In this episode of TWiV 1314, Vincent Racaniello and guest Daniel Griffin deliver a comprehensive clinical update on the latest developments in virology, with a strong emphasis on vaccine safety, public health policy, and emerging infectious disease threats. The conversation begins with a critique of a flawed Politico poll that misleadingly suggests declining public trust in vaccines, arguing that the poll's biased questions distort the reality—most Americans still support vaccines and recognize their protective benefits. The hosts express outrage over the CDC's delay in publishing a study showing the COVID-19 vaccine's effectiveness in reducing hospitalizations and emergency visits, attributing the delay to political interference, particularly from high-level appointees like Dr. Bhattacharya, who lacks expertise in epidemiological analysis. They highlight the broader danger of politicizing science, contrasting historical examples of political support for public health with current efforts to undermine vaccine credibility. The episode then shifts to emerging threats, including the potential for vampire bats to transmit chronic wasting disease (CWD) to humans and livestock, a scenario supported by new research on prion exposure via bat guano and feeding behaviors. The discussion continues with compelling evidence from a JAMA Oncology study showing a 54% reduction in HPV-related cancers among vaccinated males, reinforcing the role of vaccines as cancer-preventing tools. The hosts also emphasize the cardiovascular benefits of flu vaccination, citing a Danish study that found vaccinated individuals had significantly lower risks of heart attack and stroke following flu infection. Additional topics include the resurgence of measles, the ongoing threat of pediatric flu deaths, the devastating impact of the pandemic on marginalized communities as revealed by burial data from New York’s Heart Island, and the long-term burden of pediatric long COVID. The episode closes with a call to support the Floating Doctors fundraiser and a reminder that science-based public health measures remain essential.
Vaccine safety polls are often misleading due to biased question design; most Americans still support vaccines and believe they protect families.
The CDC’s delay in publishing a study showing strong COVID-19 vaccine effectiveness in reducing hospitalizations is likely politically motivated and undermines public trust.
Vampire bats may act as vectors for chronic wasting disease, posing a potential zoonotic threat due to their feeding on infected deer and co-roosting with other species.
HPV vaccination in males reduces the risk of HPV-related cancers by 54%, highlighting vaccines as powerful tools in cancer prevention.
Flu vaccination significantly reduces the short-term risk of heart attack and stroke following infection, underscoring the broader health benefits of vaccines.

Vaccine Poll Critique and the Politics of Science
“The questions they ask them suck. I think that's the problem is how you ask them, how you ask the questions. They're totally biased.”
CDC Delay of Key COVID Vaccine Study
“This is a lie and this is nonsense. And as you know, they are holding it back only because it says good things about COVID vaccines and they don't like that.”
Vampire Bats and the Threat of Chronic Wasting Disease
“The idea is the bats may feed on infected animals like deer, cervids. This is very interesting. It's not something I thought of.”
HPV Vaccine and Cancer Prevention in Males
The hosts highlight a major JAMA Oncology study showing a 54% reduction in HPV-related cancers among vaccinated males aged 9–26, reinforcing the importance of expanding HPV vaccination to boys and young men.
Flu Vaccination and Cardiovascular Protection
A Danish study is discussed showing that flu vaccination reduces the risk of heart attack and stroke by nearly half in the week following infection, due to reduced systemic inflammation and destabilization of atherosclerotic plaques.
“We've got a brand new disease. We know nothing about it. But you know what? I'm going to just say, let it rip. Let's see what happens. Very smart.”
“This is a lie and this is nonsense. And as you know, they are holding it back only because it says good things about COVID vaccines and they don't like that.”
“Over a million people died and what we're seeing a disproportionate number of them were people who already were disadvantaged.”
