The reporting requirements for COVID-19 vaccines are the same for those authorized under emergency use or fully approved. Healthcare providers who administer COVID-19 vaccines are required by law to report to VAERS the following after vaccination:
Vaccine administration errors, whether or not associated with an adverse event (AE):
If the incorrect mRNA COVID-19 vaccine product was inadvertently administered for a second dose in a 2-dose series, VAERS reporting is required.
If a different product from the primary series is inadvertently administered for the additional or booster (third dose), VAERS reporting is required.
VAERS reporting is not required for the following situations:
If a mixed series is given intentionally (e.g., due to hypersensitivity to a vaccine ingredient)
Mixing and matching of booster doses (as of October 21, 2021, mixing and matching of booster doses is allowed)
Serious AEs regardless of causality. Serious AEs per FDA are defined as:
Death
A life-threatening AE
Inpatient hospitalization or prolongation of existing hospitalization
A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions
A congenital anomaly/birth defect
An important medical event that based on appropriate medical judgement may jeopardize the individual and may require medical or surgical intervention to prevent one of the outcomes listed above
Cases of Multisystem Inflammatory Syndrome
Cases of COVID-19 that result in hospitalization or death
Healthcare providers are encouraged to report to VAERS any additional clinically significant AEs following vaccination, even if they are not sure whether vaccination caused the event.
Also, healthcare providers should report any additional selected AEs and/or any revised safety reporting requirements per FDA’s conditions of authorized use of vaccine(s) throughout the duration of any COVID-19 vaccine’s Emergency Use Authorization (EUA) or any approved COVID-19 vaccine as outlined in the Fact Sheet for Healthcare Providers.
If a 93-year-old man who was diagnosed with CHF five years ago dies after getting the vaccine, his doctor has to report it. Even if he would have died anyway.
An 88-year-old nursing home patient suffers a stroke after being vaccinated. The nursing home must report it, even if the patient was at high risk for stroke before the vaccine.
An 86-year-old patient has a sore arm and feels so shaky and fatigued she mostly stays in bed for four days after vaccination, unable to go to the dining room and attend her usual activities. The nursing home reports it. (The vaccine may well have caused it.)
A 47-year-old woman is diagnosed with acute kidney failure after getting the vaccine. Her doctor must report it, regardless of his opinion on the cause.
Most reports are submitted by healthcare providers based on a doctor’s diagnosis or observation and therefore do not need to be verified. Reports submitted by private individuals would either be too mild to require serious medical attention — or they would be duplicate reports, as the healthcare provider would have submitted a report as well, as required by law. There is a system in place to weed out duplicates.
