How Effective will the Corona Vaccine Work In The Event of a Virus Mutation? 


Currently the corona vaccine is still in the development stage. There are many questions that arise regarding the corona virus vaccine. One of the big questions is how effective will the corona vaccine work in the event of a viral mutation?

All viruses evolve over time including the corona virus. So far there is no evidence that the mutated corona virus is more deadly than others. Of the 1,000 different corona virus samples, Peter Thielen, a molecular geneticist at Johns Hopkins University's Applied Physics Laboratory said there are only about four to 10 genetic differences between viruses that infect people in the United States and native viruses that spread in Wuhan.

This number is relatively small because it has passed through a large number of people. Based on this fact it is believed that the virus vaccine to be developed will be a single vaccine whose immunity will last for a long time. 

Virus Mutations Weaken The Virus

As the coronavirus spreads around the world, there are fears that the virus will mutate into something more deadly and become a more frightening threat. In fact, viral mutations don't always mean bad. 

As mentioned earlier, each virus mutates and it is part of the life cycle of the virus. Such shifts and changes are not always a big deal. In fact, in some cases, the mutation can cause the virus to weaken. However, it usually changes because mutations are very small, so there is no noticeable difference in the rate of transmission and death.

According to Dr. Benjamin Neuman, head of the Department of Biology at Texas A&M University-Texarkana said that almost all mutations will make some parts of the virus work less well than before. The most common thing to happen is when a mutation occurs, the virus weakens then dies. Certainly, the characteristics and nature of the virus are not much different between mutated and the original.

So, how effectively does the corona vaccine work against this viral mutation? Precisely the slow nature of mutations is good news for vaccines. Moreover, the absence of significant changes between mutated viruses and native viruses makes the vaccine work in accordance with its function without any significant obstacles. 

Corona Virus Vaccine Effective Against Covid 19

Vaccines, in general, tend to target early versions of the virus. For example the flu vaccine, in which the flu vaccine still uses a genetic version of the virus in 2009. Typically, older types of viruses will retain features that will provide immunity to the entire group of virus variants including when it has mutated. 

However, the flu virus mutates quickly and erratically from year to year. In addition, our immune system has poor memory for flu viruses. That is why, flu vaccines are recommended to be administered periodically once a year.

Well, this coronavirus is something different. Through observation of corona virus characterization, it is concluded that corona virus mutations do not undergo significant changes from the initial genetic.

That means the vaccine currently being developed is believed to provide long-term immunity to the virus. There could be random mutations but infections caused by these random mutations will not be life-threatening. 

Staying positive and following health protocols is an effort that can be made today. If you want to know more about coronavirus vaccine or other health information find out directly in Hospital. 

Prevent Corona by Washing Hands, Should You Use Special Soap?

Prevent Corona by Washing Hands, Should You Use Special Soap?

Since the beginning of its appearance at the end of 2019 in Wuhan, China, now the corona virus or COVID-19 has infected nearly 200 thousand citizens of the world. Since the beginning, WHO has recommended prevention efforts, one of which is to regularly wash hands with soap and running water.

Although the use of hand sanitizers is also recommended, experts agree that washing hands with soap and running water is a must. Some media are busy re-popularizing the correct hand washing technique. The question is, do you have to use special soap, such as soap that is antibacterial? Or are all soaps equally effective.

Is It Necessary to Use Special Soap?

All types of viruses including COVID-19 can be active outside the human body for hours, even days. They can spread through droplets, such as when sneezing, coughing, or when the sufferer speaks. Disinfectants, hand sanitizer fluids, wet wipes, gels, and creams containing alcohol are all useful for killing this virus, but not as effective as soap.

When doing daily activities, it can be difficult for hands to avoid viruses, bacteria, or germs. The cause is that the eye is unable to see the virus directly, so hand washing is the best step to avoid contracting the disease. According to the Huffington Post, family physician Dr. Neha Vyas at the Cleveland Clinic said you should wash your hands for at least 20 seconds.

In addition, he also added that this type of soap is not important. This is because COVID-19 is a virus, so antibacterial hand soap does not give an additional advantage over other types of soap. 

Dr. Carl Fichtenbaum, an infectious disease expert at the University of Cincinnati College of Medicine also said that so far there is no clear evidence that antibacterial soaps work better than other soaps. He said that the most important thing is to wash your hands for at least 20 seconds with the correct technique. 

Why Is Soap Considered The Most Effective?

World Economic Forum professor Palli Thordarson at the School of Chemistry at the University of New South Wales, Australia also took to Twitter to explain some of the molecular chemistry-related things that help explain why soap is more effective at killing viruses. 

Thordarson explained that viruses tend to consist of three things: the nucleic acid genome (genetic material: DNA or RNA), a protein that wraps around nucleic acids and helps replicate viruses in the host's body, and a fatty outer layer. The connection between these three parts of the component forms the structure of the virus, but the connection is weak because there is no covalent bond that provides a more stable structure.

Instead, says Thordarson, viral assembly is based on weak "non-covalent" interactions between proteins, RNA and lipids. They together act together like adhesives making it difficult to break down self-formed viral particles.

However, it is possible to break down particles with soap, which is good at dissolving the lipid layers that surround the virus. It also destroys all other weak bonds in the virus. Once that happens, the virus will effectively fall apart.

Washing with water alone is much less likely to remove the virus from the surface of the skin. So, wash your hands with soap because it contains fat-like compounds called amphiphiles, which are similar to lipids found in viral membranes. When soap comes into contact with this fatty substance, it binds to it and causes it to detach from the virus. It also forces the virus to detach from the skin.

When Soap and Water Are Not Available

Of course, not in all places there is clean water, soap, and sink. Therefore, hand sanitizer can also be an alternative. Always carry a small bottle of hand sanitizer and use it after coming into contact with people and surface objects such as handles on buses or trains, door knobs, or other objects that are prone to being touched by many people. 

Use a hand sanitizer with an alcohol content of at least 60 percent or more. Alcohol-free hand sanitizer products are currently also sold in various places, but they are not recommended by the Centers for Disease Control and Prevention.

The CDC recommends soap and water because the process is better at killing certain types of germs, including the COVID-19 virus. Especially if your hands are dirty or greasy, the hand sanitizer will also not clean them effectively.

So, be sure to clean your hands with soap as often as possible. If you feel symptoms similar to coronavirus infection, do not delay again to check it out to the hospital.
