In 1965, two CoV viruses related to respiratory diseases were discovered in the family, transmitted by animals and manifested from common colds to more serious diseases, such as Severe Acute Respiratory Syndrome (SARS). From this discovery, scientists will be able to advance the development of reliable and effective vaccines, such as the most recent ones against covid-19.

The name “coronavirus” was chosen to designate A new genre of the virus group (or prefix “crown” denotes a similarity that the virus has with a crown). When observed under a microscope, barnacles resemble the infectious bronchitis virus. TO IO Foundation, which focuses on studies on global health and travellers, states: “it has been demonstrated that several animal viruses not previously classified, including the murine liver virus and the porcine transmissible gastroenterite virus, show the same characteristic morphology under electron microscopy.” .

This new virus needs the attention of scientists and studies and investigations will begin to be developed immediately. “The number and importance of coronaviruses in animals will increase rapidly, with the subsequent inclusion of viruses that cause diseases in moments, cameldongos, galinhas, perus, bezerros, cães, cats, coelhos and pigs. From this data, other family members of this virus have been detected,” he says. IO Foundation . Studied for decades, some members of the group:

• HCoV-229E. Discovered in 1966. It causes a respiratory illness similar to influenza in humans.
• HCoV-0C43. Discovered in 1967. It causes a respiratory illness similar to influenza in humans.
• SARS-CoV. Origin of the SARS epidemic. It was discovered in November 2002, in the province of Cantão, China.
• HCoV-NL63. Identified in the Netherlands, in 2003, in a child with bronchiolite.
• HCoV-HKU1. Discovered in 2005 in two patients in the Chinese city of Hong Kong.
• MERS-CoV. It causes respiratory syndrome in the Middle East, an infectious disease identified for the first time in 2012, in Saudi Arabia.

Vaccines of all types are being developed around the world against covid-19, prepared, in accordance with World Health Organization (WHO), with a common objective: “to teach the body's immune system to reconstitute and block the virus that causes covid-19.” To meet this goal, various types of medications are being manufactured, such as:

• Vaccines as inactivated or attenuated viruses: we use a previously inactivated or attenuated virus, so that do not cause any disease, but provoke an immune response;
• Protein-based vaccines: We use harmless protein fragments or protein structures that mimic the virus that causes covid-19 to generate an immune response;
• Viral vector vaccines: We use a genetically modified virus that cannot cause illnesses, but can produce coronavirus proteins to generate a safe immunological response.
• RNA and DNA vaccines: A pioneering approach that uses genetically modified ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) to generate a protein that alone triggers an immune response.

To understand the event in the time we remember the vaccine against covid-19 or SARS-CoV-2, it is necessary to know that it does not arise from lack of knowledge, but that it is the result of quase two centuries of investigations, from the discovery of the first cows, It is the sum of all the technological advances that have also been strengthened as a characteristic of our era: continuous access to global information. Not for the first time that humanity manages to develop a vaccine with success, we can be proud, as a species, of the precise knowledge that we achieved and that guarantees that we can face the most recent problems.

With Insurance SURA, we can stay informed about the vaccination against covid-19, through specialists and professionals trained and willing to guide us at all times so that we can protect ourselves and prevent the advance of the pandemic, together. When we are all safe, we make sure to take care of our own health.
