Latest on COVID – 19
Pfizer
The pharmaceutical company Pfizer applied to the United States Food and Drug Administration (FDA) for authorization full of your covid vaccine – 19 for people of years and older.
The vaccine obtained an emergency use authorization from FDA on 12 December 2020. It is a designation that is granted when a drug or vaccine is showing encouraging results in large clinical trials, to avoid bureaucracy that can take years until authorization.
The others Two that are approved for emergency use in the United States are Moderna and Johnson & Johnson vaccines.
Pfizer partnered with the German company BioNTech to produce a vaccine against covid, which was obtained in record time: less than a year.
It is the first pharmaceutical company to request full authorization, which enables it to market the vaccine directly and generate new forms of the vaccine against new strains of coronavirus without having to request an emergency authorization again.
It is expected that this use of a cot will be approved soon for adolescents between Y 15 years.
Pfizer has already delivered 170 million doses in the United States.
Vaccines for all
The Biden administration announced that it will support a controversial measure to exempt covid vaccines from intellectual property rights.
Giving up these rights would make it easier for some countries to export these vaccines, and for others to receive them.
The government de Biden clarified that he firmly believes in the intellectual property of a product, but that, in this case, at least temporarily breaking down the bureaucratic barriers that limit production and export would help to dramatically increase immunization, with the goal of ending the pandemic.
The proposal for this exemption had been presented last fall by India and South Africa before the World Trade Organization.
“As our supply of vaccines to the American people is secured, the Administration will continue to intensify its efforts, working with the private sector and all possible partners, to expand vaccine manufacturing and distribution. It will also work to increase the raw materials needed to produce these vaccines, “said Casa Banca in a statement.
More doses for adolescents
The United States Food and Drug Administration (FDA) may be authorizing the covid vaccine – 19 by Pfizer Youth to 15 years the second week of May, setting a massive new round of vaccinations for many before the start of the next school year.
The process that must be approved by the Centers for Disease Control and Prevention. CDC) will be faster because it would be an emergency authorization, as in the case of the adult version.
Masks
The United States Centers for Disease Control and Prevention (CDC) said that people completely immunized (that is, two weeks after the second dose of the covid vaccine) can be outdoors without a mask if they go for a run, walk or ride a bike, or if they plan to have dinner with friends in restaurants with tables outside.
The highlights of the changes to the CDC recommendations would be:
- Fully vaccinated people no longer need to wear a mask outdoors, except in certain crowded places.
- They emphasize that immunosuppressed people should consult their healthcare provider about these recommendations, even if they are fully vaccinated.
- They clarify that fully vaccinated workers should no longer be restricted from work after exposure, as long as they are asymptomatic.
- Fully vaccinated residents of congregated unsanitary settings (such as hog older adults) no longer need to be quarantined after a known exposure.
- Fully vaccinated asymptomatic people without exposure may be exempted from routine screening tests, if possible.
AND l Fully vaccinated people can:
- Visit other fully vaccinated people indoors without wearing masks or physical distancing
- Visiting unvaccinated people (including children) from a single household who are at low risk of severe covid disease –
- Participate in outdoor and recreational activities without a mask, except in certain crowded places
- Resume domestic trips, no need for tests before or post-trip or post-trip self-quarantine.
- Refrain from testing before leaving the United States for international travel (unless the destination requires it) and refrain from self-quarantine after returning to the United States.
- Refrain from performing testing after known exposure, if asymptomatic, with some exceptions for specific environments
- Refrain from quarantine after exposure known if asymptomatic
- Refrain from routine screening if asymptomatic and feasible
For now, fully vaccinated people should continue:
- Take precautions in indoor public settings, such as wearing a well-fitting mask
- Wear well-fitting masks when visiting the interior ior with unvaccinated people at higher risk of contracting a severe form of covid – 19 or who have a limb unvaccinated household that is at increased risk of developing severe COVID.
- Wear well-fitting masks when visiting indoors with uninvolved vaccinated from multiple households
- Avoid large in-person meetings indoors
- Get tested if you experience covid symptoms – 19
- Follow the guidance issued by individual employers
- Follow CDC and health department travel requirements and recommendations
Pfizer vaccine
Albert Bourla, CEO of the pharmaceutical company Pfizer , said a third dose of the vaccine is likely to be needed in six to after the second, to reinforce ar immunity.
This strengthens the idea that the covid vaccine could be seasonal, requiring an annual dose, as is the case with the flu vaccine.
Scientists still don’t know how long immunity lasts after the two doses.

What are coronaviruses
Coronaviruses (CoV) are a broad family of viruses that can cause various conditions, from the common cold to more serious diseases, such as the coronavirus causing Middle East respiratory syndrome (MERS-CoV) and causing severe acute respiratory syndrome (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 usually 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 cover your mouth and nose when coughing and sneezing (with the arm, not the hand). Masks should be used, especially indoors.
Close contact with anyone with signs of respiratory disease, such as coughing or sneezing, should also be avoided. Comply with 6-foot (two-meter) social distancing and stay home if symptoms appear.
