Eligibility Criteria

Inclusion Criteria

  • Male or female participants ≥65 years of age at the time of consent
  • Participating or participated in Study C4591001, received 2 doses of 30 µg BNT162b2 with the second dose given ≥6 months prior to the first vaccination in this study, and have not received a third dose of BNT162b2
  • Adults determined by clinical assessment, including medical history and clinical judgement, to be eligible for the study, including adults with preexisting stable disease
  • Adults who have no history of ever receiving a pneumococcal vaccine, or received a licensed pneumococcal vaccination ≥12 months prior to the first vaccination in this study

Exclusion Criteria

  • History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis)
  • Serious chronic disorder that in the investigator's opinion would make the participant inappropriate for entry into the study
  • Previous clinical or microbiological diagnosis of COVID-19
  • Previous vaccination with any investigational pneumococcal vaccine, or planned receipt of any licensed or investigational pneumococcal vaccine through study participation
  • Previous vaccination with any coronavirus vaccine, other than those received in Study C4591001
  • Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study
