Determining Discrete Data Points from the Sex and Gender Spectra

Sex and gender play an important role in health and disease, yet data collection methods for these demographics are outdated, insufficient, or non-existent.

Expert Insight

Helping Carry the Vaccination Decision-Making Burden during Pregnancy

With limited data on the efficacy and safety of vaccines in pregnant people due to antiquated policies, this population is either unfairly blocked from receiving vaccinations or forced to decide to get vaccinated without clear public health guidance. The COVID-19 pandemic has been an opportunity to prioritize pregnant people, but there is yet again a lack of data on COVID-19 vaccination and pregnancy.

Pandemic Data Outlook

Preparing State Data Systems for Booster Doses and Breakthrough Cases

As concerns about breakthrough infections increase and booster doses become a reality, states must prepare their data collection systems and public dashboards to best collect and disseminate this information. These new data streams could be incredibly useful to controlling COVID-19 if states follow certain recommendations and prepare accordingly.

Expert Insight

Let’s Talk About Sex, Gender, and Intersectionality

Sex and gender combine with other societal constructs such as race and age to determine how a person will respond to a disease like COVID-19. Detailed data collection on patients’ sex and gender will be necessary to appropriately tailor medical interventions and understand the underlying mechanisms of disease and this pandemic.
