Bar width shows how precise the guidance is — a pin is a stated date, a wide band a six-month window. Deeper blue means more of the thesis rides on the event; it is not a view on the stock.

Verdict history (5 calls)

Every verdict Biotech Distilled has published on Vaxcyte, oldest first — the full history, never a selection. How calls are scored: the track record.

  1. Watch Vaxcyte (PCVX) — Scientific Deep Dive for VAX-31 and the PCV Franchise The chemistry is real and the balance sheet is elite, but management's own deck pre-announces serotype misses against a tightened 0.667 noninferiority bar, and the U.S. recommending body is under a federal court stay — the thesis converts only on a clean OPUS-1 serotype table.
  2. Watch UPDATE: Vaxcyte (PCVX) - The Factory Got Its Papers The Visp manufacturing suite was certified and handed over on August 1, retiring one of four required sequential conditions, but OPUS-1 data, the lot-to-lot study, and a functioning ACIP remain outstanding before a Buy conversion.
  3. Watch UPDATE: Vaxcyte (PCVX) - The Clock Is Set for October OPUS-1 topline narrowed to end-October and Vaxcyte hired Pfizer's former vaccines CMO to argue the totality-of-evidence case, but the binary is unchanged and the entry price has risen to $61.17 — 22% above the February offering.
  4. Buy core UPDATE: Vaxcyte (PCVX) - The Table Came Back Clean OPUS-1 met all prespecified primary endpoints with only two individual misses versus PCV21 (versus a guided five), serotype 3 cleared through the PCV20 escape hatch as anticipated, and the binary that anchored the Watch stance has been retired on better-than-guided terms.
  5. Buy core UPDATE: Vaxcyte (PCVX) - The Bill Is Paid, the Infant Bar Just Rose The ~$1.1B October raise funds the adult program through its 1H 2028 BLA with ~$3.4B pro forma, but the infant Phase 3 now faces the stricter 0.667 noninferiority bar and Pfizer holds a dated 2029 infant submission timeline, making the 1H 2027 infant readout the next material decision point.
