Covid 19 has created a situation that has surprised and confused many immunologists, doctors, nurses and even politicians. We have been dealing with this huge pandemic for a long time and we are bearing its consequences. These days, one of the most important concerns of every human being is to be vaccinated against the corona virus. This issue has created a useful competition between vaccine production companies to make the best and most effective vaccine. The newest vaccine that has been introduced to the world is labeled vaccine.

If you need more information about the types of corona vaccine and its new type, the labeled corona vaccine, I suggest you consult an infectious disease specialist. In your doctor, you can find the best infectious disease specialist to diagnose and treat corona virus and consult about different types of corona vaccine.

new labeled corona vaccine

Currently, the most effective way to prevent contracting COVID-19 is the coronavirus vaccine. Perhaps, upon hearing the name of vaccine, the only image that forms in our mind is a vial of medicine that is injected into the body through a small syringe. This image is the closest and most tangible idea of ​​the vaccine. It is probably impossible for you to imagine a labeled vaccine. Even the idea of ​​an oral polio vaccine is not very tangible. It is better to know that the only form of vaccine is not injection, but there are different types. The question that arises is what is the best form of vaccine?

In order for a vaccine to be most effective, the type of drug, the time and the way it enters the body are decisive in immunogenicity. Corona immunization is done with various vaccines, some of which are; Sinopharm, Pfizer, Moderna, Sputnik and Astrazeneca. Regardless of the type of medicine in the vaccine vial, the way it enters the body is also an effective factor in increasing its effectiveness. In this article, we will examine a new type of label vaccine that was recently introduced.

effectiveness of new labeled corona vaccine

Standford and North Carolina universities have recently introduced a vaccine in the form of a label instead of an injection in their new research. This 3D vaccine creates a much more effective immunity than its injectable type. Stanford University researchers announced that the newly designed vaccine is both less painful and miraculously more effective than other types of vaccines.

This vaccine label is very small. According to the information that its manufacturers have published in the articles, their labeled vaccine contains 100 microneedles or very small needles measuring 1 square centimeter. These three-dimensional microneedles are 700 micrometers long. These needles are long enough to enter the skin and leave their effect on the body.

This vaccine has been experimentally tested on mice and the results have been surprising. The effectiveness of this vaccine after entering the body after 3 weeks has been 20 times stronger than the normal injection of the vaccine in the deltoid muscle of the hand. Also, the antibody produced in the body after one month was 50 times more than the traditional form of vaccine injection. This amount of difference is very impressive!

Vaccines that are injected in the traditional way enter the muscle or under the skin. But this type of vaccine enters the skin with its very short needles and does not reach its underlying layers. But which one works better? It is better to know that there are many immune cells in our skin. These cells react upon receiving the vaccine and protect the body in a shorter time. Therefore, intradermal injection is the best type of vaccine injection. It is painful to do this injection with regular needles. It also causes more complications. The introduced vaccine microneedles do not have these defects and are extremely effective.

What are the benefits of labeled vaccine?

If you are looking for injectable vaccine is better or label vaccine continue this article and know the benefits of label vaccine:

1. It doesn't hurt

As mentioned, the needle is at least 2.5 to 3 cm or more in length. Entering this size needle into the body causes pain and sometimes fear for the patient. There are not few people who are afraid of injection and the only reason for them is the pain of the needle inserted into the body. The tiny needles of the label vaccine are so small that they do not cause any pain to the person when they enter.

2. It can be injected alone

The injection of this vaccine does not require a specialist or an operator. Anyone can buy them and use them according to a 1 or 2 line instruction. When the force of vaccine injections is not needed, time and energy are significantly saved. Also, the vaccination operation is performed at a better speed.

One of the most important things that must be observed in vaccine transfer is maintaining the cold chain. Since vaccines are killed, weakened, or antigens of microbes, they must be kept at a certain temperature until they can be injected. If vaccines are placed in unfavorable conditions anywhere during the transfer process from the place of production to injection, there is a possibility of their spoiling and destruction. The very interesting thing about the label vaccine is that it does not need to be transported with a cold box (a cold box containing ice packs that transports the vaccine).

So far, nearly 2 billion people in the world have been vaccinated against Corona and have become immune to it. But there are still people who live in remote areas and due to the lack of facilities, it is difficult and even impossible to transfer the vaccine to them. As mentioned, maintaining the cold chain is very important in the transfer of the vaccine. If the produced vaccines do not need to maintain this chain, their transfer will be very simple. The newly designed label vaccine could be a good choice for delivery to all parts of the world. Because this vaccine can remain healthy for 30 days at room temperature.

You can use your doctor's drug consultation service to get more information about the corona vaccine.

What is a cold chain?

The system that keeps the temperature of the vaccine constant from the moment of production to the moment of distribution is called cold chain. The equipment that helps maintain the temperature of the vaccine includes two fixed and mobile parts.

• Fixed parts include refrigerators, generators, cold storage and warning alarms.
• The mobile sector includes cold boxes, carrier vaccines, ice packs and refrigerated cars.

As you can see, in order for the vaccine to be usable and to maintain its temperature, a lot of equipment and money is required. Now imagine that the vaccine is transferred from one country to another. These costs and facilities must be multiplied. Large vehicles such as ships and airplanes should be used, and cold storage facilities should be different from those used in city-to-city transportation.

Making a vaccine that does not require all these costs is a wonderful and unique development. Labeled vaccines can save humanity. They will also advance the pace of vaccination and pandemic control at an unbelievable speed. In addition, the savings in time and money are so impressive that it is worth investing in microneedle technology.

4. It is more stable

FDA has approved three types of vaccines, one of which is based on protein and the other two are based on RNA. All 3 approved items must be transported at a certain temperature. In addition, they must be injected intramuscularly by a trained person. The vaccine designed by Stanford and Carolina University researchers is based on DNA. In addition, it does not require an injection person and maintenance in special conditions. A vaccine based on DNA is more stable than an RNA vaccine.

problems of mass production of labeled vaccine

According to the available information about this vaccine, its use is very effective and affordable. In short, if we want to enumerate the benefits of this vaccine, they are;

• Injecting it is very simple and does not require trained personnel.
• Its effectiveness is higher than other methods of receiving the vaccine.
• There is no need to spend money and have special equipment to transfer it.
• Its injection is painless!
• Its stability is higher than other vaccines.

But besides these good things, there are problems in the process of its mass production. Microneedles are not new inventions, but their manufacturing technology has hindered their mass production. If the difficulties of making them in large numbers are overcome, they can be used to inject measles, influenza and hepatitis vaccines. The most important concern of the makers of these small needles is to make them in the best way and with the lowest cost. According to the latest statistics given by the research team of these labeled vaccines, their next step is to make Moderna and Pfizer labeled vaccines.

Can label vaccines replace traditional vaccines? Can these vaccines be widely used in the world? These are questions that we will see the answer to over time.
