There’s a new flu shot on the market this fall, and it’s exciting to those of us in the vaccine world, because initial studies show that it’s actually significantly (27%) more effective than the standard vaccine at preventing flu symptoms entirely. That’s super exciting, since our usual flu vaccines aren’t very good at actually preventing someone from getting the flu (though they are very useful for reducing the risk of hospitalization and death).
But deciding whether you should get the Moderna mRNA vaccine this fall also depends on your tolerance for short-term side effects. If you hate getting your COVID shots because you feel terrible for a day or two, you might prefer to stick to the standard flu shot. The mRNA flu shot causes more arm pain, fatigue, and headaches for one or two days than the standard shot.
It may be a moot point, since flu vaccine availability is still up in the air for this fall because the CDC advisory committee (ACIP) that usually recommends them and makes sure they’re covered by insurance is blocked from meeting due to a court order. We still believe that you’ll be able to get fall vaccines covered with insurance, but whether this newest Moderna mRNA shot is actually available near you is just a guess at this point.
Whether you choose to get the newer shot or not, it’s still exciting stuff. Because this vaccine uses mRNA technology (like the COVID shots), it can be updated much more quickly, and needs far less lead time in the spring to produce a shot that more closely matches whatever flu strain is circulating that year. That’s great news if we have a late-season uptick in a new strain, or if there’s a serious mutation
