A faster shield against the next outbreak — held back by an outdated rulebook.

Monoclonal antibodies give your body ready-made protection against infectious disease — targeted, proven, and made without a live virus. Yet the rules haven't caught up with the science.

The 30-Second Version

What is a monoclonal antibody?

When your body fights an infection, it makes antibodies — precision-guided proteins that lock onto a specific threat. Scientists can now identify the best one, copy it, and give it to you directly — so you're protected right away.

Targeted

Designed to bind one specific pathogen — nothing more, nothing less.

Immediate

You receive the finished antibody, so protection doesn't wait on your immune system to build it.

No live virus

Made in the lab from a single antibody — not from a live or weakened pathogen.

The Science

How monoclonal antibodies work

A natural approach to immune defense — optimized by science for precision and speed.

01

Identify the target

Scientists isolate the most effective antibodies from recovered patients — or engineer them to target specific viral proteins.

02

Precision engineering

These antibodies are cloned and optimized for maximum potency and duration — extending protection for months from a single dose.

03

Neutralize on contact

Once administered, mAbs immediately bind to the pathogen, blocking it from entering cells and flagging it for immune cleanup.

04

Protection delivered

No immune activation needed. Your body receives ready-made defense that works alongside your natural immune system.

The Problem

Same science. Different rulebook.

When a virus mutates, a monoclonal antibody can be re-targeted to the new variant relatively quickly. But today's approval rules don't give mAbs the fast track that vaccines get.

~1 yr

vs
Antibodies today
~3 yrs

Face a longer road — even when the underlying antibody is already proven safe.

A treatment that could protect people in months can sit on the shelf for years. We're working to fix that.

The Science

Identical to the antibodies your body already makes

A therapeutic mAb isn't a foreign substance — it's the same class of protein your own immune system produces, just identified, copied, and given to you directly.

Understanding the Difference

A different tool than a vaccine

Both are valuable. But mAbs fill critical gaps that vaccines alone can't address — which is exactly why the approval rules should let them keep pace.

Monoclonal Antibodies

Precision-delivered protection

  • Immediate onset — works within hours
  • No immune-system activation required
  • Effective for immunocompromised patients
  • Rapidly adaptable to new variants
  • Single dose, months of protection
  • Used for prevention and treatment
Traditional Vaccines

Trained immune response

  • Takes 2–4 weeks to build protection
  • Requires a functional immune system
  • Less effective in immunocompromised
  • Slower to update for new variants
  • May require multiple doses / boosters
  • Primarily prevention-focused
The Advantage, Visualized

The immunity gap

Vaccines and natural infection take weeks to build protection. A monoclonal antibody bridges that gap — delivering defense from day one.

This Isn't Theoretical

Antibody treatments already in use

Real, approved monoclonal antibodies are protecting people from infectious disease right now.

FDA Approved

RSV protection for infants

A single-dose antibody is used to help protect newborns and infants through their first RSV season.

Published Evidence

Season-long malaria prevention

Clinical trials published in the New England Journal of Medicine showed a single antibody dose protecting adults across a malaria season.

In Use

Preventing recurrent infection

Antibody therapy is used to reduce recurrence of serious bacterial infections in vulnerable patients.
