MSNBC Medical Expert: It Is Smart To Study if Booster Shoots Will Be Needed

JACKSON Dr Bhadelia good ░░░░░░░░ Good to have you ░░░░░░░░ BHADELIA Good morning Hallie ░░░░░░░░ So I want to ░░░░░░░░ with that new update ░░░░░░░░ Moderna They are now ░░░░░░░░ some people from its ░░░░░░░░ trial a booster shot ░░░░░░░░ a third shot in ░░░░░░░░ to the two shots ░░░░░░░░ are part of the ░░░░░░░░ And the point is ░░░░░░░░ see whether repeat vaccinations ░░░░░░░░ needed whether they re ░░░░░░░░ or effective This is ░░░░░░░░ interesting What are you ░░░░░░░░ for from this study ░░░░░░░░ what does it mean ░░░░░░░░ Hallie I think this ░░░░░░░░ very smart because there ░░░░░░░░ a couple of things ░░░░░░░░ we know currently You ░░░░░░░░ we know that reinfections ░░░░░░░░ in people who have ░░░░░░░░ natural infections because over ░░░░░░░░ our immunity does tend ░░░░░░░░ start going down In ░░░░░░░░ there was a study ░░░░░░░░ the U K just ░░░░░░░░ week that among health ░░░░░░░░ workers that shows there ░░░░░░░░ a four fold reduction ░░░░░░░░ people who have had ░░░░░░░░ before getting infected again ░░░░░░░░ it does occur What ░░░░░░░░ know is that the ░░░░░░░░ response that a vaccine ░░░░░░░░ you is much stronger ░░░░░░░░ likelihood of getting reinfected ░░░░░░░░ likely much lower and ░░░░░░░░ immune memory may last ░░░░░░░░ longer That s what ░░░░░░░░ think but I think ░░░░░░░░ s smart of Moderna ░░░░░░░░ take this stance to ░░░░░░░░ gathering data on this ░░░░░░░░ it will give us ░░░░░░░░ better the longevity of ░░░░░░░░ how long vaccine will ░░░░░░░░ us is an ongoing ░░░░░░░░ that needs to be ░░░░░░░░ for all the vaccines ░░░░░░░░ they are taking the ░░░░░░░░ to show what those ░░░░░░░░ parameters will look like ░░░░░░░░ other reason it might ░░░░░░░░ just important for us ░░░░░░░░ have this in place ░░░░░░░░ that for most of ░░░░░░░░ who are in this ░░░░░░░░ we think that we ░░░░░░░░ end up needing these ░░░░░░░░ on an annual or ░░░░░░░░ semi annual level because ░░░░░░░░ virus is evolving We ░░░░░░░░ seen these new variants ░░░░░░░░ are more transmissible And ░░░░░░░░ though currently the variants ░░░░░░░░ are out there seem ░░░░░░░░ be the vaccines that ░░░░░░░░ out there can protect ░░░░░░░░ them eventually enough evolution ░░░░░░░░ happen that we may ░░░░░░░░ to adjust that.”
