needle end?  AstraZeneca is testing a nasal Covid-19 vaccine

Good news for those who are afraid of injections (almost everyone, right?): British laboratory AstraZeneca has successfully tested an aerosol version of the Covid-19 vaccine. The survey is conducted in the United Kingdom and the United States.

But calm down! There is still a long way to escape from the sting. At the moment, tests have only been done on animals, such as hamsters and monkeys. But the researchers did find that applying the nasal vaccine helped reduce the viral load in the control group, causing the virus to spread less.

Recent studies have shown that transmission of the virus is possible even from people who have already been vaccinated, which reinforces the importance of wearing masks and maintaining social distance. Nasal application is an additional option to prevent further spread of the virus.

In another recent research, scientists at the University of Alabama, USA, concluded that intranasal application of vaccines makes more sense to fight the disease, because the path of COVID-19 infection runs through the nose, throat and lungs. But the use of an immune spray should ensure protection only for a shorter time than when applied intramuscularly.

Researchers suggest that the best option to protect yourself from the virus is to combine application to the arm and application to the nose, to ensure a greater range of protection.

Earlier this year, Jorge Kalil Filho, director of the Immunology Laboratory at Instituto do Coração at Hospital das Clínicas, Faculty of Medicine, revealed that he had conducted advanced studies to produce a 100% national version of the immunizing agent against Covid-19. But no date has been set for the start of testing yet.
