Newswise — The United States Food and Drug Administration (FDA) issued an Emergency Use Authorization (EUA), which was immediately endorsed by the U.S. Centers for Disease Control and Prevention (CDC), for new booster shots created to combat the most recent and highly prevalent omicron variants of COVID-19, specifically BA.4 and BA.5. Fortunately, these most recent and very highly prevalent variants, while more communicable, are less lethal.
In a commentary published in The American Journal of Medicine, researchers from Florida Atlantic University’s Schmidt College of Medicine and collaborators, provide the most updated guidance to health care providers and urge how widespread vaccination with these boosters can now avoid the specter of future and more lethal variants becoming a reality.
“Of the 10 richest countries in the world, the U.S. ranks last in vaccination rates and first in both numbers and rates of COVID-19 deaths,” said Charles H. Hennekens, M.D., Dr.PH, senior author, first Sir Richard Doll Professor of Medicine and senior academic advisor, FAU Schmidt College of Medicine. “The dedicated health care professionals in communities and hospitals across the nation continue to try to address existing and new challenges of COVID-19. We must redouble our efforts to promote evidence-based clinical and public health practices, which should include vaccination of all U.S. adults and eligible children based on the most recent FDA and CDC guidance.”
The authors point out that, compared with influenza, the mortality rate from COVID-19 is about 30 times higher. Further, a positive COVID-19 patient is likely to transmit to about six people compared with one or two for influenza. Finally, the boosters will reduce the risk of dying and hospitalization by more than 90 percent.
“The most simple and straightforward newest guidance we can now offer to health care providers is that all individuals ages 5 and older should receive a booster shot,” said Alexandra Rubenstein, first author, clinical research coordinator, Department of Neurology, Boston Medical Center, and an aspiring physician. “Specifically, based on the recent EUAs issued by the FDA and CDC, those 5 and older may receive Pfizer bivalent boosters, and those ages 6 and older may receive bivalent boosters from Moderna. While the absolute risks of severe COVID-19 are low in youths, the benefit-to-risk ratio was deemed to be favorable in a 13-to-1 vote of independent external advisers to the FDA.”
According to the authors, vaccines to prevent common and serious infectious diseases have had a greater impact on improving human health than any other medical advance of the 20th century. Nonetheless, since 2019, the percentages of children in the U.S. vaccinated against common and serious childhood diseases has decreased.
“In the U.S., diphtheria-pertussis-tetanus or DPT immunizations have decreased from 85 percent in 2019 to 67 percent in 2021,” said co-author Sarah K. Wood, M.D., professor of pediatrics and interim chair, Department of Women’s and Children’s Health and vice dean for medical education, FAU Schmidt College of Medicine. “Recently, a young adult unvaccinated against polio in a neighborhood in Rockland County, New York, contracted a paralytic disease raising concerns that the loss of herd immunity may portend new epidemics of avoidable serious morbidity and mortality in the U.S. and worldwide.”
Ironically, the authors note, virtually all Americans would seek effective and safe therapies for any communicable diseases. Most individuals routinely accept major surgery, toxic chemotherapy and/or radiation therapy for cancer, which result in a far greater number of side effects than are caused by vaccinations. The authors encourage health care providers to recommend a COVID-19 booster vaccine to all eligible patients to protect individuals and communities.

Disease forecasts are like weather forecasts: We cannot predict the finer details of a particular outbreak or a particular storm, but we can often identify when these threats are emerging and prepare accordingly.
The viruses that cause avian influenza are potential threats to global health. Recent animal outbreaks from a subtype called H5N1 have been especially troubling to scientists. Although human infections from H5N1 have been relatively rare, there have been a little more than 900 known cases globally since 2003 – nearly 50% of these cases have been fatal – a mortality rate about 20 times higher than that of the 1918 flu pandemic. If the worst of these rare infections ever became common among people, the results could be devastating.
Approaching potential disease threats from an anthropological perspective, my colleagues and I recently published a book called “Emerging Infections: Three Epidemiological Transitions from Prehistory to the Present” to examine the ways human behaviors have shaped the evolution of infectious diseases, beginning with their first major emergence in the Neolithic period and continuing for 10,000 years to the present day.
Viewed from this deep time perspective, it becomes evident that H5N1 is displaying a common pattern of stepwise invasion from animal to human populations. Like many emerging viruses, H5N1 is making incremental evolutionary changes that could allow it to transmit between people. The periods between these evolutionary steps present opportunities to slow this process and possibly avert a global disaster.
Spillover and viral chatter
When a disease-causing pathogen such as a flu virus is already adapted to infect a particular animal species, it may eventually evolve the ability to infect a new species, such as humans, through a process called spillover.
Spillover is a tricky enterprise. To be successful, the pathogen must have the right set of molecular “keys” compatible with the host’s molecular “locks” so it can break in and out of host cells and hijack their replication machinery. Because these locks often vary between species, the pathogen may have to try many different keys before it can infect an entirely new host species. For instance, the keys a virus successfully uses to infect chickens and ducks may not work on cattle and humans. And because new keys can be made only through random mutation, the odds of obtaining all the right ones are very slim.
Given these evolutionary challenges, it is not surprising that pathogens often get stuck partway into the spillover process. A new variant of the pathogen might be transmissible from an animal only to a person who is either more susceptible due to preexisting illness or more likely to be infected because of extended exposure to the pathogen.
Even then, the pathogen might not be able to break out of its human host and transmit to another person. This is the current situation with H5N1. For the past year, there have been many animal outbreaks in a variety of wild and domestic animals, especially among birds and cattle. But there have also been a small number of human cases, most of which have occurred among poultry and dairy workers who worked closely with large numbers of infected animals.
Pathogen transmission can be modeled in three stages. In Stage 1, the pathogen can be transmitted only between nonhuman animals. In stage 2, the pathogen can also be transmitted to humans, but it is not yet adapted for human-to-human transmission. In Stage 3, the pathogen is fully capable of human-to-human transmission.Ron Barrett, CC BY-SA
Epidemiologists call this situation viral chatter: when human infections occur only in small, sporadic outbreaks that appear like the chattering signals of coded radio communications – tiny bursts of unclear information that may add up to a very ominous message. In the case of viral chatter, the message would be a human pandemic.
Sporadic, individual cases of H5N1 among people suggest that human-to-human transmission may likely occur at some point. But even so, no one knows how long or how many steps it would take for this to happen.
Influenza viruses evolve rapidly. This is partly because two or more flu varieties can infect the same host simultaneously, allowing them to reshuffle their genetic material with one another to produce entirely new varieties.
Genetic reshuffling – aka antigenic shift – between a highly pathogenic strain of avian influenza and a strain of human influenza could create a new strain that’s even more infectious among people.Eunsun Yoo/Biomolecules & Therapeutics, CC BY-NC
These reshuffling events are more likely to occur when there is a diverse range of host species. So it is particularly concerning that H5N1 is known to have infected at least 450 different animal species. It may not be long before the viral chatter gives way to larger human epidemics.
Reshaping the trajectory
The good news is that people can take basic measures to slow down the evolution of H5N1 and potentially reduce the lethality of avian influenza should it ever become a common human infection. But governments and businesses will need to act.
People can start by taking better care of food animals. The total weight of the world’s poultry is greater than all wild bird species combined. So it is not surprising that the geography of most H5N1 outbreaks track more closely with large-scale housing and international transfers of live poultry than with the nesting and migration patterns of wild aquatic birds. Reducing these agricultural practices could help curb the evolution and spread of H5N1.

People can also take better care of themselves. At the individual level, most people can vaccinate against the common, seasonal influenza viruses that circulate every year. At first glance this practice may not seem connected to the emergence of avian influenza. But in addition to preventing seasonal illness, vaccination against common human varieties of the virus will reduce the odds of it mixing with avian varieties and giving them the traits they need for human-to-human transmission.
At the population level, societies can work together to improve nutrition and sanitation in the world’s poorest populations. History has shown that better nutrition increases overall resistance to new infections, and better sanitation reduces how much and how often people are exposed to new pathogens. And in today’s interconnected world, the disease problems of any society will eventually spread to every society.
For more than 10,000 years, human behaviors have shaped the evolutionary trajectories of infectious diseases. Knowing this, people can reshape these trajectories for the better.Ron Barrett, Professor of Anthropology, Macalester College

SAN DIEGO, CA, USA /EINPresswire.com/ — Missing teeth can have obvious consequences for your smile, but many people are not aware of how tooth loss affects their oral health, general well-being, and even their facial shape. Once a tooth is detached from the gums, there is no tooth root to stimulate the underlying jawbone; unfortunately, this often causes the bone structure to recede and lose volume. Bone loss can raise a number of aesthetic and functional concerns — particularly when a tooth has been without a replacement for a significant amount of time — including the shifting of surrounding teeth, an increased risk of gum disease, and changes in your jaw structure. In general, greater bone loss is experienced the longer an absent space remains unfilled. While jawbone recession can be debilitating, San Diego cosmetic dentist Landon Libby, DDS discusses potential solutions for bone loss to prevent further damage and regenerate additional bone density.
According to Dr. Libby, implant dentistry can offer a myriad of benefits for individuals with missing teeth, including the ability to maintain bone volume and preserve the full integrity of the jawbone after tooth loss. Using dental implants, implant dentistry aims to replace a missing tooth with an artificial tooth root and a custom-made restoration indistinguishable from a patient’s natural teeth. A titanium post is implanted into the jawbone during treatment, which serves as the “replacement” tooth root. Unlike other tooth replacement options that are not surgically affixed to the underlying bone, dental implants and implant-supported restorations promote new bone regeneration. Not only can this enhance a patient’s oral health and strengthen their jawbone, but implant restorations are also considered to look and feel the most similar to natural teeth. Best of all, implants can be used to replace a single tooth, multiple teeth in a row, or even a full dental arch.
It’s important to understand that every patient may not be a good candidate for dental implants, and bone grafting may be necessary prior to treatment to provide more support for implant placement. As a multi-stage process involving oral surgery, Dr. Libby stresses the importance of selecting an experienced, compassionate, and qualified dental team to place implants and provide a seamless patient experience.
About Landon Libby, DDS Dr. Landon Libby is a Mission Valley-based cosmetic dentist who provides cosmetic, restorative, and family dentistry treatments for patients in and around San Diego. As a DOCS-certified dentist with training in sedation dentistry, Dr. Libby strives to enhance patient comfort during every stage of treatment and redefine what it means to “go to the dentist.” After receiving his Doctor of Dental Surgery (DDS) from the Loma Linda University School of Dentistry, Dr. Libby went into private practice and has been serving the dental needs of the San Diego community for years.
