Key result
Gamma-irradiated IPV produced the highest neutralizing antibody titration, significantly increasing humoral and cellular immunity compared to conventional OPV and negative controls (p < 0.05).
Why the study?
Because oral polio vaccine causes OPV-related paralysis, it should be replaced by inactivated polio vaccine.
Does gamma-irradiated inactivated polio vaccine improve humoral and cellular immunity compared to commercial oral polio vaccine in BALB/c mice?
Does gamma-irradiated inactivated polio vaccine improve humoral and cellular immunity compared to commercial oral polio vaccine in BALB/c mice?
p-value: p=<0.05
Gamma-irradiated IPV induces strong humoral and cellular immunity in a mouse model, suggesting it as a potential candidate for polio vaccination.
No takes yet. Share an insight, caveat, or question.
Supports gamma-irradiated IPV development in mice; leaves open translation to human polio vaccination.
Alamuti et al. (2021) studied Polio. Gamma-irradiated inactivated polio vaccine (IPV) plus trehalose vs. Commercial oral polio vaccine (OPV) and negative control was evaluated on Neutralizing antibody titration and splenic lymphocyte proliferation (p=<0.05). Gamma-irradiated IPV produced the highest neutralizing antibody titration, significantly increasing humoral and cellular immunity compared to conventional OPV and negative controls (p < 0.05).
