COVID-19 Vaccines and Fever: Scientists Have Discovered a New Potential Link

COVID-19 Vaccine Coronavirus Vaccination

mRNA COVID-19 vaccines are a type of vaccine that uses a small piece of the virus’s genetic material, called messenger RNA (mRNA), to help the body’s immune system recognize and fight the virus that causes COVID-19. mRNA vaccines have been shown to be effective at preventing COVID-19 infection and have been authorized for use by regulatory agencies around the world.

There has been some concern about the side effects of mRNA COVID-19 vaccines, such as fever and fatigue, which are generally considered normal and transient. However, the relationship between these adverse reactions and antibody production after receiving the vaccine has not been thoroughly studied.

A team of researchers from Okayama University recently conducted a study to examine this link. They recruited 49 university staff and students who had not previously had COVID-19 and found that there is a relationship between the incidence of fever and antibody counts, particularly after the third dose of the vaccine. Their findings were published in the Journal of Epidemiology.

mRNA vaccines mimic the surface structure of SARS-CoV-2 in the body. These are then recognized as invading pathogens by immune cells, which create antibodies against them. As a result, antibody counts may be used to quantify the immune system’s response to vaccination.

Increase in Antibody (IgG) Levels Over One Week After the Third mRNA 1273 Dose in the Fever and Nonfever Groups

All subjects were surveyed for adverse reactions a week after they received the third mRNA-1273 vaccine dose. Simultaneously, antibody levels of all subjects were measured just before receiving the vaccine, 3 days after, ~1 week after, and finally 1 month after the dose. Using statistical modeling, correlations between the incidence of fever and antibody levels at various time points were stipulated. To account for factors contributing to the onset of fever post-vaccination, the team also looked at sex, age differences, a history of allergy, and the use of antipyretics (fever-reducing drugs) amongst the participants.

The subjects were then classified into a “fever” or “non-fever” group based on the survey results. It was found that the fever group was more likely to be younger (20 to 49 years old) and had a past history of allergies. Next, antibody levels at different time points in the two groups were analyzed. At 1 week post-vaccination, the fever group had substantially higher antibody counts than the non-fever group. However, at 1-month post-vaccination there seemed to be no correlation between the incidence of fever and high antibody levels.

This is the first study to highlight associations between the induction of fever and antibody levels at various time points after the third dose of the mRNA-1273 vaccine. “Antibody titers after mRNA-1273 vaccination may be faster in the group with post-vaccination fever, but the difference may not be significant 1-month post-vaccination,” concludes the team. The researchers also suggest that while these contradictory observations may not have significant clinical relevance, a study with a larger sample size might provide better insights.

  1. This is a load of crap. You make me sick. Why don’t you just post the pictures of you suking Big Pharma’s Dik. They are all going to be hanged. Do you want to hang with them?

  2. Shown to be effective at preventing infection… In manufacturer backed studies, real world evidence is lacking. Uses a small piece of virus genetic material makes them sound like an actual vaccines. What this should say is uses RNA instructions to make human cells replicate spike proteins to help the body recognize spike proteins which has proven to be far less effective as traditional vaccines that use an inactive part of virus to teach the immune system. The wording here is intentionally misleading.

  3. Hey, let’s conduct and publish a study of fever, fatigue and antibody counts of people who have received the Covid injections.

    This hasn’t been done because honest researchers are busy studying the mind-boggling numbers of disabling and fatal side effects suffered by people who got these injections.

    If we hyped this enough, it might distract people from the serious damage. It’s a long shot, but at sentencing hearings it might at least look like we did something to look for after effects.

  4. It doesn’t really matter if the shots are killers or miracle drugs. Censorship made voluntary informed consent impossible, so every injection site is a crime scene and every injector a criminal.

  5. Health care ?? NO, WHO cares.
    And WHO is as CORRUPT + as $CUMMY as the VIRULENT 3,O00?WALKING DEAD DISEASES that infect a small european town annually to vomit their venomous ‘agenda’ to make the ‘superfluous life’ vanish

  6. … and an effective therapy against covid instead of a serum called vaccine is…?
    Still waiting for an answer in Canada under a dictator referred to as little potatoe.

  7. I’ve read the comments. You should disable comments.

  8. I’ve never seen anything in my life that was so filled with mistrust lies in manipulation in my life..
    I will never trust any of these shots big farma The politicians or any of the officials involved whatsoever ever again..

  9. Grateful I refused the shot no matter what (manipulation was SO obvious) but now I’m horrified that I may outlive my whole family, dad to grown sons. Fauci lied.
