Dr. Sanjay Gupta notes that vaccines have prevented 6 million deaths every year worldwide

"The benefit of vaccines is not a matter of opinion," he writes. "It is a matter of fact"

CNN  — 

I have started, scratched out and even abandoned the writing of this essay. I couldn’t do it. It wasn’t there. Didn’t feel it.

Something kept nagging at me, and it took some time to finally figure out what it was.

It’s the idea that this article would be labeled “opinion” or “editorial” in the first place.

Sure, there are some topics that seem to lend themselves appropriately to opinion pages. Vaccines, however, which have prevented 6 million deaths every year worldwide and have fundamentally changed modern medicine, should not be on that list.

The benefit of vaccines is not a matter of opinion. It is a matter of fact.

Studies, including a meta analysis of 1.2 million children in 2014, show no link between vaccines and autism. That is not a matter of opinion. It is a matter of fact.

That you are 100 times more likely to be struck by lightning than to have a serious allergic reaction to the vaccine that protects you against measles is not a matter of opinion. That is also a matter of fact.

Facts should matter, and science should win, but after 13 years as a medical reporter, I know it is not that simple.

Science often loses the zeal argument to ideology, and in some ways, it is easy to understand why.

At the heart of the vaccine argument is the awesome challenge of trying to prove a negative.

If you or your child never gets the disease the vaccine was designed to prevent, there is no surprise. There is no headline. Life goes on.

The flip side, though, is the one-in-a-million child (literally, 1/1,000,000) who has a serious adverse reaction. It is likely to make the news, confirm the worst fears and lead to the enlistment of an army in the fight against vaccines.

It is worth pointing out that 12 out of 10,000 people who take an aspirin are at risk of intracerebral hemorrhage, or bleeding in the brain. People who regularly take too much acetaminophen are the largest group of people hospitalized for acute liver failure. And, on average, one person in the United States dies every year from H20 intoxication, or drinking too much water. And yet no armies have formed against aspirin, Tylenol or water.

David Katz, director of the Yale University Yale-Griffin Prevention Research Center, wrote that it makes no more sense to rant against vaccines because you heard of someone who might have had an adverse reaction than to stop walking because you heard about a pedestrian struck by a car.

In many ways, it is a luxury to be able to have this discussion at all.

Having spent time in West Africa covering the Ebola outbreak, I saw how people hoped, wished and prayed for a vaccine – to no avail.

On the other hand, the measles vaccine is readily available, and yet vaccination rates in certain areas of the United States are similar to the refugee camps I have visited in Haiti, Pakistan and Jordan.

Yes, parents have a choice in this country.

It is a choice that so many others around the world will never have.

Of course I vaccinated my children. Didn’t think twice. Not a big fan of the measles or mumps or rubella – to name a few very preventable diseases.

And here is where I may lapse for a moment into opinion.

    The anti-vaccination argument is often snugly wrapped in the “I love my kids” sentiment. And I find it, well, a little insulting.

    To suggest that anyone who vaccinates their kids doesn’t love them is a whole new level of lunacy. But here is the fact of the matter, for me.

    It’s not just because I love my kids that I vaccinated them. It’s because I love your kids as well.
