Polio to COVID-19: Why Has Vaccine Confidence Eroded Over the Last 70 Years?

On the morning of April 12, 1955, newsrooms across the United States inked headlines onto newsprint: the Salk Polio vaccine was "safe, effective, and potent." This was long-awaited news. Americans had limped through decades of fear, unaware of what caused polio or how to cure it, faced with the disease's terrifying, visible power to paralyze and kill, particularly children.

The announcement of the polio vaccine was celebrated with noisy jubilation: church bells rang, factory whistles sounded, people wept in the streets. Within weeks, mass inoculation began as the nation put its faith in a vaccine that would end polio.

Today, most of us are blissfully ignorant of child polio deaths, making it easier to believe that we have not personally benefited from the development of vaccines. According to Dr. Steven Pinker, cognitive psychologist and author of the bestselling book Enlightenment Now, we've become blasé to the gifts of science. "The default expectation is not that disease is part of life and science is a godsend, but that health is the default, and any disease is some outrage," he says.

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.

What Causes Aging with Dr. David Sinclair

Last month, a paper published in Cell by Harvard biologist David Sinclair explored root cause of aging, as well as examining whether this process can be controlled. We talked with Dr. Sinclair about this new research.

What causes aging? In a paper published last month, Dr. David Sinclair, Professor in the Department of Genetics at Harvard Medical School, reports that he and his co-authors have found the answer. Harnessing this knowledge, Dr. Sinclair was able to reverse this process, making mice younger, according to the study published in the journal Cell.

I talked with Dr. Sinclair about his new study for the latest episode of Making Sense of Science. Turning back the clock on mouse age through what’s called epigenetic reprogramming – and understanding why animals get older in the first place – are key steps toward finding therapies for healthier aging in humans. We also talked about questions that have been raised about the research.
