Dr. Eric Gordon and Dr. Nafysa Parpia presented today at the .lyme 2026 European Scientific Conference in London. This is one of the few gatherings that brings together Lyme-literate physicians from across the globe who are actively working at the intersection of tick-borne illness, post-infectious disease, and complex multi-system chronic illness, and the level of clinical rigor in that room reflects where this field is heading.
Grateful to be in a room full of physicians who are asking the same questions we are.

Dr. Eric Gordon and Dr. Nafysa Parpia are in London tomorrow, presenting at the .lyme 2026 European Scientific Conference. The conference brings together physicians from across the globe who are actively working on the diagnosis and treatment of tick-borne illness and complex multi-system disease. It is one of the few gatherings where the clinical realities of Lyme disease and post-infectious illness are taken seriously at a research and treatment level, and where the physicians in the room are pushing those conversations forward.

For people with healthy immune systems who tolerate vaccines without issue, this may prove to be a reasonable option as the long-term data continues to develop.
The re-engineering does appear to have addressed the joint-related autoimmune concerns associated with the original design, and that is worth noting. What is still missing is a complete long-term safety timeline, clarity on the annual dosing schedule going forward, and sufficient follow-up data for the populations most at risk. For patients managing complex chronic illness, that gap matters. Dr. Gordon's position is clear: watch how the data develops, and do not move faster than the evidence.

Two injections per year, with no confirmed answer yet on whether that schedule continues annually, and that is where the conversation becomes more clinically significant.
Vaccines that work through a similar mechanism tend to produce strong initial immune responses that wane relatively quickly, which may explain the two-dose annual structure. The deeper concern, however, is immunological. Patients most vulnerable to persistent Lyme disease tend to share a common pattern, where the innate immune system has difficulty downregulating. That same pattern is what makes repeated vaccine exposure more complex in this population. The concern is not an acute reaction, it is whether repeated exposures have cumulative effects on immune function in people whose systems are already under strain.
Part 3 drops tomorrow.

A new Lyme vaccine is expected to release later this year or early next, and while some are encouraged by the updated design, the clinical picture is not yet complete.
The new vaccine uses the same Borrelia antigen as its predecessor, which signals the immune system to respond to the bacteria, but it has been re-engineered to reduce cross-reactivity with joint proteins, which was a central concern with the original. Phase three trials have just wrapped, and while that is a milestone worth noting, the study size and follow-up period are not long enough to confirm whether autoimmune and joint-related risks have been fully ruled out. The engineering is more refined, and there are still open questions that time and data will need to answer.
Follow along this week as Dr. Gordon shares his full clinical perspective on the new Lyme vaccine in this 3 part series.

Mast cell activation syndrome develops for a reason. There is often an insult to a tissue rich in mast cells, whether the gut, nervous system, brain, vascular space, skin, or even bone. Combined with pre-existing factors like genetics or prior infections, the mast cells become primed for overreaction.
It does not happen randomly. An insult occurs, the body responds, and in some patients that response never turns off. Identifying the original trigger, or the factors keeping the system activated, is part of understanding why MCAS developed in the first place.

She received her undergraduate degree in Chemistry and earned her doctorate from the National University of Natural Medicine in Portland, Oregon in 2003. Her focus was primary care with three years in midwifery before moving to California in 2012, where she joined a clinic focused on chronic complex illness.
Dr. Sugden is well versed in infertility, prenatal care, and postnatal care and how these may relate to Lyme and tickborne illness. In 21 years of practice, she has never seen two cases that were the same, even with the same diagnosis. Each patient walks their own unique path, and it is only through truly listening that she can understand the details of that path and help support them forward.

Spring is here and as you step outside, ticks are already active. A tick bite does not necessarily mean an infection was transmitted, but knowing what to do and when to test can help you stay ahead of potential complications.
If you do not save the tick, timing matters for testing. Antibody tests are more reliable about three weeks after the bite, as your immune system needs time to respond. PCR tests, which look for bacterial DNA, are more likely to detect infection during the first week or two. There are many opinions on when and how to treat, and consulting a Lyme literate practitioner is the best way to discuss the safest option for you.
Early treatment can make a big difference in long-term health. Save and share this post for tick season.

In the early phases of Lyme, it is primarily an infection issue. If you can catch it within the first year or treat it at the time of exposure, the focus is on addressing the bacteria. The longer it goes on, the picture changes.
Chronic Lyme is not always driven by the infection itself. Over time, it creates the conditions for immune dysregulation, and that becomes the bigger problem. Predisposing factors like genetics, toxic burden, or previous infections can also play a role in how the immune system responds.
This is why treatment for someone who just got bit looks very different from treatment for someone who has been sick for years.
