8 common myths about Corona vaccines

There are still questions and concerns about the new emerging coronavirus vaccines, even among those who understand the scientific process, trust medical experts, and know how important vaccines are to combat infectious diseases.

It is natural for people to raise questions, as Dr. Tadeus Stubbenbeck, head of the Division of Infections and Immunology at the Lerner Research Institute of the Cleveland Clinic in the United States asserts, who points out that these vaccines are “new therapies”, considering that “it is perfectly reasonable to ask constructive questions with an open mind in Like it. ”

Quoted from “Sweet siteDr. Stubbenbek raises some common questions, fears and myths that have emerged about Corona vaccines, especially the new generation vaccines based on messenger RNA, seeking to put things into perspective:

Myth 1: Corona vaccines cannot be trusted because they have been expedited

The first vaccines for Corona include a new technology that was developed in record time, but without going through short cuts, as the medical expert asserts, who explains that the new technology inherent in the Corona vaccines produced by “Pfizer” and “Moderna” is called “messenger RNA” messenger RNA, or mRNA. Although this is the first time that this type of vaccine technology has been used on a large scale, researchers have already been working on this vaccine strategy for more than three decades.

Dr. Stubbenbek says: “We were lucky that this technology has undergone a good level of development over the past few years and has been tested in many animal infection models, so we are assured that it is safe. The emergence of the emerging corona virus presented an important opportunity to use this technology, which is The vaccine developers were not prepared for it. ”

The companies subjected their vaccines to rigorous clinical trials in which tens of thousands of volunteers participated. In the United States, the Food and Drug Administration requires companies to follow volunteers for up to two years after receiving vaccinations to ensure they are safe and effective, but due to the extent of the spread of the Corona virus, it took only a few months to conduct clinical trials and collect enough data to make an initial evaluation.

Myth two: The vaccine gives recipients of the emerging corona virus

The head of the Department of Infections and Immunology at the Lerner Research Institute says that vaccines stimulate the immune system to recognize and fight disease, but they do not cause infection.

The “Pfizer” and “Moderna” vaccines contain a strand of genetic material called mRNA. When it enters the cells of a person receiving the vaccine, it directs them to make a piece of the barbed protein on the shell of the emerging virus. These protein pieces do not harm the human body but stimulate the immune system to respond to fight them.

And Dr. Stubbenbek adds that it is normal to feel tiredness, muscle pain, headache or fever after getting the vaccine, which is common with any vaccine, and a sign of the immune system’s response to it.

Myth 3: The contents of vaccines are unknown

“Pfizer” and “Moderna” published lists of ingredients for their vaccines, which, in addition to the most important component, the genetic material mRNA that make up the prickly protein, contain fats that help deliver the genetic material to cells and some other common components that help maintain the pH and stability of the vaccine. Also, both vaccines do not contain microchips or any form of tracking device.

Myth 4: Vaccines will alter the DNA of their recipients

Vaccines use the genetic material mRNA to direct cells to make a piece of the prickly protein characteristic of the Coronavirus in order to stimulate the immune system’s response to the virus if it infects the body. Cells work to break down and dispose of this substance once their directing mission is completed.

“This genetic material is made from messenger RNA, but it is not designed to integrate with human DNA, and it does not cause any change in us or in the genetic map (the human genome) in any way,” Dr. Stubbenbeck explains.

Myth 5: Whoever is infected with the emerging coronavirus will not benefit from the vaccine

The medical expert says: “We do not yet know how long the natural immunity against the Corona virus will last. It appears at the present time that infection with the virus more than once is not a common thing, but there are still many questions without answers. Here, experts say that even if you have) I became infected with the emerging coronavirus, and it will still be appropriate to receive the vaccine, to ensure protection. ”

Myth 6: The high survival rate from the emerging corona virus means that a vaccine is not needed

It is true that most people who contract the virus are able to recover from it, but Dr. Stubbenbek, on the other hand, says that it is also true that some infected people suffer from dangerous complications. So far, nearly two million people have died around the world due to the emerging corona virus, and this does not include people who survived, but who needed to be hospitalized and suffered from a disease capable of causing damage to the lungs, heart and brain, and it may also cause long-term health problems. Experts are still in depth. To know her.

He adds that there is another reason for getting the vaccine, is to “protect those around us. Even if the virus does not make you very sick, you can still pass it on to another person who may become more affected, so the vaccine protects the population at large, including those who are most vulnerable.” For those who cannot be vaccinated, so the vaccine will be important to end the pandemic. ”

Myth 7: Once I get vaccinated, I will not have to wear a mask or worry about physical distancing

Dr. Stubbenbek stresses that it is necessary to continue wearing the muzzle around others, washing hands and practicing physical distancing, even if a person gets the vaccine, explaining that there are good reasons for this, the first of which is that the “Pfizer” and “Moderna” vaccines require two doses, separated by a period of between Three weeks and four to achieve the best possible immunity.

A person does not become immune immediately when he gets the first dose, according to the doctor, as it takes between a week and ten days for the body to start building antibodies, and then these antibodies continue to increase during the following weeks.

The second is that these vaccines were developed and tested on the basis of their ability to prevent severe disease caused by the Coronavirus, and it is not clear yet whether they also protect against infection and spread without symptoms.

“Studies will continue to assess this, but it will take time, which means that after you get the vaccine, you still have to be careful to protect others who have not yet been vaccinated,” says Dr. Stubbenbeck.

Myth 8: After vaccines are found, the pandemic will end very soon

The head of the Division of Infections and Immunology at the Lerner Institute at the Cleveland Clinic asserts that the end of the pandemic and the immediate return of everything to normal is “everyone’s wish,” but he notes that it will in fact “take a long time until we can vaccinate enough people to start seeing the decline in cases injury”.

In order to achieve the so-called herd immunity, that is, the point at which the spread of the disease is likely to stop, about 70 percent of the population will need to be vaccinated with the vaccine or contracted with the virus, according to the expert who concluded: “The production capacity of the pharmaceutical companies producing these vaccines is limited, so the distribution will be made. Vaccines are phased, giving those most in need of priority.
