Management of Side Effects in the Elderly After Influenza Vaccination

Common Side Effects and Their Management

The Centers for Disease Control and Prevention recommends that management of local reactions after influenza vaccination should focus on symptomatic treatment with cold compresses and acetaminophen, while monitoring for rare but serious adverse events that require medical attention, in a population of elderly individuals, such as a 93-year-old patient 1
Pain, redness, and swelling at the injection site are the most common side effects, affecting 10-64% of patients and typically lasting less than 2 days, according to the MMWR Recommendations and Reports 2, 1
The American College of Physicians suggests that management of local reactions includes applying cold compresses to reduce pain and swelling, resting the affected arm but maintaining gentle movement to prevent stiffness, and using acetaminophen for pain relief if needed, in elderly patients 1
Systemic reactions, such as fever, malaise, myalgia, and other symptoms, may occur, beginning 6-12 hours after vaccination and persisting for 1-2 days, with a strength of evidence rated as moderate, according to the MMWR Recommendations and Reports 3, 4
The American Academy of Family Physicians recommends that management of systemic reactions includes acetaminophen for fever and discomfort, adequate hydration, and rest as needed, in elderly patients 1

Coincidental respiratory illness may be mistaken for vaccine side effects, according to the MMWR Recommendations and Reports, with a strength of evidence rated as high 2

Immediate medical attention is required for signs of allergic reactions, such as hives, angioedema, and respiratory distress, as recommended by the MMWR Recommendations and Reports, with a strength of evidence rated as high 3, 2
The American College of Emergency Physicians suggests that immediate medical attention is also required for persistent high fever, severe swelling extending beyond the injection site, and symptoms persisting beyond 2-3 days, in elderly patients 1

The influenza vaccine contains only noninfectious killed viruses and cannot cause influenza, as stated by the MMWR Recommendations and Reports, with a strength of evidence rated as high 3, 2
The Centers for Disease Control and Prevention recommends that patients be informed that the benefits of vaccination in preventing influenza and its complications far outweigh the potential risks of mild side effects, especially in the elderly, with a strength of evidence rated as high 6

The American Academy of Family Physicians suggests that mistaking normal local reactions for infection or allergic reactions should be avoided, in elderly patients 1
The American College of Physicians recommends that using antibiotics for inflammatory local reactions should be avoided, in elderly patients 1

The MMWR Recommendations and Reports suggests that for the elderly, especially those over 90, more careful monitoring may be warranted due to potential for decreased physiological reserve, possible comorbidities, and higher risk of dehydration if systemic symptoms occur, with a strength of evidence rated as moderate 4, 1
