The first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.
An ongoing clinical protocol at your site includes weekly blood draws to assess an exploratory endpoint. Unfortunately, participants are not happy about visiting the clinic weekly, and they are considering dropping out. Therefore, a protocol amendment is being prepared to remove the weekly blood draw.

What is the FDA?</h3>
The Federal Food and Drugs Act, which was passed in 1906, led to the creation of the Food and Drug Administration (FDA). The organisation is divided into divisions, each of which is in charge of the majority of the organisation's responsibilities relating to food, medicines, cosmetics, animal food, nutritional supplements, medical devices, biological products, and blood products.
The FDA is renowned for its efforts to control the creation of new medications. All new pharmaceuticals must undergo clinical trials, according to regulations set down by the FDA. Before medicines may be offered to humans, pharmaceutical companies must put them through four stages of clinical testing.
