Childhood vaccinations can save lives

The benefits of the shots vastly outweigh their risks

Published: August 2012

Back to school is a good time to check up on the vaccines your children need. In fact, many schools won't allow students to enroll or participate in sports unless you can show that their shots are up to date.

Unfortunately, no kid likes shots. And some parents remain uncertain about the safety and effectiveness of childhood vaccines. In fact, at one point or another a small but vocal group of skeptics have blamed vaccines for everything from attention deficit hyperactivity disorder and autism to brain damage and multiple sclerosis.

But many well-designed scientific studies have found that such blame is misplaced. And for all of the vaccines listed in the table below, the benefits vastly outweigh the risks, and in many cases can protect your child from potentially deadly diseases.

Reactions in the first days after a vaccination can include a sore arm, fever, aches, and pains, but these are minor, usually well-tolerated, and resolve quickly. A more serious reaction can occur, usually after four or more weeks, but it's rare. For example, the risk of brain inflammation after a measles vaccination is one in a million. But the risk after natural infection with the measles virus is much greater—about one in 1,000 cases.

So during your next office visit, ask your doctor what, if any, shots or boosters your child needs. (And ask about vaccines for adults, too.)


Who should get it

• Children who aren’t fully vaccinated and never had chicken pox should receive one or two doses.

• Older children who aren’t fully vaccinated and never had chicken pox should receive one or two doses. Timing of those doses depends on the child’s age.Timing of those doses depends on the child’s age

• All children. First dose should be at 2 months (five doses total). 

• DTaP is not licensed for people 7 or older. A single dose of a similar vaccine, Tdap, is recommended for people ages 11 to 64.

• Children who are not vaccinated by 2 years old can be vaccinated later.
