Keith Speights: Elizabeth has a question. She asks, are there any updates on the development of the Pfizer (PFE -0.19%) and/or Moderna (MRNA 0.89%) booster shots that are projected to be possibly needed in the near future?
Brian Orelli: Yeah. I think they're in clinical trials, is that right?
Speights: Yes. They're taking a little bit different approach. Pfizer is in clinical studies with literally just a third booster shot of their existing vaccine, and Moderna though, they're testing of variant specific shot.
Orelli: Right and I think Novavax (NVAX -0.95%) is at least developing a variant specific shot although I haven't seen that they are in clinical trials yet.
Speights: Pfizer had talked about also pursuing a variants specific shot but I haven't seen anything yet anyway that led me to believe that they are in clinical testing with that at this point. That's where we are.
I think Moderna CEO said that the company expects to have a booster shot available by the fall, or certainly before the end of the year, and I think you've said by the fall.
Orelli: Yes. I think the thing here is probably they're just going to look at antibody levels. They're not going to try to measure the efficacy based on placebo-controlled clinical trial where they would look for whether you'd get COVID-19, and so that allows them to your smaller trials and also allows them to get the data a lot quicker than having to actually measure efficacy in the development of COVID the disease.
