San Antonio emergency room physician Dr. Nayeli Rodulfo-Zayas spent much of last summer treating patients with severe COVID-19 infections in the intensive care unit, too often watching them die from the insidious disease.

Dr. Rodulfo found out that she was expecting her second child during the height of the pandemic. As it did for so many pregnant women, the raging virus sparked an avalanche of additional anxiety within Rodulfo.  In December 2020, the Food and Drug Administration issued its first emergency use authorization for Pfizer’s COVID-19 vaccine. Rodulfo was 31 weeks pregnant when she was given the first dose of the vaccine that month.

“I basically was excited and happy and felt a sense of relief to get this vaccine,” Rodulfo said.
