I did not watch the video, but my husband and I have not got a vaccination in over 10-15 years. Also we have not vaccinated any of our children.
We get the flu every year and fight it naturally with ginger, garlic, Apple cider vinegar, broth, and fasting. Plus other herbs.
WE have traveled a lot and have been fine.
We also only go to the doctors when absolutely necessary. No reason for well visits, if we are well no need for a doctor, pressure, or an extra bill.
Eat healthy, exercise regularly, get sun, pray, try to limit stress (hardest for me with 5 little ones and my melancholic temperament).
Overall I believe this is what has healed us in the past and will help us in the future. Also any ailments are great penances ;D
