No need to protect me or my family.. our genetic line shows no issue with any of the diseases. According to the US's CDC people start to show waning titers at 22 days, especially to the measles.... so with that variance...it is statistically impossible to produce "herd" immunity in a population. Regardless, excited about this format because I join to publish science. I have experimented on various different species with vaccines...long term studies, short term...and even purposely exposed the "herd" (of goats actually) to an ill animal. I have also found contaminants...ect. Excited to share the results and my documented evidence. So enjoy the ride!!!
