Dr. Simidchiev has revealed the 10 myths about COVID-19 vaccines

Even with the start of mass vaccination in our country, long queues of people who want to be vaccinated against COVID-19 have formed in front of parts of the country. Despite the serious influx of people who want to protect themselves from the coronavirus, however, many questions remain in society, some of which are still absurd, related to the risks of dose injection. That’s why Monitor asked for answers to the 10 most common myths about vaccination on social media. The answers to these questions for our readers are given by the leading pulmonologist Dr. Alexander Simidchiev.

Myth 1: Vaccines are dangerous to our health and can make us sick / cause a severe allergic reaction:

Each approved vaccine goes through a very strict regulatory process that evaluates safety, efficacy and quality. As vaccines are mainly intended for healthy people, the safety requirements are particularly high. Allergic reactions are possible, but most of the time they are not directly due to the vaccines, but can occur either due to the production technology (eg chicken egg residues in vaccines technologically made in chicken embryos) or latex from the cap of the vial that stores the vaccine. In general, global and national allergy companies accept that vaccines have a perfectly acceptable safety profile and that it is very rare for an individual to be released due to an allergy.

Myth 2: There are “second quality” vaccines / vaccines that protect less than others:

Each vaccine has a set of characteristics that distinguish it from another biological product with a similar mechanism of action. It must be evaluated as a whole and not on the basis of an isolated quality. If we cultivate safety, we can only prefer vaccines without effectiveness, only on the basis of “good” safety. In the latter cases discussed, a vaccine has a more moderate degree of protection against a mild illness, but substantially the same degree of protection against serious illness and hospitalization. At the same time, it can be prescribed by doctors, while others can not. This vaccine is not “second quality”, but it is suitable in cases where we want doctors to vaccinate.

Myth 3: After getting vaccinated I get infected:

Unless the vaccine is a live virus, vaccines that are currently being developed cannot be infected with the vaccine because it contains only a small portion of the virus. The reason masked people are also required to wear masks is because if the virus enters the airways, they can sneeze and infect others for a while, but only for a very short time before the virus, which can not multiplied in the vaccinated person, I get lost.

Myth 4: Vaccines can cause permanent damage, including to the cardiovascular, nervous and sexual systems, and lead to infertility:

The vast amount of data already collected from both clinical vaccine trials and their widespread use (already over 215 million vaccinated with at least one dose and over 40 million with full course) do not confirm such concerns. Vaccines for KOVID-19 are very safe and have nothing to do with reproductive function. Even one of the companies is organizing a study of its vaccine specifically for pregnant women.

Myth 5: Vaccines cannot be given to the sick and the elderly:

KOVID-19 vaccines are especially suitable for people with chronic non-communicable diseases such as diabetes, hypertension, heart, kidney, cancer, autoimmune and other diseases, as well as people over 75 years of age. In these people, the virus significantly increases the risk of a serious and even fatal course, which makes the benefits of vaccination even greater.

Myth 6: After vaccination I do not need to follow the measures against the epidemic:

Measures are needed to protect others, not just us. My answer to the myth that we become infected after vaccination also contains the reason why we must be careful and wear a mask.

Myth 7: COVID-19 vaccines have not been reliably tested:

Each of the vaccines registered for use by the US and the European Medicines Agency meets all the stringent licensing requirements. Registered vaccines have had clinical trials with tens of thousands of participants, and the actual application is now in the millions, and safety and efficacy data continue to be monitored through the so-called. pharmacovigilance system.

Myth 8: The vaccine will change my DNA:

Vaccines do not interact with the nucleus of our cells, where our DNA is stored. Our body is very careful and has many mechanisms that make it impossible. The direction of transcription is DNA-> RNA and only some complete viruses have a medium (specific enzyme) that allows the change of direction from RNA to DNA.

Myth 9: When I get the vaccine I can fly:

If there are brands in Chiprovtsi, it is not impossible. But why?

Myth 10: It is contraindicated / I do not need to be vaccinated because I had COVID-19 and I have antibodies:

Physical illness protects. Due to the wide range of proteins in the real virus, the response of our immune system is focused on many, and individually this virus also has proteins that suppress the immune response. Antibodies in recovered plasma are generally lower than those of the vaccine. There are no contraindications to vaccination, but the question is when.

How EU-approved vaccines work *

“Pfizer” – a matrix RNA vaccine, which through a nano-lipid shell injects into the muscles of the arm a quantity of genetic information that causes the formation of a viral protein (S-protein), with which the body begins to work with B- cells that form antibodies.

“Modern” – identical to “Pfizer”, but with a slightly damaged lipid shell, so it can be stored at higher temperatures.

AstraZeneca is a carrier vaccine. Here, unlike RNA vaccines, a virus (adenovirus) is used, which does not reproduce. It enters our cells, the cytosolic DNA is released, which is transcribed into RNA, and from there everything else looks like RNA vaccines.

How antigen vaccines work

Antigen vaccines use a protein that is introduced directly into the body to stimulate an immune response. The advantage is that this process starts immediately after the introduction of the antigen (there are no procedures that need to happen before). The disadvantage is the fact that systems that may contain traces of other allergens are used to produce antigens, as well as the fact that in order to work more successfully, it is often necessary to add the so-called. adjuvants, or immune-boosting substances.
