23 Vaccine projects against Zika virus are in development, says WHO
"Experts agree that the development of a vaccine against the Zika virus is imperative," he said. "Projects in progress may start clinical trials before the end of 2016, but it may take years before a fully tested and licensed vaccine is available," he added. These early studies are focused on vaccine availability for pregnant or reproductive age women due to the risk of microcephaly.
According to the WHO Director-General, more than 30 companies are currently working on the development of new diagnostic tests of Zika's infection. "With regard to new medical products, experts agree that a reliable diagnostic test available at the time of care is the most urgent priority," he said. The idea of the Organization is to create analyzes to guide the development of these tests and to accelerate the process for these products to undergo evaluation by regulatory agencies in a number of countries.
Triiodothyronine (T3) is a hormone that, together with thyroxine (T4), controls how every cell in the body spends energy. This process is called metabolism. When the thyroid produces too much T3 and T4, our metabolism accelerates. When the thyroid produces little T3 and T4, our metabolism slows down.
There is a strong connection between stress and back pain. Stress causes the release of hormones that increase the perception of pain, such as cortisol and adrenocorticotropic (ACTH). Stress hormones also cause muscle tension. Muscles can be so strained to the point of painful muscle spasm. The muscles of the back and neck are particularly sensitive to the effects of stress.
