Sheri Paulson had trouble getting out of bed months after her Covid-19 diagnosis.
The 53-year-old North Dakota resident and her family fell ill after attending a wedding in August. Paulson, an endurance athlete who later worked on a farm outside Fargo suffered from fatigue, brain fog, and elevated heart rate, which led doctors to advise her to stop exercising and Get heart therapy
Less than five days after she fired her first Pfizer in February, she started to feel better.
“Suddenly I was no longer taking a nap after cardiac therapy,” says Paulson, who suffers from multiple sclerosis. “And then I started walking with my dog. ̵6;Hmm, I think I’ll run a bit too.’ ”
Some people who had been suffering from sluggish and often debilitating symptoms for months after their first battle with the virus said they were relieved after being vaccinated. Another health expert, Survivor Corps, a patient advocacy group for people called the long-lived Covid, recently surveyed nearly 900 members and found 41% of them reported little relief to fully recover shortly after.

The World Health Organization estimates that about 1 in 10 people with COVID-19 will develop sustained illness 12 weeks after being exposed to the virus. Researchers at the University of Washington published data in February found that one in three patients reported ongoing symptoms, including fatigue, shortness of breath and sleep disorders, which persisted for up to nine months.
The symptoms of COVID-19, which researchers call the Post-Acute Sequelae of Covid-19, or PASC, can develop well after initial infection, and the severity can range from mild to incapacitating, according to public health officials and experts. Says health
One of the largest global studies published in early January found that many people who continued to contract sickness after being infected were unable to return to work to their full potential six months later. The study surveyed more than 3,700 people aged 18 to 80 from 56 countries.
Diana Berrent, the founder of Survivor Corps last year, suffered from long-lasting COVID for months before most of her symptoms were resolved last year. She said some members of the organization were initially very reluctant to get vaccinated, she said, fearing members.Berrent said reported shooting side effects would worsen symptoms.
“We really expect the worst,” she told CNBC in a phone interview. “You might just knock me down with a feather when I find some people getting better because it’s out of what we expected.”
They’re not alone. Facebook and Twitter are full of stories from people who witnessed amazement that their symptoms subsided or disappeared after receiving the Covid-19 vaccine.
Don’t understand well
The cause of ongoing symptoms is not well understood by immunologists and other healthcare professionals.
Most of the studies focused on people with severe or life-threatening illnesses, not those who had recovered. But the side effects still persist, known as hikers The virus is relatively new, discovered a little over a year ago, so no long-term information is available.
The National Institutes of Health in February initiated a long program of COVID studies and identified possible causes and treatments for individuals, NIH Director Dr. Francis Collins said at the time, researchers. Hope to understand the underlying biological causes of prolonged symptoms.
Doctors do not yet know why some patients with COVID say they feel better after being vaccinated. Experts say that finding it can provide new insights into what’s behind the symptoms, as well as potential new treatments to combat it.

One theory, according to Yale immunologist Akiko Iwasaki, is that the vaccine eliminates so-called “viral reservoirs” where the virus may remain in the body and cause chronic symptoms. The strong immune response induced by the vaccine may clear residual virus and eliminate symptoms, said scientists who are studying long-term COVID.
“That’s probably the most straightforward solution,” the vaccine can help people, she told CNBC in a phone interview. “If so, people will be fully cured from COVID, and that will be good news.”
Iwasaki also hypothesized that COVID may cause an autoimmune disease in which immune cells inadvertently destroy the body. If so, the vaccine may be given. “Temporary relief” from symptoms and eventually the patient may need to come back on medication, she said.
There’s no long-term information on how people feel after getting the vaccine, she says, “but I wonder if the second [hypothesis] As a matter of fact, it will not be relieved for a long time. “
Darren Brown, a 37-year-old physical therapist from the United Kingdom, said his condition returned a few weeks after he received the first Pfizer vaccine.
For months, Brown experienced fatigue, insomnia, and impaired coordination. He said he felt his long-term coronavirus had completely improved about three weeks after he received his first shot. But just days before the second dose, he felt his symptoms started to return.
“I started to notice that I was getting tired again,” he said. “The level where I thought I could push myself, the threshold felt lower and I had nothing in me after that. Back to work, I have to go to bed after a long day at work. “
He felt better since taking the second medicine. But he said he was concerned that his condition might return.
“I was very careful that this might not last,” he said, “but I am also very excited that it has now been lifted.”
Paulson, a Naan of North Dakota, said she still had some symptoms. But the fatigue and brain fog has gone missing since being filmed for the second time on March 18, she added that she is grateful for doing well, especially since so many others have died from the disease.
“There are a lot of things that give you perspective in life and require you to take a step back,” said Paulson, who works for a biotech company in Massachusetts.
While reports of prolonged relief from COVID may be good news. But it’s still just an anecdote. Said Paul Office, a voter member of the FDA’s Committee on Vaccines and Related Biological Products.
Formal trials are still needed to determine if the vaccine really helps, he said.
Isaac Bogoch, an infectious disease expert at the University of Toronto, echoed Offit’s speech, saying he was skeptical but “generous.”
“This is an answerable question, and I hope we have good information that can confirm or refute it,” Bogoch said.
Iwasaki told CNBC that she plans to conduct a study in collaboration with Survivor Corps, analyzing long-term blood samples of COVID-treated patients before and after vaccination. She said he hoped they would be able to explain some of the relief to some patients after vaccination.
The study is still in the planning stages, she said, adding: “We are working hard to be able to do this”
“I get a lot of emails and DMs on Twitter about my patients’ experiences … and I hear every day from people who feel better from getting vaccinated,” she says.
