Reason # 1 Why vaccine reactions vary, say doctors

This is why the side effects of Covid vaccine go from one person to another.


As the deployment of the Covid vaccine continues across the country, you probably noticed howdifferently, people reacted to their shotsThey are manufactured by Johnson & Johnson, Pfizer-Biontech or Moderna. Some people have side effects that stuck them in bed for a day or two and others seem to beLive nothing at all. So, what does it mean if you are at one end of the spectrum or somewhere in the middle? Continue reading for the main reason for recipient vaccine reactions and for more vaccinals,This side effect of vaccine could mean that you already had Covid, a new study says.

Different immune systems are the main reason for different vaccine reactions, doctors say.

In an article for the conversation,Robert Finberg, MD, aprofessor of medicine At the University of Massachusetts Medical School, explains that yourThe body develops two responses to a vaccine: The initial response is called the innate immune response, but it is the subsequent answer, called the adaptive immune response, helps you protect yourself if you come into contact with the virus later. "The sustainable adaptive immune response ... rests on the T and B cells of the immune system that learn to recognize particular invaders, such as a coronavirus protein. If the environnement is encountered again, months or even years at the 'Future is these immune cells that will recognize the old enemy and will begin to generate the antibodies that will flow, "he explains.

As for how your body develops these T and B cells,Mark Loafman, MD, told NBC 5 Chicago recently that vaccine reactions are "really just a sort of reflection of how each of our systems is unique". "Each of ourimmune systems is a mosaic composite of everything we have crossed and all we have and we have recently done business, "he explained." Our individual response varies. Everyone gets the appropriate immune response. "

And for more advice on the vaccine,There is a chance of 50 percent chances that you will make this mistake when it is vaccinated.

Several factors play a role in the immune response of your body, including genetics.

Chris Thompson, MD, Immunologist and Associate Professor of Biology at Loyola University Maryland, told holy peopleReact differently to vaccines For a variety of reasons. He stated that factors such as health, genetics, nutrition, age, gender, pre-existing immunity, the environment and the use of anti-inflammatory drugs can all be related to vaccine reactions. "Even if you do not feel defended after your vaccines, it is likely that your body always has a good protective immune response," Thompson explained.

A 2013 study published in the scientific journalCell found evidence that suggestsGenetics plays a role in the immune response of our body. The researchers examined about 8.2 million genes variants in blood samples of 1,629 people in Sardinia, Italy. Sardinia's researchers have found 89 independent gene variants and 53 sites related to the regulation of immune system cell production."From this study, we wanted to know the extent to which the relative immune resistance or sensitivity to the disease is inherited in families, "said:David Schlessinger, PhD, a study author and head of the genetic laboratory at the National Institute of Aging (NIA). "If your mother is rarely sick, for example, does it mean that you do not have to worry about the bug that's going on? Is it an immunity in the genes? According to our conclusions, the answer is yes, at least in part. "

The severity of your side effects does not indicate your level of immunity.

mostCommon side effectsThe Covid vaccine of pain, redness and swelling of the injection site, fatigue, headaches, muscle pain throughout the body, chills, fever and nausea, According to disease control and prevention centers (CDC). But if you encounter any of these side effects slightly or all severely, it does not mean that the vaccine has aggravated or better.Anna Wald, MD, a doctor of infectious diseases, recently said to Huffpost that the effectiveness of the vaccine is "unlikely to determine byWhat is the severity of your side effects, "The point of sale has reported.

In its article for the conversation, Finberg wrote: "Scientists have not identified any relationship between the initial inflammatory reaction and the long-term response that causes protection. There is no scientific evidence that someone withmore obvious side effects of the vaccineis then better protected from Covid-19. And there is no reason to have an exaggerated innate answer would make your adaptive answer better. "

And for more the reason some people are struck more difficult by the side effects of the vaccine, checkThat's why half of people have lighter vaccine side effects, says CDC.

And a lack of reaction to Covid vaccine does not mean that it did not work.

By responding to a Q & A with Cleveland.com,Amy ray, MD, a metrohealth director, said people should not "use thepresence or absence of side effects as "proof" of immunity. "" If you do not have any side effects, it does not mean that your immune system does not work, "James Fernandez, MD, an expert in allergy and immunology, told the press. "I would not focus on these early side effects related to the vaccine to judge if you have had an [effective] answer or not."

Kelly Elterman, MD, a certified anesthesiologist of the board in San Antonio, Texas, also explained in a recent article for Goodrxlack of side effects did not correlate with a decrease in immunity. "Only about 50% of people vaccinated with Pfizer or Moderna vaccines have been victims of side effects other than arm pains, while 95% were protected from CVIV-19 infection," wrote Elterman. In addition, less than half of Johnson & Johnson recipientsDeveloped side effects Other than pain at the injection site ", up to 74% were protected from CVIV-19 infection."

And if you are curious to know how long your vaccine works,Dr. Fauci says that your Covid vaccine protects you for this long.
