The flu shot is safe for senior citizens and other adults, excluding those who have experienced a severe allergic reaction to a previous flu vaccine. People who are allergic to eggs should seek medical advice before getting a flu shot.
The immune system begins to weaken for people age 65 years and older; therefore, it is important for senior citizens to receive a vaccine to prevent the flu and stop symptoms from spreading. Vaccination options include the regular-dose flu shot and high-dose flu shot. The high-dose shot helps boost the immune system's response. Seniors citizens are at a higher risk of developing pneumonia from the flu and have the choice of getting the pneumococcal vaccine.
