COVID-19: Johnson & Johnson vaccine can still be used


The latest on COVID-19

Johnson & Johnson

Authorities from the Vaccine Committee of the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) gave the green light for the Johnson & Johnson vaccine to continue to be used in the United States.

The vaccine had been on hiatus after six cases of severe blood clots (one fatal) in six women.

The vaccine will be used with a special warning about these rare cases.

It is the only single dose vaccine available so far.

Covid in children

Public health authorities in the United States are recording a significant increase in covid cases in children. In Michigan alone, where the pandemic has hit hard, there were 70 cases of children hospitalized for covid in the week ending April 23.

A report from the American Academy of Pediatrics shows that children accounted for 1 in 5 cases detected nationwide during the second week of April.

Experts wonder if minors are more susceptible to the strain that emerged in the United Kingdom, and is circulating widely in the United States.

Other countries with emerging strains appear to be experiencing the same phenomenon. In Brazil, where a mutation of the coronavirus that causes covid-19 circulates, 1,300 deaths of babies and young children have already been registered.

The virus appears to cause a multisystem inflammatory syndrome, an exaggerated response of the immune system to the presence of the coronavirus, which can be fatal.

Covid home test

In Germany, Switzerland, the Netherlands, Austria, and now in South Korea on a conditional basis, home tests for covid are already being used. The sensitivity rates of the tests developed by SD Biosensor and Humasis are 90% and 89.4% respectively.

United States already vaccinated 16 years and older

Adolescents 16 years and older are already receiving the Pfizer vaccine, the only one licensed so far for that age group.

In Montgomery County, Maryland, under the slogan “No arm Left Behind,” Governor Larry Hogan launched a campaign to get the entire adult population vaccinated soon.

Pfizer vaccine

Albert Bourla, CEO of pharmaceutical company Pfizer, said a third dose of the vaccine is likely to be needed six to 12 months after the second to boost 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 (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 one 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 the 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 your arm, not your hand). Masks should be used, especially indoors.

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