The coronavirus vaccine. All you have to know.


There are coronavirus vaccine? When will it be available? There are many doubts that the coronavirus is generating in society and one of them revolves around a vaccine that prevents the spread of these diseases. At first I have to say that there is no vaccine that can prevent coronavirus disease, but there is good news, because it is being worked on and apparently it only takes a few months to be able to use it.

The coronavirus was discovered in the 1960s and is named for its corona-like appearance when viewed under a microscope. It is known as a zoonotic virus, since it is transmitted from animals to humans, being more than all its reservoir the bat.

Its symptoms may appear as a mild picture, similar to a common cold in 80% (rhinorrhea, fever, sneezing) of cases or a moderate picture due to the presence of pneumonia in 15% of situations (frequent dry cough, dyspnea), which could evolve to a serious condition in 5% of the population with respiratory distress and failure and subsequent death of the patient if it is not treated in time and adequately. As for its best known strains we have:

- SARS (Severe Acute Respiratory Syndrome) which was discovered in China in 2002.

- The MERS (Middle East respiratory syndrome) discovered in the Middle East in the year 2012.

- AND the 2019-nCov discovered last December in Wuhan China, being the most serious so far since in a short time it has evolved into an epidemic and possible pandemic, caused by the fact that transmission can also occur from person to person through the respiratory tract.

Its treatment is symptomatic and depends on the condition of each patient.

As I have already informed you in previous posts, there is no vaccine that prevents coronavirus infection, But the good news is that countries such as the United States, China and Australia are currently developing a vaccine that is only to be carried out in human clinical trials and to begin testing its effectiveness in a few months.

The idea of ‚Äč‚Äčthese researchers and pharmaceutical companies is to stop the epidemic of this strain of coronavirus as quickly as possible, which already has more than 80,000 infected and 2,700 deceased.

The first vaccine was made in Australia, where scientists at the University of Queensland, in January this year, without having the virus, worked on its genome (disseminated on the Internet by Chinese scientists). For this, a type of molecular technology was used, called 'molecular trap technology', invented by themselves, where they identified and modified a section, known as spicular protein, in order that the patient's immune system can identify and neutralize the coronavirus.

The vaccine will be tested first in animals and then in humans. If the results are positive, the most susceptible population will begin to be immunized first and then the rest of humanity.

Meanwhile, in Massachusetts, the United States, a small biotechnology firm, called Moderna, sent a first batch of vaccines to the National Institute of Allergy and Infectious Diseases, where clinical trials in a group of healthy volunteers will begin at the end of April, to verify that the vaccine is safe and effective.

If the immune response of the organism of these volunteers is as expected, the vaccine could be available for July or August of this same year.

And in China itself, at Tianjin University, they allegedly created 'successfully' an oral vaccine based on brewer's yeast (saccharomyces cerevisiae), which is a single-celled fungus that attacks the spiculate protein of the virus and as a consequence, produces antibodies.

It is imperative to create a vaccine against the coronavirus, urgently, especially against this strain (2019-nCov), which has become a global epidemic with possible extension to a pandemic.

And, I will not tire of repeating it, one of the best ways to prevent coronavirus contagion is through the adoption of the following measures:

1. Wash your hands frequently, with soap and water for more than 20 seconds. The WHO (World Health Organization) gives us recommendations on how we should properly disinfect our hands.

2. Clean the objects you use frequently, such as cell phone, tablet, laptop, keys ...

3. Use a mask or face mask in areas where the presence of the virus is proven.

4. Don't touch your face and eyes.

5. If you have a coughMake it on bouncy paper or in the crook of the elbow.

6. Avoid contact with people suspected of coronavirus and / or crowds.

7. Using antibacterial on hands.

8. If you have any suspicious symptoms and, above all, if you have had contact with an infected person or have been in a risk area, go to the doctor or take your child to the pediatrician.

9. Do not self-medicate.
