Question 1

I received the moderna vaccine 8 days ago and  now have hard, red, itchy and warm spot where the injection site is. should a reaction come that late? when should i be concerned?

Accepted Answer

See Moderna COVID 19 vaccine fact sheet at https://www.fda.gov/media/144638/download  *  "Injection site reactions: pain, tenderness & swelling of the lymph nodes in the same arm of the injection, swelling (hardness), & redness". Severe allergic reactions usually occur within an hour or a little longer. I could not find literature about  how long out injection rxn could occur. Look for infection.

Question 2

I'm 42 had a chicken pox vaccine last week. injection site was red and swollen now have like a blister on my chest. is that normal?

Accepted Answer

Vaccine as with any other vaccines can cause redness and slight swelling at the site of shot. The first vaccine will give you 95% protection and close to 100% the second time around. Some people will come down with mild chickenpox after the shot. If not sure, please consult with your physician.

Question 3

Itchy, red, and swollen injection site after vaccinations. should i be worried?

Accepted Answer

This is just a benign side effects of most vaccines , it resolves within few days

Question 4

If i just had the pneumonia vaccine, how do i reduce the redness, swelling, and pain?

Accepted Answer

I'd crack up  a few ice cubes in a dish cloth and put them in a zip lock bag to use as a cool compress. Replace ice  as needed.A couple of ibuprofen tablets up to every 6 hours may also help. It should improve gradually over 2-3 days.

Question 5

Had large local reaction to vaccine. swelling and redness has come down, but there is still a bit of a red area that feels slightly warm. normal?

Accepted Answer

Inject a foreign material into the muscle & it should have a response. Transient swelling & redness is expected, the warmth is dilated capillaries that are part of the reaction. This all usually fades within 48-72 hrs.

Question 6

4 year old with 1 1/2 inch warmth and redness  with pain following  day of  d tap vaccine  (or mmr) is this an emergency

Accepted Answer

likely a local reaction to the DTaP,not the MMR.It's unlikely that it's an infection since it occured within 24 hours. If there is no fever and it's not enlarging, you could give ibuprofen and compresses, but if it's worsening, I would see your doctor, or if they are not available, go to the ER.If you do the local treatment and it isn't better when your doctor opens next, I would call and be seen.

Question 7

Had a large local reaction to vaccine i had 5 days ago. swelling and redness gone down but i still have a slightly warm red area. scared of cellulitis?

Accepted Answer

reaction is dissipating. Insure that the area does not become redder, larger, more tender or have purulent drainage.

Question 8

Had a local reaction to a vaccine two weeks ago. all the swelling and redness went away, but now my skin is discolored like a fading darker bruise?

Accepted Answer

Sometimes bruising can be worse than others. As long as you feel well and it is trending toward improving, I would not worry about it. Good luck.

Question 9

I received a meningitis vaccine monday my arm that the shot was given still  is  a little swollen, patch of redness, and very warm today is it normal?

Accepted Answer

Sometime you can have a local reaction to a shot.No harm done. Reduce the swelling with cold compresses for20 minutes 3-4 a day.

Question 10

My 4 year old has very bright redness under his eyes and on his cheeks.  he had his tdap and mmrv vaccines 7 days ago.  are these related?

Accepted Answer

If he was has having a reaction to the Tdap the time frame is off. It usually occurs 4hrs - 48 hrs post dose. For the MMRV vaccine that is a live virus vaccine. So if you're getting a reaction it would be because you're having a viremia 7-9 days post dose. There might be associated symptoms such as little vesicles around injection site, runny nose, fever,etc. if worried see his doc.
