How long does immunity last And again, four to six months after that last booster is a good time to get the bivalent booster But does your protection fade after a certain amount of time?
One study published in the new england journal of medicine found that this new shot’s protection lasted at least a month (but it likely lasts longer than that, since the study has measured only a month so far) Children as young as 6 months old who were vaccinated with moderna are also eligible for a bivalent booster. Additionally, previous studies of other bivalent covid vaccines showed that immunity lasted about six months.
I know that previous boosters showed waning immunity over time, and i’m. As long as you’ve had your primary series, you can get an updated booster if you are 5 years and older and it’s been at least two months since your last shot
