She has also worked for the Hebrew University of Jerusalem and the Israeli Ministry of Justice's Department of Public Law.

While studying there, Reiss worked as a teaching assistant and won the Outstanding Graduate Student Instructor Award.

There had been stories on the news about a whooping cough epidemic, which prompted Reiss to seek advice from her doctor on how to protect her child.

After that first encounter with anti-vaccine arguments, Reiss says she started reading more about the claims made by people opposing vaccines and the refutations provided by experts.

[14][15] In 2015, Reiss and coauthors Charlotte A. Moser and Robert L. Schwartz published a paper with the title ″Funding the Costs of Disease Outbreaks Caused by Non Vaccination″, in which they propose the creation of a no-fault fund paid by parents who refuse to vaccinate their children.

This fund would act as a tax which would cover the public health costs generated as a consequence of non-vaccination.

In her testimony, she argued that the legislature has the leeway to require school immunization, and that non-medical exemptions are unnecessary.
