MMR and Varicella Vaccine (MMRV)

My daughter had been vaccinated with MMRV last week.  During her childhood, she has no MMR and varicella that’s why we use the catch up schedule to have her complete immunization.  Her second booster will be after 2 or 3 months. I feel nervous of the side effects of MMR and Varicella vaccine but I want also to have protection against these diseases including mumps, measles, rubella and chicken pox. I read some articles that MMR is linked to autism but according to nhs.uk news there is no evidence between MMR and autism.

According to Wikipedia, MMRV vaccine combines the attenuated virus MMR (measles, mumps, rubella) vaccine with the addition of chickenpox vaccine or varicella vaccine (V stands for varicella).  The MMRV vaccine is typically given to children between 1 and 2 years of age.  The second injection or the booster will be given at the age of 4 to 6 years of age.

MMR is a combined vaccine that protects against measles, mumps and rubella.  It is given as a single injection into the muscle of the thigh or upper arm.  The first vaccine for MMR is usually given at 13 months old.

Varicella (chickenpox) vaccine provides protection against the varicella zoster that causes the chickenpox.  Varicella vaccine given to 12 to 15 months old while the second injection will be 4 to 6 years old.
