Reaction from vaccination<br><br> <br>Children who have been vaccinated may have fever and agitation, some may experience pain, swelling, redness and heat at the vaccination site. Symptoms usually begin about 3-4 hours after injection and last up to 2 days.<br> Vaccination must be injected deep into the muscles, because if the injection is too shallow, it can become a solid lump and sterile abscess.<br> Over-close tetanus vaccination causes arthus reaction, a very specific redness reaction.
