In most cases, vaccination helps to prevent serious illness. However, in rare instances, a vaccine can cause a serious injury. One injury that can result from a vaccine is optic neuritis, an eye injury.
Shoulder pain after receiving a vaccine in your arm is quite common. However, this pain typically lasts only a short time. If your shoulder pain lasts long after you received a vaccine, you may have a shoulder injury related to vaccine administration, which is commonly referred to as SIRVA.
The flu vaccine helps to prevent the spread of influenza, which leads to nearly 30,000 deaths each year. However, the flu vaccine comes with its own risks, especially for older adults.
