According to CDC, after a vaccine is authorized or approved for use, many vaccine safety monitoring systems watch for adverse events (possible side effects). This continued monitoring can pick up on adverse events that may not have been seen in clinical trials. If an unexpected adverse event is seen, experts quickly study it further to assess whether it is a true safety concern. Experts then decide whether changes are needed in U.S. vaccine recommendations. This monitoring is critical to help ensure that the benefits continue to outweigh the risks for people who receive vaccines.
Easier global travel will become a reality with one or more COVID-19 vaccines being available before the end of 2020. Before you travel, you’ll need to be tested, and when the vaccines are available, you’ll need to get vaccinated. The IHAWO provides a platform for you to register and receive proof of your negative COVID-19 test and vaccination with the certificate stamp on your VAX Passbook.
