Occupational allergies and respiratory health issues are an increasing concern across various industries, significantly impacting worker productivity, well-being and long-term health outcomes. These health problems are primarily triggered by exposure to airborne allergens such as pollen, mold and chemical irritants commonly found in workplace environments. Climate change exacerbates these issues by altering environmental conditions that influence allergen distribution and intensity. Rising temperatures, increased humidity, worsening air pollution and extreme weather events contribute to prolonged pollen seasons, greater mold proliferation, increased volatile organic compound (VOC) emissions and heightened respiratory health risks among workers. VOCs are chemical pollutants emitted from a range of indoor and outdoor sources, further aggravating air quality in workplace environments.

An emerging concern is the relationship between climate change and thunderstorm asthma, a phenomenon where allergens are dispersed during thunderstorms, leading to acute asthma events. Ongoing research continues to examine how environmental changes contribute to the frequency and intensity of asthma-related health issues, particularly in occupational settings.

Both outdoor and indoor workers face distinct challenges due to climate-driven changes in allergen exposure. Agricultural, forestry and construction workers are especially vulnerable to longer pollen seasons and higher concentrations of air pollutants. In contrast, office, healthcare and industrial workers face increased exposure to indoor allergens due to poor ventilation, rising VOC concentrations and other environmental stressors. Low-income workers, older adults and those in developing countries face disproportionate risks due to limited access to healthcare and protective measures.

This viewpoint article explores the relationship between climate change and occupational respiratory allergies, emphasizing the need for effective workplace adaptation strategies such as improving ventilation systems, using air filtration technology and creating allergen-free zones. It also examines the socioeconomic barriers to implementing these measures, mental health impacts of occupational allergies (including stress, anxiety and absenteeism) and the emergence of new allergens due to changing environmental conditions. Furthermore, technological solutions such as AI-driven air quality monitoring systems and wearable sensors hold promise in mitigating allergen exposure by providing real-time data, enabling proactive health measures and supporting policy development to protect worker health. Addressing these challenges is critical to ensuring workers’ health, well-being and productivity in the face of ongoing climate change.

Almost a year after the worldwide appearance of the coronavirus (SARS-CoV-2), several novel vaccines of diverse platforms have been successfully developed and administered. Two mRNA vaccines represented a new type of vaccine that comprised of synthetic mRNA molecules containing the code sequence necessary to build the SARS-CoV-2 spike protein. These mRNA vaccines almost single handedly carried the brunt of the US COVID-19 immunization strategy during the past three years. The known and potential benefits of COVID-19 vaccination outweigh the risks and adverse complications. The ongoing COVID-19 pandemic has stimulated unprecedented research on aspects of the vaccines’ ability to reduce the risk of severe infection and death. Likewise, basic immunological studies are pivotal to unraveling the potential and long-term effects of the vaccines as well as to be able to make adjustments to new vaccine development. As the circulating virus strain continues to evolve, updated vaccines will be critical to protecting the population, particularly the elderly and immune compromised.

Globally, now in the third year of the pandemic, COVID-19 deaths have exceeded more than 6 million. As new subvariants emerge and spread, vaccines work to limit the worst of COVID-19 and continue to be important. Restraints are lifted, and COVID-19 may be seen as done for some, but COVID-19 is not yet done with others, no matter how badly everyone wants it to end. The SARS- CoV-2 pandemic has caused considerable morbidity and mortality worldwide. The protection provided by vaccines and booster doses offer a method of mitigating severe clinical outcomes and mortality. As debates over additional booster shots for COVID-19 intensify, many researchers are looking to the universal coronavirus vaccine model as a guide for managing future variants of SARS-CoV-2 and preempt the next COVID-19 surge.
