Janssen's vaccine will prove its effectiveness in newborns and pregnant women

46

The vaccines that are currently being administered have not been tested in young children, nor in pregnant women, whose vaccination must be evaluated individually. None of them are recommended for children under 16 years of age in the case of Pfizer, or 18 years of age in the case of Moderna, AstraZeneca and Janssen. Trials are currently underway in younger children, for example AstraZeneca is testing children between the ages of 6 and 17, while Pfizer is also testing pregnant women.

Below that age, Johnson & Johnson has announced that it is preparing trials to test its single-dose coronavirus vaccine in children and even newborns, as well as in pregnant women and in people with compromised immune systems.

A spokesperson for Janssen Biotech , the Johnson & Johnson subsidiary that makes the vaccine, confirmed to The New York Times that the company plans to extend clinical trials to children.

The Pfizer and Moderna vaccines, which are being administered to adults, are also planned to be gradually tested in increasingly younger age groups. They are currently being tested in children over the age of 12.

Johnson & Johnson will first test its vaccine in children between the ages of 12 and 18, but plans to begin a study that includes newborns immediately afterward.

The company will then test its vaccine in pregnant women and, finally, in immunosuppressed people. You will then be able to assess safety and immune responses in these groups.

The Janssen vaccine, unlike vaccines that use messenger RNA technology, is manufactured using a method that has been extensively tested for years. An inactivated adenovirus , similar to the viruses that cause the common cold, is introduced and instructs cells to make copies of the virus’s spike protein. The immune system then produces antibodies that can block a Covid infection before it starts.

Among these types of vaccines there is one for Ebola, which has been safely administered to babies as young as one year old, and another for the respiratory syncytial virus that has been safely administered to newborns , says the US media.
