Despite RFK Jr.’s public opposition, the USDA is planning to mass vaccinate poultry — a move that could drive mutations and spark a human pandemic.
This is a Public Health Disaster in the Making
The proposed vaccines (whether mRNA or antigen-based) are non-sterilizing, meaning they don’t stop infection or transmission.
This opens the door to antigenic shift — where the virus evolves rapidly under immune pressure, becoming more virulent and possibly jumping to humans.
A recent study by Li et al found that mass vaccination of poultry against H5N1 with a non-sterilizing vaccine during a widespread animal pandemic can accelerate viral evolution, leading to more virulent strains and increasing the risk of a human pandemic:
