About the Film

Virulent: The Vaccine War examines the consequences of vaccine hesitancy and denial. It’s a war anti-vax activists have been fighting for more than a decade. And Covid-19 is what they practiced for—a national conversation about vaccine safety and mandates.

I have a lot of patients who may be hesitant about vaccines, but when the COVID-19 pandemic hit, it brings reality and smacks you in the face. Sadly, the anti-vaccine community began to co-opt the pandemic and started spinning conspiracy theories.
—Dr. Todd Wolynn

I don’t need any conspiracy to create job security for infectious diseases. Nature and the world create that just fine.
—Dr. John V. Williams

Mother Nature has been trying to kill us ever since we crawled out of the ocean onto land. The only reason we live 30 years longer than we did a hundred years ago is because we fought back actively and hard.
—Dr. Paul Offit

If you have the power to not cause harm to anybody else, you should use that.
—Hannah Grinnan (heart transplant recipient)

Laura Davis (Producer) &
Tjardus Greidanus (Director/Editor/Cinematographer)

Laura and Tjardus specialize in making impactful documentaries about science and medicine. Their latest project, Virulent: The Vaccine War, examines the history of vaccine hesitancy and the galvanizing effect Covid-19 has had on anti-vaccination activists. It is their follow-up to the CINE Golden Eagle-winning A Shot to Save the World about the creation of the Salk polio vaccine which featured an exclusive interview with Bill Gates and streamed on Paramount+ throughout 2020.

A Shot to Save the World film originally premiered on the Smithsonian Channel and BBC Four and was honored by the CDC Foundation on World Polio Day 2013.

Another feature documentary, Burden of Genius, an exploration of Dr. Thomas Starzl’s pioneering work in organ transplantation, is heading to public television in 2022 following weeks of sold-out screenings at the Carnegie Science Center and hundreds of screenings at top transplant centers including Stanford, Columbia, Harvard-Mass General, Johns Hopkins, Cleveland Clinic, UPMC, Duke and the University of Chicago as well as at transplant conferences around the world.

Before turning to documentaries, Laura and Tjardus made hundreds of marketing featurettes for Sony Pictures Entertainment, Universal Pictures, Paramount, Twentieth Century Fox and Warner Bros. Over two decades, they worked for some of the world’s most respected directors producing over 30 projects for Martin Scorsese, James L. Brooks, Mike Nichols, Cameron Crowe and Michael Mann. They also made the narrative features Hellbent (2018) and A New York Heartbeat (2013), which gave Emmy Award-winner Rachel Brosnahan (The Marvelous Mrs. Maisel) her first starring role.

Laura also produced the documentaries Everest: On Location in the Death Zone (Miramax) and The Chef & The Architect (Food Network), and the telefilms, Someone Else’s Child (ABC) and Still Holding On: The Legend of Cadillac Jack (CBS). She got her start as an interviewer on NBC Radio and later for Showtime/The Movie Channel following her graduation from Cornell University.

Dutch-born Tjardus is currently prepping The Shot, a narrative feature about Dr. Jonas Salk and his creation of the polio vaccine, based on A Shot to Save the World. He successfully straddles documentary and narrative filmmaking bringing to both a love for authenticating detail and character-driven stories.

Virulent does such an effective job combatting vaccine skepticism on so many different fronts.”
Virulent explores the history of vaccines and the perspectives of those who oppose them in light of the recent pandemic [including] that they cause autism (spoiler: they do not.)”
