The use of effective vaccines against the predominant SARS-CoV-2 virus variants and the extent of the immune response (waning immunity) are key aspects to try to protect better the high-risk populations. Updated vaccines are currently swiftly available. However, the number of people vaccinated with any additional booster dose is declining. Improved health information and training for health care professionals, together with the use of better tools to make simpler vaccination recommendations, can encourage higher vaccination rates. Addressing these challenges is essential to improve vaccination coverage and ensure adequate protection in the face of evolving COVID-19 threats.

The Omicron variant prevailed for nearly 2 years and now several of its subvariants like JN.1, KP.2, or XEC are or can be the dominant ones.

RSV-related ARIs significantly affect the relevant clinical outcomes, including hospitalization and mortality, in older adults. Elderly individuals and those with chronic diseases are at a higher risk of infections with severe morbidity because of clinical frailty and deficiencies in immune responses. Prevention of respiratory viral infections in the adult population can be achieved through hygiene measures and active immunization. Several vaccination strategies have been developed, including nucleic acid, subunit, chimeric, live-attenuated, particle-based, and recombinant vaccines, with varying results. Subunit vaccines involving the RSV-fusion protein F in its prefusional (pre-F) conformation, with or without adjuvants, have demonstrated significant protection in older adults, reducing the rate of total and severe RSV-related lower tract respiratory diseases (LRTDs). Similarly, an mRNA vaccine encoding for the stabilized pre-F conformation showed a significantly reduced RSV-associated LRTDs in older adults. This evidence led to recent approval of two subunit vaccines (Arexvy and Abrysvo) and one nucleic acid-based vaccine (mResvia) by regulatory authorities. Currently, several vaccines are recommended for adults, resulting in crowded schedules. Therefore, covaccination is a potential strategy for improving vaccine adherence.
