The Global Vaccine Data Network's comprehensive COVID-19 vaccine safety study, funded by the CDC, was abruptly terminated due to budget cuts by the Trump administration. The study, led by Professor Helen Petousis-Harris and Professor Steven Black, aimed to evaluate vaccine effectiveness and address vaccine hesitancy. The funding cut has not only affected the research outcomes but also undermined the credibility of scientific institutions and researchers. The study's organizers are now seeking alternative funding to complete the research.
