What you're committing is the ad hominem fallacy.
Finding some malefactors who vaccinate doesn't
mean that vaccines aren't valuable.
Anti-vaxers have many evil death dealers who
convince the gullible to take their untested potions
by pretending that vaccines are ineffective & even
dangerous.
Excerpted...
The nation’s
oldest anti-vaccine advocacy group often emphasizes that it is supported primarily by small donations and concerned parents, describing its founder as the leader of a “national, grass roots movement.”
But over the past decade a single donor has contributed more than $2.9 million to the National Vaccine Information Center, accounting for about 40 percent of the organization’s funding, according to the most recent available tax records. That donor, osteopathic physician Joseph Mercola, has amassed a fortune selling natural health products, court records show, including vitamin supplements, some of which he claims are alternatives to vaccines.
In recent years, the center has been at the forefront of a movement that has led some parents to forgo or delay immunizing their children against vaccine-preventable diseases such as
measles. Health officials say falling vaccination rates contributed to the infectious virus
sickening more than 1,200 people in the United States this year, the largest number in more than 25 years. Measles outbreaks are
surging worldwide, including in Samoa — where
nearly 80 people have died since mid-October, an ad hom because the great majority of them young children and infants.
