Vaccine Trial
A vaccine trial is a clinical trial that aims at establishing the safety and efficacy of a vaccine prior to it being licensed. A vaccine candidate drug is first identified through preclinical evaluations that could involve high throughput screening and selecting the proper antigen to invoke an immune response. Some vaccine trials may take months or years to complete, depending on the time required for the subjects to react to the vaccine and develop the required antibodies. Preclinical stage Preclinical development stages are necessary to determine the immunogenicity potential and safety profile for a vaccine candidate. This is also the stage in which the drug candidate may be first tested in laboratory animals prior to moving to the Phase I trials. Vaccines such as the oral polio vaccine have been first tested for adverse effects and immunogenicity in monkeys as well as non-human primates and lab mice. Recent scientific advances have helped to use transgenic animals as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms ( dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms ( respiratory failure, shock, or multiorgan dysfunction). Older people are at a higher risk of developing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
