She should consult with a medical doctor, preferably one familiar with her health and medical situation. Random comments from anonymous strangers likely lacking professional qualifications shouldn't be relied on one way or the other. Good luck and best wishes.

The CDC website provides advice about reactions to Covid shots. It describes allergic reactions, including anaphylactic reactions and hives within 4 hours of the shot as of concern.

It then describes less worrying and common side effects:  "If you had a red, itchy, swollen, or painful rash where you got a COVID-19 shot, you should still get another shot at the recommended interval if a second, additional, or booster shot is recommended. These rashes can start a few days to more than a week after the first shot and are sometimes quite large. These rashes are also known as “COVID arm.” Tell your vaccination provider that you experienced a rash or “COVID arm” after the first shot. Your vaccination provider may recommend that you get the second shot in the opposite arm. If the rash is itchy, you can take an antihistamine. If it is painful, you can take a pain medication like acetaminophen or a non-steroidal anti-inflammatory drug (NSAID)."

My doctor warned the booster has the worst reactions. I'm not rushing out to get it....but I will...I just need to plan my "down" time. I hope she sees her doctor for the rash? Maybe there's a soothing cream...that would give her some relief.

It's not covid arm at this point or I should say it's not obvious rash or red spot around the injection site, just itchy neck, and itchy on her arms. She took benadryl (sp?) for the itching. DD has fever/chills with her 2nd vaccine about nine after her injection. She actually did better with the booster. You could tell she didn't feel well later afternoon the next day, but no fever or chills...ETA she had an achy back too. Heat pad helped with that.

The pharmacist who gave my booster said reaction should be about the same as the first two. And it was. Interesting that there is so much different information going around.

I’m really not impressed by a doctor who puts such negative ideas into patients’ heads. It’s not helpful imo. The information we are given here just says common side effects are the same for all the shots whether 1, 2 or booster. Chances are you’ll not even notice any.

Any relief from antihistamines?

"I’m really not impressed by a doctor who puts such negative ideas into patients’ heads."

^ So agree with this.

"My doctor warned the booster has the worst reactions."

🙄 What's this doctor's source of information? And why would a doctor give such a warning? To discourage people from getting their booster? I've had my booster as have numerous friends and family members. None of us had any reaction. There will always be that one person.

That doctor isn't doing anyone any favors. I had zero reaction to the booster.

I’ve had the booster; so have my adult children, my three sisters, my coworkers, and virtually all my friends. Not one among them had a “worse” reaction, and for the most part it was reported as milder than the first two shots. One friend had a very sore arm.
That is an odd thing for a physician to say…FWIW I’m an RN.

“My doctor warned the booster has the worst reactions.”

Strange that he would say something like that. Of the many people I know who have gotten the booster, the worst reaction has been a sore arm for a day.

No one I know--all people over 70, some 15 people--had anything but mild reactions, myself included.

I had a rash just rush over me in a matter of seconds, since then it's happened four]more times. I still got all the shots as my dr. said and I carry Allegra with me.

I did not get a rash from the vaccines and I get a rash from everything else. But what has been rampant for the past 2 years is contact dermatitis. Either on the body, face or scalp. Naturally I had it on the face and I also suffer from rosacea. I also can't take anti-histamines.

Unbelievable! So, you ONLY want postitive comments or ideas from...YOUR DOCTOR. So, you'd rather YOUR DOCTOR hide useful information from you.

This is a perfect example of what is so scary and frustrating, is there are so many radicals out there willing to hide information and refuse to answer honest to goodness common sense questions from Americans.

eta: changed A to YOUR

I had a severe rash that showed up four or five days after my first Moderna shot, and I took Benadryl, but it did little to help. I did not have the rash on my arm where I got the shot, but on my back, legs, and the tops of my feet. This is a reasonably common side effect to the vaccine, and I did get a second Moderna shot four weeks after the first shot. The severe rash lasted for 10 days to two weeks and then gradually started to go away. It was mostly (but not completely) gone by the time I had the second shot, and then it came back, but not as bad.

I was recommended by my doctor not to get a Moderna booster, and so I got a Pfizer booster. The only reaction I had to this was burning and watery eyes, which I am still experiencing, but it is nothing compared to the rash I got after the Moderna shots. Visine helps with the burning eyes.

Side effects are real - there is no need to deny them - but they are minor compared to the effects of the virus itself.

I was also told by my doctor that the side effects are an indication that the vaccines are working.

I had to take strong pain killers in order to be able to sleep while I had the rashes, and I would wake up when the pain killers wore off.

One thing about the rash - it goes away by itself after a few days (or a couple of weeks), and so it is not a permanent condition, which is very different from effect one can get from the virus itself.

I'm not sure how any medical pro can say which shot might cause the worst reaction(s). It seems to vary so much. We know lots of people who have now had a booster, and not one had anything other than soreness at the injection site. Only two people we know had really uncomfortable reactions to their first shot...one Phizer, one Moderna.

I expect and appreciate science based information from my doctor… and I’d certainly expect that regardless of my nationality.

DD went to the dr.'s yesterday. He didn't think it was booster related since it was the same vaccine she had before which is logical but you never know. . Didn't think it was fungal, prescribed a steroid cream and she can take Claritin during the day and benadryl at night since it makes you sleepy. So we have no idea what caused this reaction.

"This is a perfect example of what is so scary and frustrating, is there are so many radicals out there willing to hide information and refuse to answer honest to goodness common sense questions from Americans." 

It seems to me the true radicals are all the anti science, anti vax , people who  grasp whatever exaggeration, scare story or lie is out there in social media land and take it for gospel instead of actually spending time looking at real numbers and real evidence.  No real information is being hidden, but a lot of false information is being created and circulated to confuse and distress people.  Anti vaxxers aren't interested in the truth. I include in that group quite a few doctors who apparently haven't read a medical journal since they left med school.

As far as the booster being the worst DH and I found the opposite was true. We felt really sick after the 1st and 2nd shots. The booster was no where near as bad for either of us. Sore arm, mild body aches, mild headache and tired for a day.

I’m an RN. Call her doctor. This is NOT the forum

My friend slept for two days. Very different than first shot.

I got the Moderna booster. Upper arm became very red and swollen. When that cleared up, I was left with a rash which has become itchy. I've been scratching it, so have lot of tiny scabs above my elbow. I had a reaction after the second shot and after the booster. Felt crummy, ears and eyes hurt, also had bad chills for 24 hours, and a fever. But I seem ok now. My booster was full strength, hubbies was half. I'm immune compromised, so pharmacist recommended the full strength.

Got my booster on Monday, absolutely no reaction, not even a sore injection site.

Hub and I had our Pfizer boosters yesterday, only mild symptoms today, like a little cold is coming on, but that's already nearly gone, only tender arm left for the most part. Pretty much the same as the initial two shots, just enough to let us know our immune systems reacted. I feel sorry for everyone experiencing stronger reactions, my daughters both had Moderna and have had much more reactions with their initial shots and boosters.
