Zika virus: No vaccine for women before 2020, says WHO
The World Health Organization (WHO) on Wednesday said that about 40 potential vaccines for the Zika virus are being tested, but none are likely to be available for women of childbearing age before 2020.
New Delhi: Researchers have been working hard to find cures for several lethal diseases that medical science is not able to make a breakthrough at the moment.
While many of their researches have yielded promising results, helping people achieve better quality of life, the quest to find cures remain a paramount task for scientists worldwide.
Similarly, a number of research has been carried out on Zika to better understand the virus' natural history and evolution, viral biology, transmission and pathogenesis as well as the creation of vaccines and drugs.
However, the World Health Organization (WHO) on Wednesday said that about 40 potential vaccines for the Zika virus are being tested, but none are likely to be available for women of childbearing age before 2020.
WHO director Margaret Chan said the virus, linked to deformations in babies' heads and brains, remained "firmly entrenched" in large parts of the world.
Although progress toward effective prevention has been made, with some drugs now in clinical trials, "a vaccine judged safe enough for use in women of childbearing age may not be fully licensed before 2020," Chan said.
The agency declared in November that Zika was no longer a public health emergency, though Chan said today that the WHO was setting up a new support programme for countries around the world.
The outbreak, which emerged in Brazil in 2015, has affected some 70 countries.
While Zika, spread by infected mosquitoes as well as by sexual contact, causes only mild symptoms in most people, pregnant women with the virus risk giving birth to babies with microcephaly, a crippling deformation that leads to abnormally small brains and heads.
In June, the WHO said USD 122 million (113 million euros) was needed to fund an 18-month plan to fight infections of women of childbearing age.
Till date, there's no vaccine or specific treatment for Zika. Instead, treatment focuses on relieving symptoms, which include rest, rehydration and acetaminophen for fever and pain. Patients are advised to avoid aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.
