A viral illness spread through close skin-to-skin contact, often during sex. CDC advises vaccination for travellers anticipating new sexual partners or exposure at large public events in at-risk regions.
Dosing & timing
Two doses 4 weeks apart (JYNNEOS). Best protection is about 2 weeks after the second dose — ideally start 6 weeks before travel. Evidence suggests protection lasts at least 7 years; no booster needed.
