A universal influenza vaccine?
Researchers aim at more conserved parts of HA. Seasonal updates remain the licensed reality.
Darker cells mean a higher score for this topic on that metric.

Quick answers
Where should I start with Vaccines and immunity?
Read Identity → How they live → Body & health, then use compare rails.
Is this page advice for Vaccines and immunity?
Public-health education — not a care plan, prescription, or outbreak briefing.
What does the local lens add?
It names everyday desks for Change & defence before English norms look universal.
Are the scores a ranking of Vaccines and immunity?
No — editorial 0–100 browsing aids inside this atlas only.
How do I compare Vaccines and immunity to neighbours?
Use related cards and best-of / quiz rails after the first three chapters.
Which chapter is densest?
How they live and Body & health carry mechanisms; skim Identity first.
Some pathogens change too fast or hide too well for today's licensed platforms. That is a research frontier, not a verdict against all vaccines.
Durability after COVID-era shots taught the public that memory is not one number for every virus.
Open questions
Why no HIV vaccine yet?
Extreme diversity and a latent reservoir have defeated many candidates. Trials continue.
How long does memory last?
It depends on the antigen, the platform and the person. Serology is a partial window.
Can we vaccinate against resistance?
Vaccines that prevent bacterial disease can cut antibiotic courses — an indirect stewardship tool.
How is trust rebuilt after rumors?
Transparent safety data and local messengers matter more than scolding. That is social science, not a jab technique.
The frontier includes delivery in places without reliable electricity — a logistics problem as much as a molecular one.

Mutation and variants
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread.
Familiarity 92Antibiotic resistance
A shared drug budget under selection in hospitals, farms and wastewater — stewardship, not a lab manual.
Familiarity 85Biofilms
Surface cities of microbes — plaque and catheters explain persistence, without a grow-your-own kit.
Familiarity 38Hygiene and balance
Clean water saves lives; missing old microbial partners is a separate, still-debated immune story.
Familiarity 70Horizontal gene transfer
Sideways DNA traffic — conjugation, transduction, transformation as names and history, not protocols.
