Do Vaccines have side effects?


Any medication can cause minor side effects and vaccines are no different (2). However, it does not make them any less safe. Vaccines are safe and their side effects are usually minor as well as temporary (3). Vaccines may cause low grade fever, pain or redness at the site of injection, or a rash. Even slight discomfort is normal (2). While rare, sever or long lasting side effects are extremely rare (1).


Vaccines are safe. Any licensed vaccine is rigorously tested across multiple trials phases before being approved for use. After being approved they are regularly monitored and assessed. Scientist are also constantly monitoring information for signs that the vaccine is causing a health risk (2). If your child does have a serious reaction, then you should call your doctor immediately. Make sure to write down what happened, along with the date and time that it occurred. Then ask your doctor to file a VAERS, or a Vaccine Adverse Event Reporting System (1).


If a vaccine is suspected to have a problem, then a thorough investigation will take place. During an investigation they will thoroughly examine the case which reported the problem, which includes a medical assessment, and if needed studies are conducted (4). However, during these investigations it is extremely rare that the health problem was caused by the vaccine. Instead health events are usually found to be coincidental and unrelated to the vaccine (4). Other times though it could be to how the vaccine has been stored, transported or administered and can be prevented in the future by proper training, and improving vaccination programs. There are rare cases where a genuine adverse reaction is suspected from a vaccine. In these cases, further investigation will happen in order to determine the cause in order to correct it (4).  


Keep in mind that a person is more likely to be hurt by a vaccine preventable disease than the vaccine that protects them. Many vaccine preventable disease may result in death without being vaccinated. Therefore, the benefits of being vaccinated vastly outweigh the risks that come with not being vaccinated (3).
