Around the globe teams of researchers are working tirelessly on the Exploration of a vaccine against the currently rampant .
Worldwide, numerous studies are underway for the development of different types of Vaccine, all rode different far.
Including mRNA vaccines the company, CureVac of Germany, killed vaccines from China, various Protein-based vaccines, and attenuated live vaccine from India.
Experts on vaccine approval to disagree
The efforts to develop a drug against Covid-19, are large and the messages between the consequences and the successful animal experiments, the prospect of an early breakthrough in the research to grow.
However, the speculative statements, to reporting experts from all over the world, are sometimes very different.
Some look optimistically into the future, while others hold back with your statements more. When can be expected a active ingredient?
Oxford researchers is confident
According to the researchers at the Oxford University, so a vaccine is only a few months on the market, because the development is well advanced. Until the end of may 6000 Volunteers to be vaccinated.
This study is positive, could be in September, millions of doses of the Vaccine ready. A fast-track approval procedure was made possible by the Authorities already.
“The prospects are very good,” explains the Professor of medicine and part of the Oxford research team, John Bell, in an Interview with NBC News.
How fast is the process of overriding step, depends on the data of the previous Experiments with the vaccine. However, it is possible to have already the beginning of June, the evidence for whether the vaccine is effective.
Vaccine in the fall, according to Swiss researchers possible
A similar positive Outlook, Swiss researchers say. The immunologist Martin Bachmann from the University hospital Bern will have developed a suitable vaccine candidate against the Coronavirus.
After successful tests, this could come possibly by the end of this year, the use of the Supervisory authority Swissmedic confirmed.
“The schedule is extremely optimistic, but he is not completely pulled by the hair,” said Swissmedic spokesman Lukas Jaggi, compared to the German press Agency.
“Given the urgency of the Coronavirus pandemic, we speak to the approval process of weeks, not months.”
A decision is if you meet all admission requirements before the end of the year, against October. A first study on humans to start in July, to test the General compatibility.
Experts from Germany and the United States show behavior
The Chairman of the world medical Association’s Frank Ulrich Montgomery, however, to bear in mind that the technology of vaccine production and approval takes at least a year.
“In a favorable case, next year we’ll have a vaccine,” said Montgomery, opposite the Passauer Neue Presse.
And also the Word Health Organizastion (WHO) is, according to the Reuters news Agency, a waiting period of approximately 18 months.
Similar to holding back the U.S. office of the Director of the Institute for infectious diseases, Anthony Fauci in an Interview with the American broadcaster NBC.
Although the authority has given for drugs approval FDA the green light to the first clinical Tests of a potential vaccine, he stressed that “the whole process will take at least one or one and a half years”.
In the first place, should be in addition to the effectiveness, namely the compatibility of the product and the safety of those Vaccinated.
The spring of 2021, according to the RKI realistic
With a similar perspective, the researchers look from the Robert-Koch-Institute (RKI) in the next few months.
“Personally, I think it is realistic that it will be in the spring of 2021,” said President Lothar Wieler in March.
Although you could Shorten bureaucratic certainly some of the clinical test phases must not exceed a certain amount of maturity. “We need to have a profile of a security. Vaccines can have side effects.”
Thus, Wieler responded to the statements of the co-owner of the pharmaceutical company CureVa, Dietmar Hopp. This had spoken to already in the autumn of a vaccine to deploy.
This view of the RKIs, other experts, such as biochemists Prof. Klaus Cichutek from Paul close-Ehrlich-Institut. According to him, the production of doses of the vaccine could take on a large scale a lot of time.
“We need to discretion: and what will be the dosage? What is the ideal Form of the antigen in a vaccine? You must vaccinate or twice?”, he explained in an Interview with ZDF.
“This is not to say that preparation is everything.”
The approval process takes several months
The experts from the German centre for infection research (DZIF), which coordinates the country’s research, are more pessimistic.
Although the researchers could be due to other Work is a good basis for the preparation of a vaccine.
However, the development will take so long that a potential vaccine, “can play in the current outbreak phase, no role any more,” says DZIF President Prof. Stephan Becker in an Interview.
That is a vaccine in the next time, according to the experts is hardly possible.
Because according to the preclinical studies in animals for a long clinical studies and observations have to run to the possible after-effects to exclude.
This will ensure that the vaccine not only with the necessary antibodies are formed, but also no relevant side effects occur.
In the normal case, the approval process takes in the EU alone, at least five to seven months.
Different vaccines are possible
Virologist Christian Drosten with forecasts concerning a vaccine and also shows another Problem with the vaccine production.
Although the developments can be rode just as far as the study of inactivated vaccines, far – until a drug is actually widely on the market will be, could take it yet.
“In countries such as in Germany, it is to be so that there will be a whole range of variation of vaccines, perhaps next year at this time,” said the Virologeim NDR Podcast.
“Maybe the first are even a little earlier than this time next year. I want to make now, no exact date.” Finally, Drosten was not a vaccine researcher, but “only” a virologist.
One of the biggest challenges of vaccine production, however, is the large manufacturing of the medium in the millions, as soon as an approval-compliant vaccine was found.
The greatest hope of Israel?
At the Migal Research Institute in the North of Israel, it could actually go faster. There virologists researching for years in another Form of the Coronavirus, called IBV, which infects poultry.
Within this research, they came across a potential vaccine against Covid-19. “It was pure luck,” says the head of the Department for biotechnology at Migal, Dr. Chen Katz, the Jerusalem Post.
“In preclinical studies In living animals, we were able to determine that the vaccine induces high levels of specific Anti-IBV antibodies”. This can also help with Covid-19.
On this basis, the research team plans to run Experiments with small animals to move and then as soon as possible Tests in humans.
The goal of the Migal Institute it according to their own information, to produce within two months of a vaccine and to achieve this within 90 days of approval by the drugs supervision.
When there actually is a vaccine on the market will be, you will know with security, but only if it is finally so far.
