Older persons are more susceptible to infections and have a higher risk of serious complications, with a worse functional and vital prognosis. Vaccination is an effective strategy with a favorable safety profile for preventing infections and promoting healthy aging. In view of the clinical evidence and the vaccines available in Portugal in the first half of 2025, the Geriatrics Study Group of the Portuguese Society of Internal Medicine presents a proposal for vaccination of adults aged 65 years or older. The experts also point out the need to create a national lifelong vaccination program that includes older people to increase vaccination coverage and reduce the impact of infections in this population. Although the document focuses on people aged 65 years or older, vaccination against some diseases should start earlier. This article outlines five main recommendations: 1) Annual influenza and COVID-19 vaccination for all adults aged 50 years or older, with those aged 65 years or older receiving the high-dose trivalent influenza vaccine; 2) Respiratory syncytial virus vaccination for all adults aged 60 years or older and adults aged 18 - 59 years with risk factors, prioritizing people aged 75 years or older and those aged 50 years or older with risk factors; 3) Pneumococcal vaccination with the 20-valent or 21-valent pneumococcal conjugate vaccine for all adults aged 50 years or older and adults aged 18 - 49 years with risk factors; 4) Herpes zoster vaccination with the recombinant vaccine for all adults aged 50 years or older and adults aged 18 - 49 years at high risk of herpes zoster; 5) From the age of 65 years, booster vaccination against tetanus, diphtheria and pertussis every 10 years.
