The main purpose of this study is to assess the safety and tolerability of a single dose of jnj-64152348, inactivated poliovirus vaccine produced from sabin poliovirus strains on perc6 cells (sipv) in healthy adults, using conventional inactivated poliovirus vaccine produced from salk poliovirus strains (cipv) as reference. There has also been success in eradicating certain strains of the virus of the three types of wild polioviruses (wpvs), the last case of type 2 was reported in 1999 and its eradication was declared in september 2015 the most recent case of type 3 dates to november 2012.
