If you've ever had qualms about eating genetically modified (GM) foods, you'd likely be deeply concerned about receiving a GM vaccine as well.
Such vaccines are already being produced – some are even on the U.S. Centers for Disease Control and Prevention's (CDC) recommended vaccine schedule – even though, as is the case with GM foods, we know very little about their long-term effects.GM Vaccines You May Have Given to Your Kids...
Many are unaware that, despite the completely unknown long-term health consequences, GM vaccines are already in use and have been administered to American infants, children and adults for many years. Among them:

- Rotavirus vaccine: Live attenuated vaccines first licensed for infants and children licensed in 2006, which either contain genetically engineered human rotavirus strains or human-bovine hybridized reassortment rotavirus strains4 
- HPV vaccine (Gardasil or Cervarix): A recombinant vaccine licensed in 2006, which is prepared from virus-like particles (VLP's) and may also include use of an insect-cell Baculovirus expression vector system for production
