The answer is the vaccine for Moderna, as the company said yesterday, Monday, at the JP Morgan Healthcare Conference, that the immunity provided by its vaccine against “Covid-19” should last at least a year. According to what was quoted Reuters.
The drug company said that it is confident that the messenger RNA technology it used was well suited to deploy a vaccine based on a new variant of the Coronavirus that has appeared in a number of countries.
The name of the Corona vaccine from Moderna is “mRNA-1273” (mRNA-1273), and it uses artificial messenger RNA to mimic the surface of the Corona virus and teach the immune system to recognize and neutralize it.
Moderna said last December that it would conduct tests to ensure the effectiveness of the vaccine against any strain.
The company announced yesterday that it expects to deliver between 600 million doses and one billion doses of its vaccine in 2021, and expected vaccine sales of $ 11.7 billion this year, based on previous purchase agreements signed with governments.
“The team feels very comfortable with the track record we have now … We are on the right track to provide at least 600 million doses,” said CEO Stefan Bancel.
The response to 8 common myths about mRNA-based coronavirus vaccines
From this good news, we turn to refuting myths and concerns about the new emerging coronavirus vaccines based on messenger RNA technology, such as the Moderna vaccine.
Naturally, questions arise among people, as Dr. Tadeus Stubbenbeck, chief of the Department of Infections and Immunology at the Lerner Research Institute-Cleveland Clinic in the United States asserts, who points out that these vaccines are “new treatments and It is perfectly reasonable to ask constructive and open-minded questions about them. “
In statements to the German News Agency, Dr.Stubbenbek raises some common questions, concerns and myths that have emerged regarding 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 it was expedited
The first vaccines for Corona include a new technology that was developed in record time, but without going through shortcuts, as asserts a medical expert who explains that the new technology inherent in the Corona vaccines, produced by both “Pfizer” and “Moderna” It is called messenger RNA. Although this is the first time that this type of vaccine technology has been used on a large scale, researchers have already worked on this vaccine strategy for more than 3 decades.
“We were lucky that this technology has undergone a good level of development during the past few years and has been tested in a number of models of infection in animals, so we are assured that it is safe,” said Dr. Stubbenbeck. This technology is what vaccine developers were ready for. “
The companies subjected their vaccines to rigorous clinical trials in which tens of thousands of volunteers participated. The Food and Drug Administration in the United States requires companies to follow volunteers for a period of two years after receiving vaccinations to ensure that they are safe and effective, but given the extent of the spread of the Corona virus, it took only a few months to implement clinical trials and collect enough data to conduct an evaluation. first.
Myth two: The vaccine is transmitted to 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” vaccine contains a strand of genetic material. 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 rather stimulate the immune system to respond to fight them.
And Dr. Stubbenbek adds that it is normal to feel fatigue, 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” have published lists of the components of 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 preserve On the degree of acidity of the vaccine and its stability. Also, both vaccines do not contain microchips or any form of tracking device.
Myth 4: Vaccines will change 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, and the cells work to break down this material and get rid of it as soon as it completes its guiding mission.
Dr. Stubbenbek explains that this genetic material is made of messenger RNA, but it is not designed to integrate with human DNA, and it does not cause any change in the human or the genetic map (the human genome) in any way.
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 natural immunity against the Corona virus will last, and it seems at the present time that infection with the virus more than once is not common, but there are still many questions without answers.”
And here, experts say that even if you have contracted the emerging coronavirus, it will still be appropriate to get 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 of those 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 around the world have died due to the emerging corona virus, and this does not include people who survived after they needed to be hospitalized and suffered from disease capable of causing damage to the lungs, heart and brain, and it may also cause long-term health problems The experts are still delving into her knowledge.
He adds that there is another reason pushing to get the vaccine, which 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, from Among them are those most at risk who cannot be vaccinated, and therefore 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 the need to continue wearing the muzzle while you are close to 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 obtaining Two doses, 3 to 4 weeks apart, 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 from a week to 10 days for the body to start building antibodies, and then these antibodies continue to increase during the following weeks.
Also, 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,” said Dr. Stubbenbeck.
Myth eight: After vaccines are found, the pandemic will end very soon
The head of the Department of Infections and Immunology at the Lerner Institute at the Cleveland Clinic affirms that the end of the pandemic and the immediate return of everything to normal “is everyone’s wish,” but indicates that in fact it “will take a long time until we can vaccinate enough people to start seeing Decrease in incidence. ”
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% of the population will need to be vaccinated with the vaccine or infected with the virus, according to the expert who concluded that “the productive capacity of the pharmaceutical companies that manufacture these vaccines is limited,” Therefore, vaccines will be distributed in stages, and those who need them most will be given priority in that. ”
