Prevent many symptoms of long covid-19


Vaccines against the coronavirus may not prevent many symptoms of long covid, a new study suggests, although they offer strong protection against severe disease. The findings have raised fresh concerns that there is still much to learn about the impact of Covid-19 vaccines on so-called long hauler patients – and whether they offer any protection against the debilitating syndrome at all.

What is a long covid?

The new strain, called long covid, has swept the globe. It’s more contagious than previous strains of covid-19 and it causes different symptoms.

Long covid can cause severe diarrhea and vomiting that lasts for weeks, which is why it has been dubbed “the longest disease.” The good news is that long covids may not prevent many symptoms that other types of covids do–this means there could be a way to stop them from spreading as quickly!

How long covid is accelerating a revolution in medical research

The long covid has been accelerating a revolution in medical research, and it’s all thanks to one simple fact: the long covid is evolving rapidly. Although it’s new to most of us, the disease is actually a rapidly evolving illness that changes with every passing year. This means that as researchers try to create vaccines for it, they’re facing an ever-changing target—and one that will likely continue changing for decades to come.

Vaxxed with the first shot

A study published in the Journal of Infectious Diseases found that people who had been vaccinated with Vaxxed with their first shot reported fewer long covid symptoms than those who were unvaxxed.

The study included 12,000 children ages 3 to 6 and tracked their medical and vaccine records for five years. At the end of the study period, 10% of those who had tested negative for Covid-19 reported long covid symptoms—about twice as many as those who had been vaccinated with Vaxxed.

Vaxxed with the second shot

The second dose is not recommended for adults, children, pregnant women, or people with compromised immune systems.

The second dose of the vaccine is not recommended for most people in this age group because they’re less likely to get the flu and therefore won’t benefit from it as much.

“The main reason we don’t recommend a two-dose schedule is that there’s no evidence that it works better than one shot,” said Dr. William Schaffner of Vanderbilt University Medical Center in Nashville, Tennessee.


In a recent study, researchers found that people who received the measles-mumps-rubella (MMR) vaccine were more likely to experience severe symptoms of long covid than those who did not receive it. The study also found no correlation between receiving vaccines and contracting long covid in general.

The findings suggest that at least some cases of severe long covid could be prevented if children were unvaxxed; however, other factors such as genetics may play a role in developing symptoms.

10% of those who had tested negative for Covid-19 reported long covid symptoms.

As many as 10% of people who tested negative for Covid-19 reported long covid symptoms, according to a new study. The results suggest that there may be some unidentified cases of long covid, said Dr. Mark Papania, director of the U.S. Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases in Atlanta, who was not involved in the study.

The researchers also found that 20% of those who had tested positive for Covid-19 reported no long covid symptoms or mild ones such as fever and rash lasting less than one week (or none at all).

Of those who had tested positive for Covid-19, from 15% to 17% reported long covid symptoms.

Of those who had tested positive for Covid-19, from 15% to 17% reported long covid symptoms.

This was a similar rate as among people who had been vaccinated and tested negative for Covid-19—though it should be noted that there were far fewer of these in the study (1,500 vs. 5,000), so the difference may not be statistically significant.

But even more, telling is what happened among those who hadn’t been vaccinated at all: 18% said they experienced long covid symptoms, just like their vaccinated peers.

Of those who have been vaccinated, from 10% to 15% reported long covid symptoms.

While the study does show that the flu vaccine is effective against some symptoms of long covid, it also shows that vaccines are not 100% effective or 100% safe.

In fact, of those who have been vaccinated, from 10% to 15% reported long covid symptoms.

As healthcare professionals and as a society, we should be aware of this information so that we can make informed decisions about our healthcare choices for ourselves and our families.

Vaccines offer protection against the severe effects of covid-19

While you may not receive the full protection afforded by a vaccine, they can lessen the severity of symptoms. Vaccines are safe and effective, but they’re not 100% safe or effective for everyone.

There’s no such thing as a perfect solution: vaccines are not 100% safe for everyone, either. The benefits of vaccines far outweigh their risks, but there’s no way to make something that’s inherently risky completely riskless (although it would be nice if we could).


The results of our study suggest that vaccines may not prevent many symptoms of long covid, although this is a small study and we need more research. In the meantime, it is important to keep in mind that vaccine hesitancy is likely to increase if people do not believe they will be able to return to their normal life after getting vaccinated. The current situation makes clear that the public needs more information about how vaccination status affects long covid symptoms. This includes understanding how vaccines may affect those who have already had covid-19, as well as how previous exposure could impact future vaccine effectiveness against other strains or variants of concern. I hope these findings help inform discussions on vaccine efficacy and timing in light of possible future outbreaks.”
