AJPH Embargoed October Issue

Universal vaccinations can miss seniors, vulnerable people

Even with universal vaccination requirements, measles outbreaks can occur in people at high-risk for the disease, according to a study in the October issue of AJPH. 

In the study, published in the October issue of APHA’s American Journal of Public Health, researchers examined a 2019 measles outbreak in a Singapore residential home for people with intellectual disabilities. The outbreak – which involved 16 residents — was unexpected, as it occurred despite longtime measles vaccination requirements in childhood. Government-ordered vaccinations were implemented in Singapore’s National Childhood Immunization Program in 1975 and made compulsory in 1985. 

The outbreak exposed a gap in delivery and a need for catch-up shots for older and vulnerable populations. Because of limited social interaction, people who lived in the residential home may have had lower measles immunity than the general population, the researchers said. They also may have missed the national vaccination program, or did not attend regular or special education schools where proof of vaccination was required for school registration. 

Researchers noted that screening for immunity to measles and other vaccine-preventable diseases should be considered to prevent outbreaks. 

“There is risk of community introduction of measles to these small pockets of susceptive population, resulting in outbreaks,” the study authors said. “These findings may be applicable to other sheltered or isolated populations, underscoring the special needs of such populations.”

Restricting firearms not significantly linked to homicides by other means

When access to firearms is restricted, there is little evidence that homicides by other means significantly increase, according to a study in AJPH’s October issue. 

As part of a systemic review, researchers analyzed data from 16 studies that provided 60 estimates of the impact of firearm laws on firearm deaths. While strong data was available on the effect on homicides, there was insufficient data on suicides, they said. Based on their findings, the researchers concluded policies that are designed to prevent firearm homicides are likely to have significant benefits for public health. But further studies are needed to determine whether such policies could lead to an overall reduction in suicides. 

“If a gun law prevents 100 firearm homicides, it is expected to prevent 99 total homicides after accounting for possible lethal means substitution, violence contagion and other possible second-order effects,” the study said. 

In 2017, there were more than 47,000 suicides in the U.S., half of which were firearm-related. Another nearly 20,000 people died in homicides, nearly 75% of which were firearm-related.

Commentary: Thanks to partnerships, community intervention on asthma pays off in post-Katrina Louisiana 

Community-based interventions have had positive public health impacts in areas of Lousiana damaged by Hurricane Katrina in 2005, particularly in regard to asthma, according to a commentary in in the October issue of AJPH

Hurricane Katrina devastated communities in the region, killing about 1,800 people. Among its other long-term impacts, flooding left widespread mold in homes and other structures, increasing childhood asthma. The Head-off Environmental Asthma in Louisiana study stepped up to address the issue, using counseling, exposure reduction and other measures to reduce risks for children. The study used a community-based participatory research approach, involving parents, leaders and others closely in its work, which was key to its success. 

After the intervention, participants were more likely to take their prescribed asthma medications, have a provider for follow-up care, experience fewer financial and insurance problems for appointments and have fewer problems obtaining asthma medications, the commentary noted. 

The study illustrated the unique vulnerability of the community, especially with the interconnected threats of historic disparities, persistent environmental health stressors and disasters. It also showed the importance of community involvement. Many study hurdles were overcome by leveraging community resources, such as hiring local staff and heeding the advice of community advisory group members, the authors noted. 

“Drawing on lessons learned through HEAL, post-disaster health studies utilizing a participatory design should also integrate a disaster plan into the study design, incorporate the community’s cultural context, and build on factors influencing community resilience to avoid exacerbating vulnerability,” commentary authors wrote.

Editorial: Protests inspire hope for change 

The COVID-19 pandemic has exposed inequities in U.S. public health and justice systems. But continued demontrations for social justice and evolving political changes show that unjust systems have the potential to be transformed, according to an editorial in the October issue of AJPH

Recent widespread protests that have swept the nation are a way to move public health forward, said author Nancy Krieger, who noted that it is “past time to say ‘enough.’”

COVID-19 inequities reflect the impacts of structural racism that have been in place since the U.S. began as “settler-colonial nation and slave republic,” Krieger noted. Those historic wrongs have echoed across generations, leading to modern-day Black and American Indian people living sicker and shorter lives, even before the pandemic. 

Since the protests spurred by the police killing of Minneapolis resident George Floyd, governments have declared racism a public health crisis, and there is new interest in community investment and safety over police funding, she said. 

“Whether this new awareness translates into meaningful change will depend on sustained mobilization of social movements that recognize both painful histories of past injustice and powerful histories of resistance, thereby inspiring hope for repair and a better equitable and sustainable future,” Krieger noted.
