(CNN)If the health misinformation currently spreading regarding coronavirus vaccines existed during the days of polio, it would have never been eradicated, Dr. Anthony Fauci, President Joe Biden’s chief medical adviser, said Saturday.
Asked by CNN’s Jim Acosta about the misinformation spread by Fox News regarding the Covid-19 vaccines, Fauci said, “We probably would still have polio in this country if we had the kind of false information that’s being spread now.”He added, “If we had that back decades ago, I would be certain that we’d still have polio in this country.”The statement comes as dangerous falsehoods about Covid-19 vaccines are swirling and as health experts warn of the more transmissible Delta variant’s increasing spread among unvaccinated Americans.

And it’s the communities with lower vaccination rates that are at risk.”Despite the rise of the Delta variant, still 97% of people who are hospitalized or killed by this virus are unvaccinated,” said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital in Philadelphia and a member of the US Food and Drug Administration’s vaccine advisory committee. “If the Delta variant were escaping, essentially, immunity induced by vaccination, then you should have seen a rise in people who are vaccinated, but nonetheless were still hospitalized and killed. And that hasn’t happened.”Covid-19 vaccines are effective at preventing severe disease, experts say, as rising cases threaten unvaccinatedAmong those states that have fully vaccinated less than half of their residents, the average Covid-19 case rate was 11 new cases per 100,000 people last week, compared to 4 per 100,000 among states that have fully vaccinated more than half of their residents, according to a CNN analysis of data from Johns Hopkins University.”If you look at the extraordinary success in eradicating smallpox and eliminating polio for most of the world — and we’re on the brink of eradicating polio — if we had had the pushback for vaccines the way we’re seeing on certain media, I don’t think it would’ve been possible at all to not only eradicate smallpox, we probably would still have smallpox,” said Fauci.Polio once was a common virus. In some young children it can affect the nerves and cause muscle weakness or paralysis. There is no treatment and no cure but getting vaccinated can prevent infection.Just in August 2020, polio was eradicated from Africa after governments and non-profits had worked since 1996 to eliminate the virus with sustained vaccination campaigns. Polio has now been eradicated in the Americas, Southeast Asia, Europe, most of Australasia and in Africa. Wild strains of polio circulate now in only two countries: Afghanistan and Pakistan.
