Primary Outcome Measures :
  1. Percentage of participants reporting prompted local reactions within 10 days after vaccination [ Time Frame: 10 days ]
    Prompted local reactions (redness, swelling, pain) after vaccination

  2. Percentage of participants reporting prompted systemic events within 7 days after vaccination [ Time Frame: 7 days ]
    Prompted systemic events (fever, headache, chills, fatigue, muscle pain, joint pain) after vaccination

  3. Percentage of participants reporting Adverse Events (AEs) within 1 month after vaccination [ Time Frame: 1 month ]
    Adverse events occurring within 1 month after vaccination

  4. Percentage of participants reporting Serious Adverse Events (SAEs) within 6 months after vaccination [ Time Frame: 6 months ]
    SAEs occurring within 6 months after vaccination


Secondary Outcome Measures :
  1. Pneumococcal opsonophagocytic activity (OPA) geometric mean titers (GMTs) in participants vaccinated with 20vPnC [ Time Frame: 1 month after vaccination with 20vPnC ]
    Pneumococcal OPA GMTs 1 month after 20vPnC

  2. Geometric mean concentration (GMC) of SARS-CoV-2 full-length S-binding antibody levels in participants vaccinated with BNT162b2 [ Time Frame: 1 month after vaccination with BNT162b2 ]
    SARS-CoV-2 full-length S-binding antibody levels 1 month after BNT162b2

  3. Geometric mean fold-rise (GMFR) in SARS-CoV-2 full-length S-binding antibody levels from before vaccination to 1 month after vaccination in participants vaccinated with BNT162b2 [ Time Frame: 1 month after vaccination with BNT162b2 ]
    GMFR in SARS-CoV-2 full-length S-binding antibody levels from before to 1 month after BNT162b2

Ages Eligible for Study:   65 Years and older   (Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
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
