Sheri Paulson had difficulty getting up a few months after the diagnosis of Covid-19.
The 53-year-old North Dakota resident and her family contracted the disease after attending a wedding in August. Paulson is an endurance athlete who runs a farm on the outskirts of Fargo. Later, she suffered from fatigue, brain fog and rapid heartbeat, which led her doctors to advise her to stop exercising and participate in cardiac rehabilitation.
Paulson, who suffers from multiple sclerosis, said: “Suddenly, I stopped taking naps after the heart recovered.” “Then I started taking the dog for a walk. Then I thought,’Well, I want to Run a little bit.'”
Some people with troubled and often debilitating symptoms months after the first infection with the virus say that after vaccination, confusing health experts are looking for relief. The Survivors Corps is a patient advocacy organization that provides services to people suffering from the so-called Covid disease. It recently surveyed nearly 900 members and found that 41% of them indicated that their full recovery has eased shortly after they were shot.
The World Health Organization estimates that every 10 Covid patients will remain healthy 12 weeks after being infected with the virus. Researchers at the University of Washington released data in February and found that one-third of patients reported persistent symptoms, including fatigue, shortness of breath, and sleep disturbances, which lasted for up to 9 months.
According to public health officials and health experts, long-term Covid symptoms are referred to by researchers as the acute sequelae of Covid-19, or PASC. The symptoms can develop well after the initial infection, and the severity can range from mild to loss. Ability to work.
One of the world’s largest studies published in early January found that many people continue to get sick after being infected, and six months later they will not be able to work at their full capacity. The study surveyed more than 3,700 people aged 18 to 80 from 56 countries.
Diana Berrent founded the Survivor Corps more than a year ago. After months of Covid torture, most of her symptoms resolved spontaneously last year. She said that some members of the organization were reluctant to receive vaccination at first. She said members were concerned that the side effects of these ammunition reportedly would worsen their symptoms.
She told CNBC that the vaccine really “makes us feel the most disgusting.” “When I find that some people are starting to get better, you may be overwhelmed by feathers because it exceeded our expectations.”
They are not alone. Facebook and Twitter are filled with stories of many people who have proved that their symptoms have reduced or disappeared after receiving the Covid vaccine, which surprised them.
do not know much
The cause of persistent symptoms is still not well understood by health experts.
Most research focuses on people with serious or fatal illnesses, not those who have recovered but still report lingering side effects, so-called long-distance travelers. The virus is also relatively new-only discovered more than a year ago-so there is no long-term data.
The National Institutes of Health launched a program in February to study prolonged Covid and find out the cause and potential treatment. Dr. Francis Collins, director of the National Institutes of Health, said at the time that researchers wanted to understand the underlying biological causes of long-term symptoms.
Doctors still don’t know why some patients with Covid-19 say they will feel better after being immunized. Experts say that understanding this may provide new insights behind the persistent symptoms and provide potential new treatments for combating such symptoms.

According to Yale University immunologist Akiko Iwasaki, one theory is that the vaccine helps eliminate the so-called “viral reservoir” in which the virus can still linger and cause chronic symptoms. Scientists who have been engaged in Covid research for a long time said that the strong immune response induced by the vaccine may help eliminate any remaining virus and eliminate symptoms.
She told CNBC in a telephone interview: “This may be the most direct way.” Vaccines can help people. “If this is the case, people will feel cured of the long Covid, which will be good news.”
Iwasaki also hypothesized that Covid may cause autoimmune diseases, in which immune cells mistakenly damage the human body. She said that if this is the case, the vaccine may provide “temporary relief” and the patient may eventually need to be injected again.
She said there are no long-term data on how people feel after being vaccinated. “But I doubt if the second [hypothesis] It’s true, it won’t be long-term relief. “
Darren Brown, a 37-year-old physical therapist in the UK, said that he recovered his symptoms a few weeks after receiving the first dose of Pfizer vaccine.
Brown has been tired for months, disturbed sleep and coordination. He said that about three weeks after his first injection, his prolonged Covid symptoms completely disappeared. But a few days before the second dose, he felt his symptoms began to recover.
He said: “I started to find myself getting more tired again.” I thought I could improve my level, the threshold, it felt as if it had been lowered, after that I had nothing to go back to work, I just need to go to bed. “
He has felt better since the second dose, but he said he was worried that his symptoms might reappear.
He said: “I’m really cautious, thinking it might not last.” “But I’m very at a loss for the excitement of being cancelled now.”
North Dakota farmer Paulson said she still has some symptoms, but since the second shot on March 18, fatigue and brain fog have disappeared. She added that she was very happy that she was doing well, especially because many other people died of the disease.
Paulson said: “There are always things that make you look forward to life and somewhat make you back off.” He also worked for a biotech company in Massachusetts.
Dr. Paul Offit, a voting member of the FDA’s Advisory Committee on Vaccines and Related Biological Products, said that although reports of relief from chronic Covid symptoms may be good news, they are still anecdotal.
He said that formal trials are still needed to determine whether the vaccine is really helpful.
Isaac Bogoch, an infectious disease expert at the University of Toronto, responded to Offit’s speech, saying that he was skeptical but “open-minded.”
Bogqi said: “This is an answerable question, and I hope we have decent data to confirm or refute this.” “Otherwise, this is just a bunch of collective anecdotes.”
Iwasaki told CNBC that she plans to collaborate with Survivor Corps on a study to analyze blood samples from long-term Covid patients before and after vaccination. She said he hoped they could explain the remission of some patients after vaccination.
She said the research is still in the planning stage, adding: “We are working hard to make it work.”
She said: “I have received many emails and DMs about patient experiences on Twitter. I listen to letters from people who feel better after being vaccinated every day.” “From my standpoint, this seems encouraging. .”
