Objective 　To evaluate on immunogenicity and safety of measles-mumps-rubella-varicella vaccine.
Methods 　The PubMed, BIOSIS Previews, CDSR, The Cochrane Library, CBM, CNKI and VIP were searched between Jan. 1990 and April 2010. Studies were included in the review if they were randomized controlled trials (RCTs) about measles (M) – mumps (M) – rubella (R) and varicella (V) vaccine. Trial screening, data exaction and quality assessment of the included trials were conducted by the method recommended by Cochrane Collaboration. Statistical analyses were conducted by using RevMan 4.2.10 software.
Results 　Five RCTs were included. Among those there were 2 trials of B degree and 3 trials of C degree. Meta-analyses showed that to different inoculation methods, (MMRV or MMR+V) the rate of pain was not significantly different with RR 0.94 and 95%CI 0.83 to 1.05 (P=0.28). The rate of redness was not significantly different with RR 1.08 and 95%CI 0.90 to 1.29 (P=0.40). The rate of hardening was not significantly different with RR 1.16 and 95%CI 0.95 to 1.43 (P=0.14). The rate of fever was significantly different with RR 1.20 and 95%CI 1.12 to 1.29 (P lt;0.000 01). The rate of skin rash was not significantly different with RR 1.18 and 95%CI 1.00 to 1.41 (P=0.05). The serum measles antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.68). The serum mumps antibody positive rate was not significantly different with RR 0.99 and 95%CI 0.50 to 1.01 (P=0.11). The serum rubella antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.68). The se-rum varicella antibody positive rate was not significantly different with RR 1.00 and 95%CI 0.99 to 1.01 (P=0.58).
Conclusion 　Compared with MMR+V vaccine, the MMRV vaccine has the same immune effect. In respect of immune safety, in addition to higher rate of fever after vaccination, other local or systemic reaction is good. For the role of reducing vaccination times and good performance on immune effect and safety, the MMRV vaccine can be regarded as candidate vaccine for children. The fever caused by the new component should be strengthened in the following study. Limited to the quality and account for the current original documents, citing evidence of this systematic review would be cautious. Future studies would expand the sample size, fulfill the test design, increase indicators to improve the quality of research and demonstration intensity.
