In 1965, the CoV family of viruses was discovered, which are related to respiratory diseases, transmitted by animals and manifested from common colds to more serious diseases such as Severe Acute Respiratory Syndrome (SARS). Since its discovery, scientists have made progress in developing reliable and effective vaccines such as the most recent ones against COVID-19.

The name coronavirus was chosen to designate a new genus of this group of viruses (the prefix corona denotes the crown-like appearance of the projections on the surface). When viewed under a microscope, it was found to resemble infectious bronchitis virus of chickens. IO Foundation Global Health and Travel, states: “A number of previously unclassified animal viruses, including murine hepatitis virus and porcine transmissible gastroenteritis virus, were shown to exhibit the same characteristic morphology under electron microscopy.”

This new virus caught the attention of scientists and studies and research were not long in coming. “The quantity and importance of Coronaviruses in animals grew "The virus was rapidly detected, with the subsequent inclusion of viruses that cause diseases in rats, mice, chickens, turkeys, calves, dogs, cats, rabbits and pigs. Since then, other members of the family of this virus have been detected," he says. IO FoundationThe members of this family, which have been studied for decades, are:

• HCoV-229E. Discovered in 1966. Causes a flu-like respiratory illness in humans.
• HCoV-0C43. Discovered in 1967. It also causes a flu-like respiratory illness in humans.
• SARS-CoV. It caused the epidemic of severe acute respiratory syndrome. It was discovered in November 2002, in the province of Guangdong, China.
• HCoV-NL63. Identified in the Netherlands in 2003, in a child with bronchiolitis.
• HCoV-HKU1Discovered in 2005 in two patients from the Chinese city of Hong Kong.
• MERS-CoV. It causes Middle East respiratory syndrome, an infectious disease that was first identified in 2012 in Saudi Arabia.

All over the world Vaccines of all kinds are being developed against COVID-19, designed, according to the World Health Organization (WHO), with a common goal: “to teach the body's immune system to safely recognize and block the virus that causes COVID-19.” Different types of drugs are being manufactured for this purpose, namely:

• Vaccines with inactivated or attenuated viruses: They use a previously inactivated or attenuated virus, so that does not cause disease, but still generates an immune response.
• Protein-based vaccines: They use harmless protein fragments or protein structures that mimic the virus that causes COVID-19, in order to generate an immune response.
• Viral vector vaccines: They use a genetically modified virus that cannot cause the disease, but can produce coronavirus proteins to generate a safe immune response.
• RNA and DNA vaccines: a pioneering approach that uses ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) genetically modified to generate a protein that by itself triggers an immune response.

To understand the record-breaking success of the COVID-19 or SARS-CoV-2 vaccine, we must know that it does not arise from ignorance, but rather is the result of almost Two centuries of research since the discovery of the first vaccines and it is the sum of all the technological progress that has also been strengthened by the characteristic of our era: continuous access to global information. This is not the first time that humanity has achieved success with a vaccine; in fact, we can feel proud, as a species, of the refined knowledge that we have achieved and that ensures that we can face recent problems.

With insurance SURA We can stay informed about COVID-19 vaccinations through trained specialists and professionals who are ready to guide us at all times to protect ourselves and counteract, together, the spread of the pandemic. Ensuring that we are all safe will be the greatest guarantee of our own health.
