Research on COVID 19 vax causing Essential Thrombocythemia?

My thought is that there is no known connection between ET and the covid vaccine at this time. None. There is no evidence that the covid vax triggers abnormally high platelet levels.

The covid vaccine has a mRNA fragment that triggers our immune system to that piece in a covid virus, which is how the vaccine ramps up our antibodies to attack the nasty virus. A poor analogy is chocolate chip ice cream; the chips (mRNA) are part of the ice cream, but you won't get brain freeze from eating a chip. Could the vaccine ramp up your immune system to go after other things? Shingles is from the Chicken Pox herpes virus; if you have had it then the virus is dormant in your body. It can be reactivated by stress or illness. So, it might be good to make sure your Shingles and other vaccinations are up to date. The covid vaccine doesn't prevent covid, it decreases your chance of getting it and the severity if you do. Covid mutates too quickly to completely corral it. Things that don't mutate, like measles and polio, could be erradicated if enough people were vaccinated.

I had my first of 6 covid vaccines in 2021...my plts started trending up since then. started around 450, last one was 606 ..I feel like there is correlation with vaccine and thrombocythemia.

I never thought about it but my playlets have been increasing even with taking hydroxyurea. Conincidence maybe?

Maybe ask yr oncologist about this?

A 150 point platelet rise over three years sounds pretty normal for someone with ET, especially if you aren't on hydroxyurea or need your dose adjusted. I went from 600s to 800s from age 60 to 63. This was pre covid, so I know it wasn't the vaccine.

I was only on aspirin at the time, and once I hit 800, I went on HU.

It's the nature of ET for platelets to keep proliferating to higher and higher levels unless treated. Basically that's why it's classified as a cancer by WHO.

My platelets started rising right after my first 2 shots. I developed Essential Thrombocytosis with CALR exon 9 mutation and now have to take hydroxyurea.

There is a direct correlation to the shots. Whether the WHO will admit it, is another question.

I was diagnosed with T Cell LGL Leukemia right after having COVID pneumonia. The doctors at Mayo said that there are not enough studies whether it caused it or not. I think that they all say the same thing. Good Luck to you.

I had the same issue. My platelet count started at 400 and started rising after I had the covid shot. I also tested positive for RA after I had the vaccine. After seeing an RASpecialist and more tests which came back negative for RA, my platelets started rising, and have continued to do so. I tested positive for Et jak2 mutation. My last count was 601. I am only taking a low dose aspirin for now.
I am 78, and feeling good which is why I don’t want to go on any medication. I only had the first two shots, and will never have another one.

IMHO, measles and polio and very different from Covid.
The first two had been identified in a lab and the vaccines developed from that showed a dramatic decrease in new cases of measles and polio. Like my friends, I got both of those vax as a child and never got measles or polio.
Many friends who got the C-vax still got very sick with it, some got sick several times. While anecdotal, this tells me it doesn’t work as advertised. Certainly not the way measles and polio vax work. What no one is saying is what else does the C-vax do to a body? I hope someone is collecting data.

I also had a nasty reaction to the covid vaccines, but it was a lot better than if I had gotten covid. I'd rather have my wonky immune system ramp up than get extremely ill. I'm old enough that I had measles. Most vaccines in "the old days" were based on weakened bacteria or virus that couldn't infect us. The mRNA vaccines are proteins or other pieces of the bacteria or virus that are used to trigger our immune systems to attack the "real" invaders. There is a lot of research now on covid and associated reactions to infection, and vaccines. There is also a huge amount of misinformation on it (vaccines do not cause autism, bleach and dewormer don't work). Research takes time, which occurs during and following the pandemic. Some people refused the covid vaccine because "it came out too soon" (but after millions worldwide had already died), however, the vaccine was based on decades of genetic research and collaboration across countries. Are there a lot of unknowns about covid and the vaccine? Of course.
