State health officials have contacted some New Hampshire residents to confirm the information on their vaccine cards.
The calls were made due to potential data entry errors in about 0.6% of vaccine records, and contact was made to fix people's information in VINI, New Hampshire's online vaccine registration system, a spokesperson for the state said.
The errors were due to incomplete information provided during initial registration, mismatches in dose formulation, or incorrect lot numbers for administered vaccines.
If you're wondering whether a call you recieved is valid, the state encourages anyone who is worried to dial 211 and ask to speak with individuals making outbound calls.
