It's because the vaccine is new — it was approved on the finish of August by the Meals and Drug Administration.
“It’s essential to notice that there are many research which can be measuring” the immunity timeline, he stated ― and plenty of of these research are taking place now.
One research printed within the New England Journal of Drugs discovered that this new shot’s safety lasted a minimum of a month (however it probably lasts longer than that, because the research has measured solely a month to this point). Moreover, earlier research of different bivalent COVID vaccines confirmed that immunity lasted about six months.

When waiting for winter and the vacation season, this booster shot is meant to supply a robust immune response that, hopefully, prevents a spike in infections and protects of us from extreme sickness throughout that point, Abramoff famous.
