If you travel to places with a lot of virus circulating or spend time with people who do, consider getting tested and following prevention steps, even if you are vaccinated. Travelers should follow the guidelines of the state or country they visit. These rules may be different state by state or country by country. Be sure to carry your COVID-19 vaccination card with you in case a business or venue asks to see it. See how to get a copy of your vaccine record and how to get a new vaccine card.
