Research on COVID 19 vax causing Essential Thrombocythemia?

I had ET three years before covid and vaccines. I have had 5 Pfizer covid vaccines so far, didn't seem to change my platelet counts.

@mdterp76 & @annettezam Here is where to report suspected vaccine reactions: https://vaers.hhs.gov/reportevent.html

The more information you can provide, the better. The batch number for each Covid vaccine you received is on the card you were given.

Many things can cause a DNA error. A biology textbook could tell you more, but I think that mutations can be caused by certain chemicals, ionizing radiation, and just accidents during DNA replication caused by atoms jiggling around at random.

Life is so complex and subtle that I don't ask how things can go wrong; I ask how is it possible that anything ever goes right? Life, from molecules, to cells, to tissues, organs, organisms, and whole ecosystems, operating across timespans of billions of years, is amazing.

I agree. I developed Essential Thrombocythemia AFTER my Vaccine Shots TM Retired MD

Recently dx with non hodgkins lymphoma follicular type.
I have done some research regarding covid vaccines & covid virus and continue to educate myself with with studies on pubmd. I acquired the delta virus with bad results & have never felt the same since. Now with my NHL dx it is very suspicious.
I have been in a long covid 19 study @ UPMC Pittsburgh for one year and so far the only person with lymphoma.

Just clarification: elevated platelets higher than 400 is not necessarily ET. In fact, elevated platelets aka secondary thrombocytosis is a symptom of many other illnesses, many of them treatable/curable. True essential thrombocytosis (caused by one of three known MPN mutations and identifiable in the bone marrow by malformed nuclei in blood cells) is fairly rare.

In typical cases of true ET, the mutation lurks for many years before it shows elevated blood counts in a lab test.

So the questions that might deserve study for patients who fear that the covid vax has caused their ET:

Could covid vaccines cause elevated platelets that return to normal as vax wears off?

Could the vaccines hasten platelet proliferation in those with an ET mutation who are not registering elevated platelets?

Is the vax causing an ET mutation and more rapid disease progression (mutation followed by platelet proliferation in weeks vs years)?

I'm grateful for vaccines and boosters. ET patients who take HU are immune compromised and more likely to get vivid. ET patients who get covid are more likely to develop fatal clotting and pulmonary failure. Those are facts. Reports about a vax-ET connection are speculation.

I also agree. I had the first 2 shots and tested for RA. Both of my hands swelled up so bad I couldn’t open a water bottle. When I finally got in to see an RA physician and she reran the tests they came back negative. After physical therapy and taking tumeric they are much better.
Now my platelets are in the 500’s and I was diagnosed with ET. Didn’t have any issues until the vaccines.

Memorial Sloan-Kettering discusses whether the covid vaxxes can cause cancer.

Mayo also discusses links between vaxxes and other diseases.

Well, I had ET long before COVID vaccines were even thought about. I have had five, both Pfizer and Moderna, all of those in my eighties! I did not need COVID messing up my life.
The lucky ones who got the vaccine, when suggested, have likely saved many from COVID. I think with any disease, there are always possible odd side effects or unusual and largely unknown reasons for other complications. Vaccines have been around to protect from many, many illnesses. Polio, measles, and so on that have maimed and killed people in the past. Unfortunately, the ‘squeaky people’ against vaccines seem to get all the media coverage.

I don't think anyone knows the real truth about why this happened but we just don't want it to happen again. TM MD
