A VAERS ID consists of seven numbers followed by '-1': 1234567-1.
Since all VAERS IDs end with '-1', you may omit that from IDs entered here: 1234567.
Please note that some VAERS IDs start with '0': 0012345-1.
The VAERS ID length increased in the data released in CDC WONDER on 2/12/2021,
due to the total number of events reported. Older VAERS IDs with less than 7 numbers now start
with a zero. For example, 0123456
replaces 123456.
