Virologist Christian Drosten explains on ZDF why Omikron alarms him more than the alpha and delta versions once did. And that he is skeptical of information about mild courses.
ZDF: I know we donât really know much yet. But after everything that has been reported, can this Omikron variant make things even worse?
Christian Drosten: Yes, unfortunately. We donât really know that much about it. I have to say Iâm pretty worried right now. I am surprised to see so many mutations in the virus. These mutations are then the only thing that is really tangible. You donât always understand immediately what mutations do in real life.
There are reports in the media today about mild developments. I donât think thereâs a lot of substance in that yet. We have only detected a little over a thousand cases and their clinical course has to be seen first. That means that you really have to be open to everything. What can already be said is that this infection in South Africa often occurs in young people, in people who first and foremost have already had the disease, who now get it as a second or third infection and then with symptoms.
Nobody can say at the moment what is in store for us. But what you can really say with certainty: Itâs better to be vaccinated. And itâs even better when youâre boosted.
ZDF: Well, it is the case that someone who has previously been considered recovered was already considered to be similar or perhaps even better protected than by the vaccination. If you now say that people in South Africa who have already had Covid become ill , then that speaks for the fact that this protection could in any case be undermined.
Drosten: That is precisely the concern that we have a first real immune escape mutant in front of us right now. The other mutants so far did not have this characteristic as strongly. And of course everyone is a bit nervous and excited to see whether one might lose so much protection, both through surviving the infection and hopefully not through the vaccinations, that one would even have to change the vaccinations again.
All of that will surely answer the next two to three weeks. We must also understand what it is really like now with the severity of the disease. What we cannot say at the moment is how it behaves with us. Because here the virus has different conditions than in South Africa.
Many people have been vaccinated here, they have not recovered. And thatâs a difference.
(âŚ) I also have to say that there have been more and more reports that I have received from my colleagues that there are already quite a few infections in Germany and Europe.
ZDF: That sounds a little different from the first statements from experts. Yesterday, however, they always said that they could still say very little, but I can now feel a slightly different tone in your information.
Drosten: Exactly, so it is actually a situation that is developing from day to day. And right now we donât know what to expect.
But it feels different than the first information about the alpha and delta variants. So I think we should take it seriously now.
If it turns out that the severity of symptoms has been reduced, for example, then we can all be quite relieved. But I am very far from this view at the moment.
ZDF: Will we be able to reliably count on the fact that we will be able to adapt the vaccines again? That is supposed to be the great advantage of this modern technology, that you can catch such mutations again.
Drosten: Yes, that is correct, it will be relatively easy to do technically. And this path is also pre-formed regulatively. But weâre talking about months, of several months, until the first doses are actually delivered. And then really larger numbers have to be produced. So that is not the current problem at all.
We now have to work with the available vaccines, which are really very likely to protect against the severe course. Regardless of whether this variant is now more accessible for portability. We must now see that we are doing two things:
We have to boost it as quickly as possible. Because our real problem is still the delta variant, the winter wave that we have now.
In contrast, the Omikron variant that is now coming from South Africa is a mini-problem at the moment. And we have to close the vaccination gaps. Necessarily. That is very important, because if you are not protected at all, you do not want to hit the Omikron variant.
