Wuhan's new coronary virus pneumonia is spreading. Scientists say that they are developing vaccines and are expected to put clinical experiments as soon as possible to prevent infection.But how long does it take to develop vaccines today?
In 2015, the Zika virus broke out in Central South America. Pregnant women infected viruses could cause baby to suffer from small head deformities and cause panic.Scientists decided to develop the vaccine in March 2016. In June 2016, the first vaccine clinical experiment began, but the Zika epidemic has gradually declined and ended.As a result, the vaccine was only stayed in the clinical experiment until 2019, and it was not really used.
Scientists are no stranger to coronary virus
The so -called vaccine is that when the cycle of the disease occurs, it is necessary to vaccinate to prevent the outbreak of the epidemic.When a disease epidemic has disappeared and no longer relapses, the development of vaccine is not important, and the Zika virus vaccine is developed too late.
After the new crown virus broke into the water, a number of pharmaceutical factories and universities immediately announced the development of the vaccine. Is it time to this time?
The new coronary virus is caused by the new coronary virus. The coronary virus is a virus variety that commonly causes respiratory diseases.Including SARS in 2003, and Middle East respiratory syndrome (MERS) that broke out in 2013 and 2015, they were caused by coronary virus, and scientists are no stranger to coronary virus.
The speed that has never been seen before the vaccine development
In this outbreak, pharmaceutical factories were funded by the Popular Psychological Prevention Innovation Alliance (CEPI).Established in 2017, CEPI intentionally set up a fund to assist in the development of vaccine against the spread of epidemic.After China released the genetic diagram of the new coronary virus virus on January 23, CEPI announced the date of allocation of $ 12.5 million to develop a vaccine for $ 12.5 million.
The National Institute of Allergy and Infectious Diseases (Niaid) studied genetic maps in a few days and signed a cooperation agreement with pharmaceutical factories. Pharmaceuticals hoped to study the experience of SARS and MERS from the past to develop vaccines.
Other countries, including China, Germany, Australia, have also announced that they are developing vaccines.Doherty Institute announced on the 29th that the virus was successfully replicated on the 29th to bring samples to the results of the test vaccine.The speed of vaccine development before.
However, the vaccine from R & D to clinical experiments. It takes a period of time approved by government departments and produced in large quantities, for several months, and long years.Whether the epidemic has been controlled at that time, or it is unknown to stop the development due to the outbreak of the epidemic.Scientists hope to develop vaccines that can be widely resisted with coronary virus, which can prevent the possibility of re -eruption of the coronary virus epidemic, including SARS and MERS, and even prevent the raging coronary virus raging in the future.
