Zika Vaccines; No Vaccine or Prophylactic Treatment Is Available For the Prevention of Zika Virus

Zika vaccines have been developed for vaccination and prevention against diseases caused by the zika virus, which belongs to the genus Flavivirus and is transmitted by Aedes mosquitoes. It can be also transmitted through blood transfusion, sexual contact, or infected pregnant women to the fetus. In 2016, the World Health Organization announced that the zika virus no longer constitutes a public health emergency of international concern because the major causes of the virus were asymptomatic. As of January 2020, there are no areas with a current Zika outbreak.

However, Zika is still a problem in many parts of the world. Thus, travelers should take steps to prevent getting the virus during travel, as well as to prevent spreading it when they return home, as there is no medicine or vaccine for Zika. The Zika virus has been spreading to parts of the world ever since it was discovered. Until now, several clinical trials have been conducted on Zika vaccines to prevent the disease. As of April 2019, no Zika vaccines have been approved for clinical use, although there are currently several vaccines in clinical trials. 

The goal of the Zika vaccines is to produce specific antibodies against the Zika virus to prevent infection and critical illness. Currently, no vaccine or prophylactic treatment is available for the prevention of the virus, but there are medications and treatments available to help reduce the discomfort associated with the disease. However, there are different types of vaccines that may protect against the Zika virus, such as genetically engineered vaccines, mRNA vaccines, purified inactivated vaccines, live attenuated vaccines, viral vector-based vaccines, and DNA-based vaccines. 

Zika outbreaks have been reported in the Pacific region, South/Central America, the Caribbean, Africa, and parts of south and Southeast Asia. According to the Centers for Disease Control and Prevention (CDC), in 2018 and 2019, there have been no reports of Zika virus transmission by mosquitoes in the continental United States.
