science and Technology (NTNU) have been looking at the possibilities for doing something about this.
“Surplus heat from industrial processes is a huge resource,” says Kim Kristiansen.
He has just completed his PhD on a technology that can harness some of the surplus heat that currently goes to waste. Almost all the heat generated by industrial processes is currently released directly into the air or the ocean, and we are not talking about small amounts. In Norway alone, industry produces ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximise their chances of survival, a phenomenon that’s been observed for the first time by researchers at UCL and University Medical Center Utrecht.
The number of genetic mutations in a cancer cell was previously thought to be purely down to chance. But a new study, published in Nature Genetics, has provided insights into how cancers navigate an “evolutionary balancing act”.
The researchers found that mutations in DNA repair genes can be repeatedly created and repaired, acting as ‘genetic switches’ that take the brakes off a tumour’s growth ...

New experimental research shows that the combined effects of ocean warming and acidification could lead to a catastrophic decrease in embryonic shark survival by the year 2100. This research is also the first to demonstrate that monthly temperature variation plays a prominent role in shark embryo mortality.
Oceanic warming and acidification are caused by greater concentrations of CO2 dissolving into marine environments, resulting in rising water temperatures and falling pH levels. “The embryos of egg-laying ...
