Pollock is a cardiovascular invasive specialist.[2] She was elected to the Missouri House of Representatives in 2018 and re-elected in 2020.[3]
While in the House, Pollock promoted anti-vaccination legislation.[4] During the COVID-19 pandemic in Missouri, Pollock was one of a number of Republican state lawmakers who promoted and amplified misinformation about COVID-19 and the COVID-19 vaccine. She promoted claims, promoted by right-wing media outlets, that the vaccines approved for use in the U.S. had "been rushed" and had questionable efficacy.[4] In late 2020, Pollock introduced a bill to bar discrimination against persons who chose not to be vaccination against COVID-19.[4]
In the 2021 legislative session, Pollock sponsored a measure to expand school vaccination opt-outs, allowing more children to enter school without being vaccinated against infectious diseases, such as polio, measles, and mumps.[4] Pollock had introduced a similar bill in 2020, but it did not advance.[2][5] Pollock's bill would have eliminated vaccine requirements for private school students, and would also make it easier to obtain exemptions from vaccine requirements to attend public schools and universities.[2][5] During the legislative debate, Pollock said, "We need to rein in our schools and our health departments."[5] The Missouri State Medical Association and the Missouri chapter of the American Academy of Pediatrics opposed the bill due to the supposed risks it presented to public health.[2][5] The House Elementary and Secondary Education Committee passed the bill 10–6, but it was defeated in April 2021 on the House floor on a 79–67 vote.[4][6]
