Furthermore, the neutralizing anti-serum titer and splenic lymphocyte proliferation assay show humoral and cellular immunity were significantly increased in the irradiated vaccine group as compared with conventional group. (umassmed.edu)
CONCLUSION: According to the results, gamma-irradiated IPV could induce humoral and cellular immunity in vaccinated mouse groups, so the irradiated poliovirus could be recommended as a good candidate vaccine to prevent the transport of poliovirus to the central nervous system and thus protect against paralysis. (umassmed.edu)
Consequently, this version of the vaccine boosts immunity and prevents transmission, making it particularly useful in areas where the wild poliovirus continues to circulate (the IPV protects individuals from the disease but is less effective at averting its spread). (ejinsight.com)
