Vaccination & Travel: Understanding Illness Rates - Vaccinated vs. Unvaccinated

The exact percentage of vaccinated people who get sick when travelling compared to unvaccinated people may vary depending on multiple factors such as local transmission rates, the level of vaccination coverage in different areas, the efficacy of different vaccines against prevailing variants, traveller behaviour and adherence to preventive measures.

To provide a more accurate comparison, it is crucial to have access to updated and population -based epidemiologic data comparing illness and infection rates, including sever cases and associated risk factors. This information requires ongoing study of surveillance by public health institutions.
