#Immunogenicity
CDC FluView is back, and our fears look like reality.

50.8% of circulating H3N2 viruses belong to the 2a.3a.1-K subclade, which have 2 mutations in a very important antigenic site. Our own 2025-2026 vaccine immunogenicity data will be posted in the next couple of weeks.

Longer PMPC chains reduced immunological phagocytosis, extended plasma half-life, lowered immunogenicity, and improved therapeutic outcomes compared to native protein and shorter-chain conjugates.

[Articles] Safety, tolerability, and immunogenicity of the ChAdOx1 RVF vaccine against Rift Valley fever among healthy adults in Uganda: a single-centre, single-blind, randomised, placebo-controlled, dose-escalation, phase 1 trial
A single dose of ChAdOx1 RVF vaccine seemed to be safe, tolerable, and immunogenic in healthy adults in an RVF-endemic setting, eliciting humoral and cellular immunity. Further evaluation of the 5·0 × 1010 dose in larger and more diverse populations in areas susceptible to outbreaks is warranted.

A combination typhoid and non-typhoidal Salmonella polysaccharide conjugate vaccine in healthy adults: a randomized, placebo-controlled phase 1 trial | Nature Medicine
In sub-Saharan Africa, typhoidal and non-typhoidal Salmonella (NTS) are leading causes of invasive disease among young children. Trivalent Salmonella conjugate vaccine (TSCV) consists of Vi capsule polysaccharide conjugated to tetanus toxoid and core-plus-O-polysaccharides from the two most prevalent invasive NTS serovars conjugated to flagellin subunits. We conducted a first-in-human, randomized, placebo-controlled, phase 1 trial evaluating the safety and immunogenicity of TSCV. A total of 22 healthy adults aged 18−45 years were randomly allocated to 6.25-µg TSCV (n = 8), 12.5-µg TSCV (n = 10) or placebo (n = 4). The primary objective was the assessment of safety. The co-primary immunogenicity objective was the serum IgG response against the three vaccine polysaccharides and two flagellin carrier proteins. Here we show that TSCV was safe and well tolerated, meeting the prespecified safety endpoints, with the most common solicited symptom being short-lived injection site pain. For each

It's true that the FDA's limit on the amount of aluminum in [v-------] was based on immunogenicity and not safety data.

But LinkedIn doesn't want you to know that.

Here's an example of how censorship enables government-sanctioned disinformation about the "safety" of [v-------] to prevail. 👇

New PTK7-targeting antibody–drug conjugates (ADCs) use fully human, effector-null antibodies linked to a topoisomerase I inhibitor. Engineered for high stability, bystander effect and low immunogenicity, they overcome prior ADC limits, achieving potent, selective tumor killing with minimal toxicity.
