proselytizing for others to follow their lead. (Or their supporters would have.)
Think of the harm that could have done.

(By "cured," I mean what if he had coincidentally gotten better own his own and they had attributed his improvement to the syrup.)

because I haven't followed this issue

The anti-vaxxers roots are in the preservative used in vaccines and flu shots
from the mid-80s on - thimerosol

Prior to that some flu vaccines were without preservative as they were refridgerated
which was expensive

It was also used in contact lens solutions for awhile

I was sensitive to flu shots, and had other mercury sources and issues
so I ditched flu shots for almost 20 years

Now they have largely or entirely removed the mercury based preservative

I got my first flu shot last winter, first in 14 years, and second in 22

I had no adverse reaction from it. No pain, no fever, no malaise, no aches

I'm not supportive of the anti-vax crowd, that is very irresponsible

but I'm glad they've acted to reduce mercury, and there must be a scientific
reason why they did it.

Bobby Kennedy Jr. wrote a book about this a couple of years ago.

Thimerosal has been taken out of kids' vaccines, but it's still found in some flu vaccines:

Just as thimerosal largely left the pediatric vaccine schedule, prenatal exposure to it increased, though, in an insidious and potentially even more dangerous fashion: through the flu vaccine. In 2002, the CDC began recommending annual flu vaccines for healthy infants between the ages of six and 23 months of age. Not long after, in 2004, the recommendations were extended to pregnant women in all stages of pregnancy. And in 2010, the CDC advised that every American, including pregnant women and young children, beginning at six months of age, get an annual flu shot. Many multi-dose flu vaccines contain thimerosal. American children born today, if their parents follow the annual flu shot guideline, may receive upwards of 187.5 micrograms of mercury by their eighth birthday. Although less than the 237.5 micrograms of potential vaccine-mercury exposure by age two, back in the 1990s, the potential—and intentional—prenatal exposure has become higher in the past decade than at any time in history.

I believe you can get vaccines without thimerosal, but you have to ask for them specifically, and you may have to pay more for them.

This is quite the hot-button issue. Suggest that anything about vaccines is not perfect and you're likely to get a bunch of people screaming at you that you're trying to get everyone killed.

Here's a video that shows how researchers are proving it
