COVID-19 Vaccination Guidelines for Older Adults

Rationale for Vaccination

The National Comprehensive Cancer Network (NCCN) recommends COVID-19 vaccination for all persons regardless of prior COVID-19 infection, as vaccination provides additional protection beyond natural immunity 1
Elderly individuals (>65 years old) are at significantly higher risk of COVID-19-related hospitalization, ICU admission, and mortality due to comorbidities, poor nutrition, depressed immunity, and lower organ function 2
Vaccination after natural infection enhances immunity and provides more robust protection against variants that may evade natural immunity alone 2

For individuals who have recently had COVID-19 infection, it is recommended to postpone vaccination for 2-3 months after infection 3
Waiting this period allows the immune system to recover and may enhance the vaccine response while reducing the risk of adverse effects, such as injection site pain, fatigue, myalgia, headache, and fever, which are generally mild to moderate (grade 1 or 2) 3
