If I'm allergic to wasp stings, am I allergic to bee stings also?

The first response about dosage of venom, is completely irrelevant. A snake can deliver 1.5ml, Which would be 1,500mg....also has nothing to do with bee venom... Venom means something toxic injected by an animal/insect. Nothing to do with what's in it. So a lot of something you're not allergic to, versus a little of what you are allergic to. There isn't any correlation.

On to your actual answer.
Bees, typically honey bees (allergies to bumblebees are rare) contain hospholipase A2 and mellitin. Waps, which as far as family goes, means hornets, yellow jackets, paper wasps, contain antigen 5. It's very rare that you'd be allergic to both allergens. The one caveat, that is also rare, is that both venoms contain hyaluronidases. If you're allergic to that, then you'd be allergic to both, but allergic reactions to that are usually pretty mild.

After the science, the bottom line answer is, no, just because you're allergic to bees, does not mean you're allergic to wasps. You might be, but it's not because of your bee allergy.

So there's a girl is who said she's allergic to wasps but not bees is that possible

They actually do have the same venom, however it is possible to react to one but not the other. Usually it's based on the amount of venom and how allergic you are, but there can be other factors. Bees, wasps, hornets, and yellow jackets all sting with different amounts of venom.

I am also epipen for wasp stings, but always wondered about honey bee stings... Well, got stung today by a small honey bee in CA and I am not anyphilactic to bees! So, this is possible....

Yep, I'm allergic to a wasp in Houston Texas, and I was stung by a North Carolina wasp not even 30 minutes ago and it's been very mild. Well, mild compared to my other reaction

A few years ago, I was stung by a bee. Thought, no problem, I've been stung before. WRONG. Sever allergic reaction.
Few months after that, I ran into a wasps nest and got stung 12 times. Went to hospital where I was told by doctor that you can be allergic to one without being allergic to the other. I still had a reaction from the twelve stings but not nearly as bad as the one bee sting.
Read it's extremely rare to be allergic to both but I certainly won't take the chance

Some bad info here. First, you can't say that you are likely to react to all types of bees. Wasp and bee venom might be similar but the subtle differences can really change the reaction. It's also false that you cannot react on the first exposure. My understanding is that antibodies are in response to proteins within the venom and those are common, so it isn't that they need to develop after first sting. Here I speak from personal experience. My first bee sting was a wasp and I almost died. Later I was stung by yellow jackets on at least 2 occasions with no problems even though they are in the same family.

Also where you are stung can make a big difference. Being stung in the face or near your neck is worse than say your foot because the swelling in throat risks suffocation where your foot might just swell. The number of bees can make a difference too. You might not be allergic to one but 5 might spark reaction and kill you.

General advice is that severity of reaction gets worse with repeat exposure but I've heard of cases where people also develop immunity. This I think depends on the person. It's also common to hear that reactions get worse with age but that might be an extension of the above logic since usually more exposures go along with age.

If I am having a severe reaction to a wasp sting will a snake bite affect me the same way?

It would be a good idea for you to see an allergist. I'm allergic to All flying insect stings, but to different degrees respectfully. Paper Wasps and Hornets I only need to take antihistamines to stop the reaction. Yellow Jackets are a Whole different story however. That requires an EpiPen and a trip to the ER. I've, luckily, never been stung by a bee tho. After seeing an allergist and having a blood test, he informed me that I'm Highly allergic to bees as well. Even more so, he says, than yellow jackets. Bee Safe and Enjoy the Outdoors!
