For most people, vaccination is a safe, standard procedure that will prevent more serious illnesses from affecting them. Unfortunately, vaccines are not 100% safe for all people.
Even healthy people could be negatively affected by vaccines or face complications from getting one. In fact, there are some rare complications that patients should know about before they get vaccinated. Knowing about the risks helps them be informed and make the best decisions for their own health.
What are the major complications that vaccines can cause?
All vaccines have a potential to cause complications. Here are five of the most common complications that could happen.
- Infection at the injection site
If you get an injection, then that needle has to enter your skin. It may go into your soft tissues, a vein or muscle, depending on the kind of vaccine it is. That injection site needs to be kept clean, and the needle used should be sterile. If not, an infection could occur, which may lead to sepsis or other illnesses.
Some people are allergic to the contents of vaccines. It may not be possible to know about that allergy until the vaccine is administered, which is why they should be given in a medical setting with a waiting period after the injection.
- Blood clots
Some vaccines have the potential to cause unusual blood clotting, which could lead to serious injury or death without treatment.
- Overactive immune response
Some people have immune systems that overreact to vaccinations. This may lead to unusual lymph node swelling or extreme fatigue. High fevers, too, are possible with an overactive immune response.
- Guillain-Barré Syndrome
According to the Centers for Disease Control and Prevention, Guillain-Barré Syndrome, or GBS, is possible after some vaccinations (particularly those for influenza). There is no known cause of GBS, but the illness leads the immune system to damage the nerve cells. This sometimes leads to paralysis and muscle weakness.
Vaccines do have real side effects. Though there are benefits to the vaccinations, it’s important to know that these vaccination complications could occur. Patients should always be informed about the risks and should look into their legal rights if they are injured.
