And what they say they found was that the BA1 part gave a good antibody response against BA1, and also seemed to give a better antibody response against BA5 than the ancestral virus. So what's called bivalent, which means that one part of the vaccine is the ancestral virus, and the other part of the vaccine is the BA1 version of Omicron. So last week, at least at the time we were recording, the Therapeutic Goods Administration gave provisional approval to the Moderna BA1 vaccine. So, is this it, we've finally finished the pandemic, we've solved it? They say they've got vaccines that are effective against Omicron. But good news for you, there's new updated vaccines from both Moderna and Pfizer. Of course we are still getting good protection from disease and of severe disease and dying. Tegan Taylor: And Norman, you are very fond of saying that the current vaccines were designed against the ancestral strain of the coronavirus and they are not as good at protecting us from getting infected with this virus anymore because the variants have moved on. Norman Swan: And I'm physician and journalist Dr Norman Swan, speaking to you from the Gadigal land of the Eora Nation. ![]() ![]() I'm health reporter Tegan Taylor on Jagera and Turrbal land. This is Coronacast, a show all about the coronavirus, and other viral nasties that we have to deal with. Tegan Taylor: Oh well, let's crack on with it. ![]() Norman Swan: That's right, and Will loves it because I go short of oxygen, therefore we keep the timing down. Tegan Taylor: The ostrich approach to everything, yeah, I can get behind that. It's very comfortable under the towel, I can pretend the rest of the world doesn't exist. Norman Swan: Yeah, it took me a while to get the tape recorder going but we're getting there. Tegan Taylor: Norman, I feel like we're going back to our roots today with Coronacast because I can see you on FaceTime and you're under your trusty recording towel.
