At many hospitals, the number of patients reported to have post-vaccine injuries rose fivefold or more after Covid vaccines were introduced in December 2020, medical records databases show.
For example, one database including 100 institutions included more than 8900 reports in 2021, compared to fewer than 2000 in 2019 and 2020. A different system reported an increase from 162 in 2019 to more than 1100 in 2021.
Several people with access to different databases provided the figures, on the condition that they remain anonymous, as the databases are proprietary and confidential. All the databases showed a similar increase, ranging from four-fold to more than 10-fold.
