For the first time the u s. Food and drug administration fda approved the ebola vaccine rvsv zebov called ervebo on december 19 2019.
In november 2019 the european commission granted a conditional marketing authorization.
Virus ebola vaccine. We developed 2 mrna vaccines based on the ebov envelope glycoprotein which. The vaccine consists of a vesicular stomatitis virus vsv which is an animal virus that causes flulike illness in humans. An investigational vaccine called rvsv zebov which has shown to be safe and protective against the zaire strain of the ebola virus is recommended by the strategic advisory group of experts on immunization sage 1 for use in ebola outbreaks caused by the zaire strain of the virus in the event where there is no licensed vaccine.
During the west africa ebola outbreak at least two vaccines for ebola have been under investigation in clinical trials. Vesicular stomatitis virus vsv can infect humans though this is a self limited infection. Vsv ebov or rvsv zebov sold under the brand name ervebo is a vaccine based on the vesicular stomatitis virus which was genetically modified to express a surface glycoprotein of zaire ebola virus.
The injectable ebola vaccine ervebo is manufactured by merck known as msd outside the us and canada. All of the vaccine. The ebola vaccine licensed by newlink genetics in ames iowa was originally developed by the public health agency of canada which still holds intellectual property rights for it.
One niaid gsk ebola vaccine is a recombinant chimpanzee cold virus used as a vector to deliver segments of genetic material from zaire ebola virus cad3 zebov. This is the first fda approved vaccine for ebola. The vaccine ervebo was developed by merck and protects against ebola virus disease evd caused by zaire ebolavirus in people 18 and older the fda said in a statement.
There is one vaccine that uses a replication defective ebola virus ebov vp30 further treated with hydrogen peroxide to make sure it is unable to replicate. Most current ebola virus ebov vaccine candidates are based on viral vectors some of which cause side effects or require complex manufacturing. The vaccine has been shown to be effective in protecting people from the ebola zaire virus and is recommended by the who strategic advisory group of experts sage for vaccines as part of a broader set of ebola response tools.
Food and drug administration has approved a vaccine for the prevention of ebola the highly contagious virus disease that has killed thousands of people in africa since. There are seven vaccines that utilize a vectored glycoprotein antigen from ebola viruses that has been placed into a virus that will introduce it to the immune system without the ability to cause ebola since there are no ebola replication genes in the glycoprotein which is a protein made by the virus. The vector for this monovalent ebola zaire vaccine is an attenuated vesicular stomatitis virus a virus like rabies virus in the rhabdoviridae family.
Modified mrna vaccines are easily produced safe and are highly immunogenic.
