The COVID-19 vaccines produced by Pfizer & Moderna were initially advertised as being ~95% effective against severe disease and ~90% effective at preventing an infection. However, as SARS-CoV-2 mutated and new strains emerged, vaccine efficacy diminished significantly. https://www.ecdc.europa.eu/en/publications-data/interim-analysis-covid-19-vaccine-effectiveness-healthcare-workers-ecdc-multi https://www.healthdata.org/covid/covid-19-vaccine-efficacy-summary
