If you asked this question of parents in the US in the 1950s, the response would likely be unequivocal.
Our history books paint a bleak picture of life during the polio epidemic: Deserted playgrounds, empty swimming pools, restricted travel and imposed quarantines.
Movie theaters were closed to avoid spreading the disease. Children were kept alive in hospitals by an earlier version of respirators called "iron lungs," which allowed them to breathe when the virus had paralyzed their chest muscles.
The parallels with the coronavirus are obvious, and not only in the societal impact of an infectious disease before a vaccine was discovered. Polio was and still is another silent killer, primarily spread from person to person. Like Covid-19, it could display no visible symptoms in many infected people, flu-like symptoms in others and more serious, disabling or sometimes fatal effects in others. In the late 1980s, polio was endemic in 125 countries,
according to the World Health Organization, and was infecting about 350,000 children a year
nearly 1,000 children every day.
But the public reaction to these two deadly diseases diverges in significant ways. When Jonas Salk developed a successful vaccine against polio in 1955, it was celebrated emphatically.
Panic and skepticism over the vaccine existed but were relatively muted. However, a recent AP/NORC poll
found that if a successful Covid-19 vaccine is discovered, only 49% of Americans say they would get it, while the rest of the population is either opposed or uncertain.
How have we reached this point, where even during an extraordinary international public health crisis, there are still those who oppose vaccination, despite its track record in saving millions of lives?
Thanks to the Salk vaccine and Albert Bruce Sabin's oral polio vaccine, and the work of the Global Polio Eradication Initiative, of which Rotary International was a founding partner, more than 18 million people have been saved from lifelong paralysis, and 1.5 million deaths have been prevented, according to the CDC
. No one has suffered from the disease in the US since 1979
In the US, before those vaccines are licensed, a rigorous vaccine safety system ensures that they are safe and effective, involving multiple rounds of testing and clinical trials. Backed by the Food and Drug Administration and the CDC, this system upholds, in the words of Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, the safety and "scientific integrity"
of any new vaccine. Even with the accelerated timelines attempted in the development of a coronavirus vaccine, safety is still prioritized by what doctors describe as many steps being executed in parallel
compared to the traditional linear, years-long model of vaccine development.
Yet, in the face of extensive regulatory measures and an abundance of evidence proving the safety and efficacy of vaccines, even before coronavirus struck, vaccine-preventable diseases, including measles and flu viruses, were already resurging in the US.
These resurgences have materialized in part because of falling vaccination rates. A Health Testing Centers study
last year found that more than half of US states have experienced a decline in kindergarten vaccination rates over the past decade.
The phenomenon of vaccine hesitancy the reluctance or refusal to vaccinate despite the availability of vaccines is of global concern.
For others, the act of refusing vaccines and placing others at risk is no less than an expression of their identity, a twisted manifestation of "rugged individualism," the term widely used by Herbert Hoover.
However, the overwhelming number of vaccine-hesitant parents are themselves victims of a massive anti-vaccine misinformation campaign launched on more than 400 websites,
and amplified through social media, political action committees and organized rallies.
Perhaps vaccine debates continue, in part, due to the fact that many young parents simply don't know anyone who has suffered the ravaging effects of a vaccine-preventable disease such as polio.
In a way, vaccines have become victims of their own success.
But the costs are too great to allow for irrational fear of vaccines to outweigh the real consequences of catching a disease such as Covid-19, which is claiming lives, and causing unprecedented changes in society. Tragically, the anti-vaccine movement has expanded from one making phony claims linking vaccines to autism, to one tied to extremist groups who see social distancing as a form of conspiracy or government plots.
When the bias against science spreads to the sphere of public health, it has a dangerous effect, particularly in times of crisis.
This is compounded by another devastating consequence of the Covid-19 pandemic: the very real possibility of further increased rates of vaccine-preventable diseases. This is a real threat in cities facing the largest Covid-19 outbreaks, which are seeing a decrease in vaccination rates
given parents' fear of taking their children to hospitals and clinics. On a global level, WHO recently announced that 80 million
babies, many in vulnerable countries, are not getting lifesaving routine vaccinations in light of the pandemic.
With staggering statistics like this, it is more important now than ever before that we rely on science, facts and research. The lives and livelihood of millions of children, not just vulnerable adults, are at stake.
We hope that when we have a safe and proven vaccine against coronavirus, this pernicious thinking will be resisted as vaccination protects us all against disease. For the good of every generation, and every nation, the choice to embrace a future coronavirus vaccine -- and vaccines in general -- is a simple one.
