ClinicalTrials.gov[1] lists 2028-12-11 as the estimated primary completion date; a sponsor's estimate, and trials of this size routinely slip.
Pfizer's phase 3 trial of C.Difficile Vaccine in clostridoides difficile associated disease reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 32,500 participants. The purpose of the study is to learn about how effective, safe, and tolerable the Clostridioides difficile (C. difficile) vaccine is in decreasing the number of C. difficile infections (pCDI) in adults 65 years of age or older. The participants will receive either the C. difficile vaccine or placebo (saline). A placebo does not contain any active ingredients. The vaccines will be given as a shot into the upper arm muscle. This study looks at the number of diarrhea (loose stools) events related to a C. difficile infection, so the length of the study can change. If these events happen quickly, the study may finish sooner; if they happen slowly, it could take longer. Sometimes, the study might stop early if the vaccine clearly does not work. Participants will stay in the study until enough events have occurred to answer the main question.

ClinicalTrials.gov[1] lists 2028-12-30 as the estimated primary completion date; a sponsor's estimate, and trials of this size routinely slip.
Pfizer's phase 3 trial of PG4 in pneumococcal disease reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 2,400 participants. The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs that can cause pneumonia (lung infections), meningitis (brain infections), and otitis media (ear infections) in infants when compared to the pneumococcal vaccine that is currently in use, 20vPnC (Prevnar 20®). This study will test if the new pneumococcal vaccine is as safe as the one that is currently in use. This new vaccine can possibly provide additional protection against germs that cause pneumococcal disease that are not included in the vaccines that are currently given to infants. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. There are two groups in this study. All participants will be assigned to one of the two groups.

The largest step between consecutive strikes (taking the highest quote seen so far where a later strike is quoted lower) is Jan 1, 2029 (10%) to Jan 1, 2030 (24%), so the window opens on Jan 1, 2029. Quotes are bid/ask midpoints read on 27 October 2026. Estimated contract-count-times-last-price volume across active strikes is about US$1,102 (7,559 contracts); this is not reported cash turnover.[1]
