Vaccination: The bad old days

IMG_4898

Have you ever met anyone who had diphtheria? How about tetanus? You may know an older person who had polio as a child, and most people my age can remember measles and mumps, but how about congenital rubella? Hemophilus influenza meningitis? Smallpox?

As vaccines become more effective, and global vaccine campaigns more successful, fewer and fewer people (let alone their doctors) have any direct experience with the infections we vaccinate against.

That’s why vaccine-preventable infections can be a low priority for some young parents: They’ve never seen any of them. As one dad put it not long ago, when we got onto the subject of polio risks for his two month old daughter: “What’s the point of  getting shots for non-existent diseases? It’s like you’re warning us about the dangers of buggy whips.”

That’s how my days go, sometimes…

I really like the illustration that accompanies this post (and thanks to my daughter Claire for sending it to me). The left hand column of red-tinged syringes shows how many cases of a given infection occurred each year in the pre-vaccine era. The mostly red-free column on the right lists the annual totals we see today.

The differences are dramatic, but it’s important to take note of the little slivers of red still visible next to infections like measles, mumps, and congenital rubella. These diseases and the others on the list aren’t extinct, they’re just held at bay by vaccines (and other public health improvements like clean drinking water and improved hygiene).

So keep this chart in mind when thinking about vaccinations for your child. Oh, and those bad old days? In the case of Hemophilus influenza, they weren’t so long ago: the vaccine didn’t come out until I’d been in practice for several years. I (and my patients) lived those 20,000 cases a year…

Flu shots help prevent preterm birth

5278448067_f76b92377cA research team in Georgia recently published a study that shows the protective effect of flu vaccine for pregnant women.

Led by Dr. Saad Omer of Emory University, the team examined the records of more than 3,300 pregnant women between April 2009 and 2010. They found that those women who received influenza vaccine overall had a 40% lower likelihood of giving birth before 37 weeks of pregnancy than women who were not vaccinated. That protection increased to 72% during the peak of the flu season.

The protection extended to birthweight as well. Vaccinated women were 69% less likely to have a small for gestational age baby than were the unvaccinated women.

Dr. Omer’s study underscores the importance of flu shots for pregnant women. Keep that in mind come next October, when the 2013-2014 vaccine  comes out!
