This is not the first time someone has said vaccinated people are more contagious than unvaccinated people.
It’s been known in veterinary practice forever
#2 Virus Shedding Is Virus Sharing
Many vaccines given to dogs are modified live virus (MLV) vaccines. MLV vaccines are used because they stimulate cell-mediated immunity better than killed viruses. Examples are distemper, adeovirus-2 (hepatitis, canine respiratory virus), parvovirus, intranasal bordetella, intranasal coronavirus and parainfluenza.
These vaccines can be shed in feces and urine for weeks after vaccination. Studies on dogs vaccinated with CPV-2 parvovirus show that the virus can remain in the blood stream and be shed via feces for as long as three to four weeks after vaccination.
This means these diseases can be spread through vaccination. Think about the dog who gets a bordetella shot a few days before going to stay at a boarding kennel. He’ll be shedding the disease for up to 7 weeks after vaccination … exposing every other dog at the facility to kennel cough.
The other problem is that MLV vaccines can make your dog ill. When MLV vaccines are given to animals with compromised immune systems they can cause a weakened form of the virus they’re supposed to protect against. Even the American Animal Hospital Association (AAHA) admits this, stating, “Since it is a truly live virus of a disease that we are trying to prevent, there is a small risk that the inactive virus can revert into the true form of the virus.”
Holistic veterinarian Patricia Jordan DVM explains that the leptospira organism can become a source of infection for humans in contact with a dog vaccinated for leptospirosis. Dr Jordan has personally witnessed several cases in which she had no doubt that a leptospirosis vaccine was the cause of subclinical infection in a dog and therefore could be transmitted to a human.
Dr Jordan says: “Leptospira can and will shed in a vaccinated dog and in turn, infect any humans living in the same household!”
When a duck hunter contracted leptospirosis in California, the state’s field study didn’t find any leptospira in the bodies of water he frequented. This strongly suggests that the man became infected through transmission of the leptospira from his vaccinated dog.
