Bivalent Boosters for Young Children Are Elusive. The Search Is On for Ways to Improve Access.

Bivalent Boosters for Young Children Are Elusive. The Search Is On for Ways to Improve Access.

Theo, an 18-month-old in rural Nebraska, walks with his father in their backyard. For many toddlers, the barriers to accessing COVID-19 vaccines are many, such as few locations giving vaccines to very young children.

It’s Theo’s* first time in the snow. Wide-eyed, he totters outside holding his father’s hand. Sarah Holmes feels great joy in watching her 18-month-old son experience the world, “His genuine wonder and excitement gives me so much hope.”

In the summer of 2021, two months after Theo was born, Holmes, a behavioral health provider in Nebraska lost her grandparents to COVID-19. Both were vaccinated and thought they could unmask without any risk. “My grandfather was a veteran, and really trusted the government and faith leaders saying that COVID-19 wasn’t a threat anymore,” she says.” The state of emergency in Louisiana had ended and that was the message from the people they respected. “That is what killed them.”

The current official public health messaging is that regardless of what variant is circulating, the best way to be protected is to get vaccinated. These warnings no longer mention masking, or any of the other Swiss-cheese layers of mitigation that were prevalent in the early days of this ongoing pandemic.

The problem with the prevailing, vaccine centered strategy is that if you are a parent with children under five, barriers to access are real. In many cases, meaningful tools and changes that would address these obstacles are lacking, such as offering vaccines at more locations, mandating masks at these sites, and providing paid leave time to get the shots.

Scientists redesign bacteria to tackle the antibiotic resistance crisis

Probiotic bacteria can be engineered to fight antibiotic-resistant superbugs by releasing chemicals that kill them.

In 1945, almost two decades after Alexander Fleming discovered penicillin, he warned that as antibiotics use grows, they may lose their efficiency. He was prescient—the first case of penicillin resistance was reported two years later. Back then, not many people paid attention to Fleming’s warning. After all, the “golden era” of the antibiotics age had just began. By the 1950s, three new antibiotics derived from soil bacteria — streptomycin, chloramphenicol, and tetracycline — could cure infectious diseases like tuberculosis, cholera, meningitis and typhoid fever, among others.

Today, these antibiotics and many of their successors developed through the 1980s are gradually losing their effectiveness. The extensive overuse and misuse of antibiotics led to the rise of drug resistance. The livestock sector buys around 80 percent of all antibiotics sold in the U.S. every year. Farmers feed cows and chickens low doses of antibiotics to prevent infections and fatten up the animals, which eventually causes resistant bacterial strains to evolve. If manure from cattle is used on fields, the soil and vegetables can get contaminated with antibiotic-resistant bacteria. Another major factor is doctors overprescribing antibiotics to humans, particularly in low-income countries. Between 2000 to 2018, the global rates of human antibiotic consumption shot up by 46 percent.

Meet Dr. Renee Wegrzyn, the first Director of President Biden's new health agency, ARPA-H

Today's podcast guest, Dr. Renee Wegrzyn, directs ARPA-H, a new agency formed last year to spearhead health innovations. Time will tell if ARPA-H will produce advances on the level of its fellow agency, DARPA.

In today’s podcast episode, I talk with Renee Wegrzyn, appointed by President Biden as the first director of a health agency created last year, the Advanced Research Projects Agency for Health, or ARPA-H. It’s inspired by DARPA, the agency that develops innovations for the Defense department and has been credited with hatching world-changing technologies such as ARPANET, which became the internet.

Time will tell if ARPA-H will lead to similar achievements in the realm of health. That’s what President Biden and Congress expect in return for funding ARPA-H at 2.5 billion dollars over three years.
