The week of hope: 3 vaccines show that covid-19 may end

After nearly eight months of research, science has made a major leap in the last week. Three vaccines had positive results reported on the efficacy in combating the new coronavirus. They came from the United Kingdom, China and the United States.
Vaccine projects were safe in humans and also generated an immunological response against the new coronavirus. The feat was achieved by Oxford University, in partnership with astrazeneca pharmaceutical company, the Beijing Biotechnology Institute and american drugmaker Pfizer in partnership with german biotechnology company BioNTech.
The advances are significant, but experts continue to recommend measures of social distancing and use of masks because the pandemic of the new coronavirus is not over yet. One more important stage of testing remains to be overcome: to verify that any of the vaccines generates enough immunity to protect the human body from infection of the new coronavirus.
The week has brought good news and hope to billions of people around the world, and the advances deserve to be celebrated. But you have to be careful because the virus is still circulating. While the whole world has 14.5 million cases, Brazil alone records more than 2 million and more than 1,000 people die daily as a result of covid-19.
Combating coronavirus requires agility and science has exceeded its limits. Creating a vaccine can take up to 10.7 years, according to research by researchers in the Netherlands. If the coronavirus vaccine is ready later this year, it will be the fastest vaccine ever created by mankind, surpassing the Ebola virus vaccine, which took five years to develop.
Next Monday begins with another hope: the vaccine of the Modern American pharmaceutical enters the stage 3 of testing, as well as the most advanced vaccines of the moment. It is impossible to predict which company will be victorious in the vaccine race. But the world hopes that some of them will succeed and then begin the end of the pandemic that marked the year 2020.
