One of the most selfish and narcissistic tropes of the antivaccination cult is that “if your child is vaccinated why do you need to worry about mine.” Setting aside the fact that the vaccine denier can make that arrogant statement because most of the community is vaccinated so her children are protected by the herd effect, it ignores the fact that not every child is vaccinated.
Children who are under the age of 3-6 months either have not or just received the DTaP vaccine against whooping cough (Bordetella pertussis), so they are susceptible to adults, teenagers and other children who might be passing along the disease. Moreover, vaccines are not 100% effective (this does not mean that they are 0% effective, just that it’s not perfect), so some people may be vaccinated but still can catch the disease.
But there are also children who cannot be vaccinated for medical reasons, and they are vulnerable to infectious diseases, even the flu. In a recent story, the Brisbane Australia Courier Mail reported about a three year child, Lachlan, who, because of a liver transplant that may leave him immunosuppressed for the rest of his life and unable to get vaccinated, must be protected against those children that might carry diseases that could kill this child. To be clear, because vaccine deniers tend to have no knowledge of real science, this child cannot be vaccinated not because the vaccines would harm him, it’s because his immune system cannot develop the adaptive immune response, so the vaccines are useless.
His parents, Chris and Nelia Hay, must be extraordinarily vigilant in protecting young Lachlan. Another child, whose parents may listen to the reprehensible Meryl Dorey, may not be vaccinated and pass along the “harmless measles,” which could kill Lachlan. Every sniffle. Every rash. Anything seen on another child must make the Hays stiffen with fear.
And when Lachlan heads off to a school, his parents will probably have to choose a school with extraordinarily high vaccination rates. Not that I would actually recommend this, but Mississippi, which doesn’t allow any vaccine exemptions except medical ones, has a nearly 99% vaccination rate. Lachlan would be safe there from the ignorance of antivaccination lunatics.
Society and political entities evolved to protect the individual citizen (OK, it’s not perfect, but it’s better than the alternative). We vaccinate not only to protect the ones we love, but also to protect the ones we don’t know. Vaccines work, and we have scientific evidence supporting. Vaccines are safer than almost any medical intervention out there, and we have evidence supporting that. To not vaccinate is simply wrong.
