Can a flu shot from 2 years ago provide some protection still?

Question

So I requested the flu shot from my OB and she told me it’s too late in the season. I have to go to a course with 50 people in a crowded little room tomorrow. I had the flu shot 2 years ago and read that past flu shots are not as effective but can still provide some protection to your body. Anyone know if this is true? 😓. 
Wish me luck this weekend 😭

Answer

No, you need a new shot every year.

Answer

Flu shots are still available where I am. Try a Walgreens maybe??

Answer

You can still get the shot, but yeah it is pretty much too late to get one for this season. And it takes 2 weeks to be effective anyway, and can take longer in pregnant women. So its too late for your meeting thing anyway.

Answer

I just got my flu shot on Monday at my first ob appointment

Answer

The flu shot targets the most wide spreading common form of the flu for each season. There are MANY strains each year. So one from 2 years ago likely will have no effects in helping you avoid this year's flu. Flu season ends this month or next month though.

Answer

No flu shot must be administered yearly. There are new strains yearly and they vaccine wears off

Answer

No, it won't help. The one they vaccinated for that year might not even be around this year 🤷🏻‍♀️
Just think of where you place your hands and wash them as often as possible.
