Vaccine Research Update: COVID Prevention, Malaria Rollout, Cancer Progress, and More!

From Invivyd’s FDA-cleared IND for its pivotal COVID prevention antibody to Liberia’s nationwide rollout of the RTS,S malaria vaccine, vaccine development is advancing on multiple fronts. Anixa and Cleveland Clinic completed their Phase 1 breast cancer vaccine trial, while Alzinova gained FDA Fast Track and IND clearance for its Alzheimer’s candidate ALZ-101. Bavarian Nordic posted positive pediatric mpox/smallpox data ahead of an EMA filing, Bharat Biotech’s trivalent Salmonella vaccine showed strong immunogenicity, and TransCode expanded into oncology vaccines with its Polynoma acquisition.

Why it Matters

Antibody-based COVID prevention (Invivyd) offers an option for at-risk groups that may not respond to, or prefer, vaccination.
RTS,S national rollout illustrates operational scaling of malaria immunization in high-burden settings.
Oncology vaccines continue to mature across prevention and adjuvant settings, with diversified antigens and combinations.
Neurodegeneration vaccine strategies are advancing beyond plaques toward oligomer-selective targets.
Pediatric mpox/smallpox data could broaden outbreak-response tools in Africa and beyond.

FAQ

What trials are in Invivyd’s REVOLUTION program for VYD2311?

DECLARATION is a BLA-enabling Phase 3 placebo-controlled prevention study with single-dose and monthly IM dosing. LIBERTY is an active-controlled safety and tolerability study versus mRNA vaccine with a co-administration arm [1].

Who is eligible in Liberia’s RTS,S rollout and how is it given?

Liberia targets children 5–15 months with four doses at 5, 6, 7, and 15 months, expanding beyond the 2024 regional launch to nine additional counties in 2025 [2].

What did Anixa’s Phase 1 breast cancer vaccine trial include?

Three cohorts, totaling 35 women: TNBC post-treatment, prevention in high-risk mutation carriers planning prophylactic mastectomy, and a pembrolizumab combination group. Final data are planned for SABCS on 11 Dec 2025 [3].

What does FDA Fast Track for ALZ-101 cover?

Fast Track and IND clearance enable Alzinova to run a US Phase 2 in early Alzheimer’s disease, using ADCOMS as primary endpoint, following Phase 1b tolerability and immune response signals [4].

What are the key pediatric findings for MVA-BN?

In children 2–11 years, immune responses were non-inferior to adults, with highest neutralizing titers in ages 2–5, and a safety profile similar to adults, supporting a 2026 EMA filing plan [5].

What pathogens does the trivalent Salmonella vaccine target?

S. Typhi plus iNTS serovars Typhimurium and Enteritidis, combining Typbar TCV Vi polysaccharide with two iNTS conjugates. Phase 1 adult data showed strong immunogenicity and tolerability [6].
