Choose the shingles vaccine to protect against symptoms and complications from herpes zoster infection, even if you've already had shingles.

The burning or tingling pain from the shingles rash can interfere with daily life. If the rash is near the eye, it can lead to vision loss or blindness.

For some people, the pain from shingles continues after the rash goes away. This long-lasting pain is a condition called postherpetic neuralgia. It may last for months or longer. The pain can be sharp, or the area may feel itchy or numb. Postherpetic neuralgia can lead to problems sleeping, distress and a lower quality of life.

Shingles vaccine recommendations vary by country. But in many places, including the United States, health experts recommend people age 50 and older get the shingles vaccine. The vaccine also may be recommended for adults who have weakened immune systems.

The shingles vaccine is not a live virus vaccine. It's made from only part of the virus. The vaccine is given in two doses. The second shot is given 2 to 6 months after the first.

The most common side effects of the shingles vaccine are pain and swelling at the injection site. The area around the injection site may change color. This change may be a shade of red, purple or brown depending on your skin color. Some people also experience fatigue, headache and other side effects.

If you're allergic to any vaccine ingredients or take some medicines, talk with your healthcare professional about the vaccine. Also, if you are planning to be pregnant or are pregnant, talk to your healthcare team before getting the vaccine.

Some people get shingles even with the vaccine. But the vaccine may make the illness milder and help it clear up faster. The shingles vaccine has been shown to protect against shingles for at least 10 years.
