This attached article is about what is one of the concerns of Secretary Kennedy that vaccines could create a medium for virus mutation Below is AI summary of the article and I attached the article
The article is "Imperfect Vaccination Can Enhance the Transmission of Highly Virulent Pathogens"
Why Vaccine Design Matters
Some vaccines stop people from getting sick but don’t fully block the spread of germs. That can be helpful—but in rare cases, it might let stronger, more dangerous versions of a virus survive and spread.
A study in chickens showed that when a vaccine didn’t stop infection, it allowed a deadly virus to keep circulating. Scientists are now watching closely to make sure human vaccines don’t accidentally help harmful germs evolve.
💡 The takeaway for families: Vaccines are powerful tools, but they work best when they protect both the person and the community. That’s why scientists keep improving them—to make sure they’re safe, strong, and stop the spread.
A study using Marek's disease virus in poultry shows that by reducing natural selection against highly virulent strains, imperfect vaccination enables the spread of viral strains that would otherwise be too lethal to persist.
