The Role of Inflammation in Long COVID and Post Vax Problems

Long COVID sufferers and people experiencing long term health challenges following vaccine administration present with similar symptoms which suggests a similar mechanism.

In the following video* and blog post the role of inflammation is discussed in the mechanism of Long COVID and post vax problems.

*This video has focussed on discussing underlying factors which may have contributed to dysfunctional immune responses to either the vaccine or infection based on understanding at the time of filming. However, some evidence has suggested that these two phenomena may not be exclusively one-off events for some individuals as discussed in the video. Research has revealed that the spike protein can persist in some individuals for as long as 15 months which may, therefore, elicit ongoing immune responses and contribute to health challenges alongside underyling factors.

Why Some People May Experience Long-Term Symptoms After Infection or Vaccination

Over recent years many people have developed ongoing health challenges following COVID-19 infection or after an adverse reaction to vaccination. What is particularly interesting is that, although these events are different in nature, the people who seek help for these issues often present in very similar ways.

Common symptoms include significant fatigue, brain fog and other cognitive difficulties, neurological and sensory problems, dysautonomia symptoms such as palpitations, cold intolerance and shortness of breath, as well as histamine-type and MCAS-type reactions.

Both COVID-19 infection and vaccination act as inflammatory triggers, since they stimulate the immune system to become more active. For most people this response is temporary and well-regulated. However, in some individuals the immune and inflammatory reaction becomes overwhelming and leads to longer-lasting effects. In addition, emerging studies suggest that spike protein from vaccination may persist in the body far longer than initially expected, which could continue stimulating the immune system beyond the immediate post-vaccination period. Research has detected SARS-CoV-2 spike protein in circulating immune cells or tissues many months after vaccination, and in some cases up to around 15 months or more, even when active virus is no longer present, which may contribute to ongoing immune activation and symptoms in a subset of individuals.

How Inflammation Can Become Overwhelming

During infection with SARS-CoV-2 the immune system is activated to protect the body, which naturally increases inflammatory signalling. Complications such as severe COVID-19 or Long COVID are more likely in people who experience an excessive inflammatory response.

Vaccination also works by stimulating the immune system, and some degree of inflammation is a normal part of that immune activation. However, in a small number of cases, people experience long-term symptoms following what should have been a one-off immune event.

A consistent pattern is emerging among these individuals. Firstly, many have a pre-existing background of chronic inflammation before the triggering event occurred. Secondly, they have a reduced capacity to cope with additional inflammatory load. When another strong inflammatory trigger is introduced, the body becomes overwhelmed, the immune response becomes dysregulated, and collateral tissue stress increases, leading to persistent symptoms.

When the Body Cannot Contain Inflammation

Inflammation itself is not harmful — it is an essential part of healing and immune defence. Problems arise when the body lacks the antioxidant capacity needed to regulate and contain the inflammatory cycle.

When antioxidant reserves are insufficient, excess inflammation leads to greater tissue stress, which in turn produces even more inflammation. Over time this can result in widespread immune activation, mitochondrial dysfunction, and increased vulnerability in sensitive tissues such as the brainstem, thyroid, and nervous system. The body’s stress-coping systems, such as the adrenal response, may also become depleted.

Many people who develop long-term symptoms appear to have both:

• underlying chronic inflammation, and

• a reduced ability to manage further inflammatory stress

Factors That May Contribute to Underlying Inflammation

Across many cases, several recurring contributors to pre-existing inflammation can be seen.

Genetics

Some individuals have a genetic tendency to produce stronger inflammatory responses or may have an increased predisposition toward autoimmune-type reactions.

Toxins and Environmental Load

A number of people show evidence of high toxic burden, including exposure to environmental pollutants, heavy metals, or mould-related toxins. These factors can maintain immune imbalance and make the system more reactive to new inflammatory triggers.

Diet and Modern Eating Patterns

Typical Western diets often contain high levels of omega-6 rich foods, trans fats, and highly processed products. These dietary patterns can encourage stronger inflammatory responses when the immune system is stimulated.

Chronic or Latent Infections

Underlying viral, yeast, or fungal overgrowth — such as Epstein-Barr Virus, herpes-type viruses, or candida — may be present in the background. When the immune system becomes overwhelmed, its ability to keep these under control can decline, allowing them to reactivate and add further strain.

Trauma and Stress

Ongoing stress or unresolved trauma is increasingly recognised as a physiological influence, capable of contributing to chronic inflammatory states within the body.

Why Some People Have Reduced Capacity to Cope With Inflammation

In addition to underlying inflammatory load, many people also have a diminished ability to regulate inflammation once it occurs.

Key contributors include:

Genetic Differences in Antioxidant Production

Some people are less efficient at producing important antioxidant systems such as glutathione, which plays a major role in controlling inflammatory processes.

Limited Antioxidant Intake From Food

A lack of dietary diversity and low intake of colourful, nutrient-rich foods can reduce antioxidant availability and resilience.

Poor Sleep and Low Melatonin

Melatonin is not only essential for sleep, it is also a powerful antioxidant. Poor sleep reduces melatonin levels and has been shown to lower glutathione, further decreasing the body’s ability to regulate inflammation.

Ongoing Inflammatory Drain

When inflammation is already present in the background, antioxidant reserves are continually used up. If another strong inflammatory event occurs, there may be little capacity left to contain it.

Making Sense of Why Long-Term Symptoms Develop

When we look at COVID-19 infection or vaccination simply as inflammatory triggers, the question becomes less about the event itself, and more about why some people were unable to recover from it in the way others did.

By viewing the situation through the lens of:

• underlying chronic inflammation, and

• reduced antioxidant and regulatory capacity

we can begin to understand why a subset of individuals progress into chronic illness rather than returning to baseline health.

This comes with the caveat of potential spike persistence which has the potential to contribute to ongoing immune activation along with other underlying factors. There remains many questions in this area. Why has spike protein persisted in some individuals? Has this happened in every person after vaccination? If so, not all of those have become sick which again suggests that other factors are contributing.

A Pathway Toward Recovery

Once the underlying reasons for this vulnerability are identified, it becomes possible to develop a step-by-step plan aimed at reducing the factors that continue to drive inflammation forward.

The original triggering event — infection or vaccination — was a single moment in time. However, I often find in clinical practise that it is the ongoing contributors that tend to maintain the heightened immune activity, hyper-inflammatory cycles, and in some cases possible autoimmune-type responses.

Spike persistence appears to be a legitimate thing, however, people remain sick for much longer than the suggested potential of 15 months of persistance. With these cases I often find other factors remain to be present which maintain immune dysfunction which spike protein may have also contributed to before finally being cleared.

The body has an inherent capacity to heal, regulate, and move back toward balance when the obstacles to recovery are gradually removed. By addressing the factors that are perpetuating inflammation, many people can begin to restore resilience and improve over time.
