Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

Do Vaccine Side Effects Go Away?

Analysis of recovery status in VAERS reports. The majority of adverse events resolve, but understanding what "not recovered" means requires important context.

38.5%
of reports indicate recovery from the adverse event (964,443 of 2,508,101 reports with known status)

Why Recovery Data Matters

Recovery status is one of the most commonly cited — and most commonly misunderstood — fields in VAERS. Anti-vaccine advocates sometimes highlight the "not recovered" count as evidence of permanent vaccine damage. This analysis provides the context needed to understand what these numbers actually represent.

Understanding Recovery Status

VAERS tracks whether people recover from reported adverse events, but this data comes with important caveats that are essential for correct interpretation. The recovery field is one of the most frequently misrepresented aspects of VAERS data.

Of 2,508,101 reports with recovery status information:

  • Recovered (Y): 964,443 (38.5%) — the person recovered from the reported adverse event
  • Not recovered (N): 575,989 (23.0%) — symptoms were ongoing at the time the report was filed (see context below)
  • Unknown (U): 967,669 (38.6%) — recovery status was not provided or follow-up was not available

However, "not recovered" doesn't necessarily mean permanent injury. It often means the condition was ongoing at the time the report was filed, which could be days, weeks, or months after vaccination.

The Follow-Up Gap

A key limitation of VAERS recovery data is that reporters are not required to submit updates. Someone who reports "not recovered" on day 3 and then fully recovers by day 7 will permanently show as "not recovered" in the database unless they voluntarily submit a follow-up report — which most people do not do.

What "Not Recovered" Really Means

The "not recovered" category includes several scenarios:

  • Ongoing at time of report: Symptoms that hadn't resolved when the report was submitted
  • Chronic conditions: Pre-existing conditions that may have been exacerbated
  • Incomplete information: Cases where follow-up information wasn't available
  • Permanent sequelae: True permanent effects (the minority of cases)

Importantly, VAERS is a passive surveillance system. Many people who recover completely may never submit follow-up information to update their recovery status.

COVID-19 Vaccine Recovery Patterns

For COVID-19 vaccines, 29.8% of reports indicate recovery, with 32.8% listed as not recovered. This pattern is similar to other vaccines and likely reflects the high volume of COVID-19 vaccine reports and the various types of symptoms reported.

Many COVID-19 vaccine "not recovered" reports involve common symptoms like fatigue or headache that were ongoing when the report was filed, rather than permanent disabilities.

Vaccines with Higher Non-Recovery Rates

Some vaccines show higher rates of "not recovered" status, but this often reflects the nature of the population receiving them or the types of symptoms commonly reported:

  • LYME: 48.3% not recovered (1,132 of 2,344 reports)
  • PNC21: 38.7% not recovered (571 of 1,474 reports)
  • UNK: 32.8% not recovered (9,417 of 28,738 reports)
  • COVID19: 32.8% not recovered (352,659 of 1,076,320 reports)
  • PNC20: 30.4% not recovered (2,100 of 6,918 reports)

These differences may reflect various factors including the age and health status of recipients, the types of adverse events commonly reported for each vaccine, and reporting patterns rather than inherent differences in recovery likelihood.

The Reporting Timeline Factor

A critical limitation is timing. VAERS reports are often filed shortly after vaccination when symptoms first appear. If someone experiences fatigue for a week after vaccination, they might report "not recovered" on day 3, even though they fully recover by day 7.

Unlike controlled clinical studies, VAERS doesn't systematically follow up with reporters to update recovery status. This creates a bias toward "not recovered" classifications for conditions that would eventually resolve.

Recovery by Symptom Type

Recovery rates also vary significantly by the type of adverse event reported:

  • Local reactions (injection site pain, swelling): near-universal recovery within days, though often not updated in VAERS because reporters consider them trivial
  • Systemic reactions (fever, fatigue, headache): typically resolve within 1–3 days; high recovery rates in clinical trial data
  • Allergic reactions (anaphylaxis, urticaria): most recover fully with treatment, though some may have lingering anxiety about future vaccinations
  • Neurological events (GBS, Bell's palsy): recovery rates vary; GBS patients typically improve over weeks to months, with most regaining full function
  • Cardiac events (myocarditis): vaccine-associated myocarditis shows favorable recovery, with most patients having normal cardiac function at follow-up

What Families Should Know

If you or a family member experiences an adverse event after vaccination:

  • Seek medical attention for any concerning symptoms, especially chest pain, difficulty breathing, severe allergic reactions, or neurological changes
  • Most common side effects (soreness, fever, fatigue) resolve within 48 hours
  • Report the event to VAERS at vaers.hhs.gov — this helps monitor vaccine safety
  • Discuss future vaccination plans with your healthcare provider

Clinical Context

Clinical trials and active surveillance studies generally show higher recovery rates than VAERS suggests. For example:

  • Most injection site reactions resolve within 1-3 days
  • Systemic symptoms like fever and fatigue typically last 1-2 days
  • Even more serious events like myocarditis often have good outcomes with treatment

The controlled environment of clinical trials allows for better tracking of symptom resolution compared to the voluntary, passive VAERS system.

Active surveillance comparison: The CDC's V-safe program, which actively followed up with COVID-19 vaccine recipients via smartphone, found that the vast majority of reported side effects resolved within 7 days. V-safe data consistently shows higher recovery rates than VAERS because it systematically checks in with participants, capturing resolution that VAERS misses. This reinforces that VAERS "not recovered" rates are inflated by the lack of follow-up, not by genuinely poor recovery outcomes.

Key Takeaways

  • 1.38.5% of VAERS reports with known status indicate recovery
  • 2."Not recovered" often means "ongoing at time of report" rather than permanent injury
  • 3.VAERS lacks systematic follow-up, creating bias toward "not recovered" classifications
  • 4.Clinical studies show higher recovery rates than suggested by VAERS data alone

Frequently Asked Questions

If someone doesn't recover, does that mean permanent injury?
Usually not. "Not recovered" in VAERS most often means symptoms were ongoing when the report was filed. Many people recover after their report is submitted but never update VAERS. True permanent injuries from vaccines are rare.
Can VAERS recovery data be updated?
Yes, but updates are voluntary and infrequent. VAERS allows follow-up reports, but most reporters do not submit them. This creates a systematic bias toward "not recovered" in the data.
Where can I find more reliable recovery data?
Clinical trials and active surveillance systems (like V-safe and VSD) provide more accurate recovery information because they systematically follow up with participants. These consistently show higher recovery rates than VAERS suggests.
