The main concerns about vaccines, even for those who don’t believe the statistics about safety, is on the cognitive development of infants and young children
As such, the effects on a sixty year-old getting a shingles vaccine wouldn’t be a concern for the anti-vaxers.
I disagree. Many parents are concerned about cognitive effects, yes, but most parents I know are opposed to the vaccines because they are obtained from the use of aborted fetal cells as culture. So their opposition is based on morality.
Also, I would note there are ZERO studies to demonstrate the long term safety of injecting humans with DNA remnants from other humans. There are some questions starting to arise about the astronomical increase in cancers of young adults & whether that can be linked to genetic contaminants found in vaccines.
