Vaccines can have side effects – truth
Vaccines aren’t risk free. The most common side effects are soreness at the injection site and fever, which are best treated with acetaminophen or ibuprofen. Less common are seizures (defined as “jerking or staring”), and risks vary depending on the vaccine. For example, 1 in 14,000 children suffer a seizure after receiving the DTaP shot; it’s 1 in 3,000 with the MMR vaccine.
Some kids are at higher risk for side effects than others. In these cases, it may be best to proceed with caution or skip them, according the CDC.
