America tried to successfully vaccinate against Zika virus in animals

US scientists on June 28 announced that they have successfully tested the Zika virus vaccine in laboratory animals, opening hope for early production of human vaccines to prevent the virus from spreading. this fast.

Director of Harvard Medical School's Center for Vaccine and Vaccine Research, Dan Barouch, said two vaccine samples tested on laboratory mice helped "completely block" the Zika virus.

According to him, this positive result shows that it is possible to successfully develop a safe and effective vaccine against human Zika virus.

Dan Barouch is the co-author of the Zika anti-virus vaccine test , published in the journal Nature. Notably, two samples of these vaccines were tested with a single dose.

A separate study conducted by American scientists published in Nature Communications gives similar optimistic results.

Vaccine testing also shows that people who have been infected with Zika virus are less likely to become infected again in the future.

Scientists at the University of Wisconsin-Madison experimented with a sample of vaccine on brown monkey infected with Zika virus. The results show that the vaccine helps "completely protect" this virus.

The study's co-author Dawn Dudley said the research results are important because it shows that vaccines can effectively block the Zika virus. Vaccine testing also shows that people who have been infected with Zika virus are less likely to become infected again in the future, including pregnancy.

The results of the study open up hope to soon produce successful vaccine against Zika virus in humans. However, scientists said it would take many more months to test these vaccines on humans.

According to the World Health Organization (WHO), there are more than 60 countries and territories recording Zika infections. In Brazil alone, since the outbreak of disease in April 2015, more than 1.5 million cases have been detected.

Zika virus is transmitted by Aedes aegypti mosquito , sex and blood transfusion, with the most common symptoms of infection are fever, conjunctivitis, headache, muscle and joint pain, rash.

This is a dangerous virus, especially for pregnant women because it has the ability to cause minor head defects in the fetus, as well as cause many disorders such as Guillain-Barre disorder in adults, but no vaccines yet. or special medicine.

According to the WHO, there are currently more than 60 companies and research institutes participating in the development of Zika anti-vaccine, including 18 vaccine models specifically for women of reproductive age.
