The hard lump and redness at your baby’s vaccination site are quite common reactions to vaccines, especially those that contain aluminum as an adjuvant, which is used to enhance immune response. This is generally a mild reaction and may resolve on its own over a few days. The redness and swelling you noticed after applying the ice pack could be due to the cold reaction as well, or it may simply reflect the natural inflammatory response. If your baby doesn’t seem bothered, isn’t running a fever, or showing any signs of a more severe reaction, you can continue applying a cold compress, but do it gently and intermittently—about 15 minutes at a time, allowing breaks in-between to prevent skin damage from the cold. Avoid having the ice pack directly on the skin to avoid frostbite. Use a cloth as a barrier. If the redness or lump increases significantly, it becomes hot, or if your baby displays signs of discomfort or fever, it’s wise to contact your pediatrician to rule out any local infection or unusual reaction. Generally, if there’s no improvement or any new worrying symptoms arise over the next couple of days, it’s a good idea to have a healthcare professional assess the situation just to be sure and provide peace of mind.
