COVID-19: Pfizer requests authorization to use its vaccine


The latest on COVID-19

Vaccinations

The Pfizer laboratory requested on Friday, November 20, the emergency authorization for its vaccine against COVID-19 to the Food and Drug Administration (FDA) of the United States.

The pharmacist had reported that in preliminary results from phase 3 of the clinical trial, the vaccine had shown a 95% efficacy in preventing infection.

The safety measures that the vaccine has shown and its percentage of efficacy make it a candidate for this emergency use, which occurs when a drug or vaccine proves to be effective.

The laboratory is also applying for similar authorizations in the European Community and the United Kingdom.

Mexico

Mexico exceeded one million COVID-19 diagnoses and the week of November 16 is approaching 100,000 deaths from this infection, according to the Johns Hopkins University case monitoring.

It is the fourth country worldwide in number of deaths after the United States, India and Brazil.

Critics of how Mexico has coped with the pandemic say insufficient testing is being done, making contact tracing almost impossible.

President Andrés Manuel López Obrador downplayed the severity of the pandemic from its inception, saying that “life must go on” because the poorest cannot be kept in quarantine.

In Latin America

The International Labor Organization, a United Nations body, said that because of the pandemic, the region has lost 34 million jobs. This consequence of the public health crisis has deepened the already endemic economic crisis in the region, and increased the poverty gap.

Latin America lost 20% of working hours, compared to 11% in the rest of the world.

study

New research reveals that nearly 1 in 5 people diagnosed with COVID-19 are diagnosed with a psychiatric disorder such as anxiety, depression or insomnia within three months of infection.

The study was conducted by researchers at the University of Oxford, using electronic medical records for millions of patients treated in the United States.

The researchers noted that unlike people diagnosed with other medical conditions from flu to kidney problems, patients diagnosed with COVID developed these mental health disorders within 90 days of becoming known to be infected.

It also happens that people with psychiatric disorders have a 65% higher risk of being diagnosed with COVID.

Scientists begin to investigate the reasons behind these findings.

Europe

The continent begins to require new quarantines after COVID cases reached record numbers in recent weeks.

The region reached 5 million cases in nine months, but the next 5 million occurred in just one month.

With 10% of the world’s population, Europe accounts for approximately 22% of the global burden of 46.3 million infections.

With more than 269,000 deaths, the region represents about 23% of the global death toll from COVID-19: almost 1.2 million lives, according to Reuters.

What are coronaviruses

Coronaviruses (CoVs) are a broad family of viruses that can cause a variety of conditions, from the common cold to more serious illnesses, such as the Middle East respiratory syndrome coronavirus (MERS-CoV) and the coronavirus that causes respiratory syndrome. severe acute (SARS-CoV). A new coronavirus is a new strain of coronavirus that has not been found before in humans.

How do you get coronavirus?

Coronaviruses can be transmitted from animals to people (called zoonotic transmission). Studies have shown that SARS-CoV was transmitted from the civet to humans and that transmission of MERS-CoV from dromedary to humans has occurred. In addition, it is known that there are other coronaviruses circulating among animals, which have not yet infected humans.

Characteristic symptoms

These infections often cause fever and respiratory symptoms (cough and dyspnea or shortness of breath). In the most severe cases, they can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

Also headache and loss of taste and smell.

How to prevent contagion

The usual recommendations to avoid spreading the infection are to wash your hands frequently and to cover your mouth and nose when coughing and sneezing (with your arm, not your hand). Masks should be used, especially indoors.

Close contact with anyone with signs of a respiratory condition, such as coughing or sneezing, should also be avoided. Comply with the 6 foot (two meter) social distancing and stay home if symptoms appear.
