Extensive reaction to Vaccination.

My baby girl had her easy6  and prevenar vaccination  at 10 weeks. She got severe red rashes on her entire thigh(easy6 site) , small area on her lower abdomen (same side)and small area on her other thigh where prevenar was given. Scanning and Blood tests were done, found that there was only Inflammation which gradually reduced. Doctor decided that it was due to Pertituses component of DPT vaccine in easy6. Now last week, when she was 10 weeks, she was given HIB and Prevener. She got red rashes on Prevener injection site. Today, red rash formed on her low abodomen too, on the same side. Attaching the pics. What could be the cause? Should I discontinue further vaccines as it is spreading to other sites?  Also I heard children having vaccine reactions are prone to Autism. We are very much worried.
