“VigiAccess was launched by the World Health Organization (WHO) in 2015 to provide public access to information in VigiBase, the WHO global database of reported potential side effects of medicinal products.

Special note regarding COVID-19 vaccine data: To see VigiBase data on COVID-19 vaccines, search for “covid-19 vaccine”. Please note that VigiAccess, as a result of the terminology used to structure the information, will group the data for vaccines by disease (for example, “Measles vaccine”, “Mumps vaccine”). This means that even searches for exact tradenames, such as “Comirnaty” or “Covishield”, will result in the total number of cases reported for all COVID-19 vaccines. It is not possible in VigiAccess to separate the numbers for specific vaccines.
