In The Outcasts of Poker Flat, four troublemakers are banished from Poker Flat. They rest at a cabin overnight and wake up to find that one member of the group has absconded with the horses. The others are found dead at the end of the story. John Oakhurst, a gambler, lives in Poker Flat, a California gold-mining town.
Three hepatitis B vaccine schedules have been shown to induce levels of seroprotection of greater than 95% in infants. One schedule uses an initial dose administered at birth, followed by doses at 1 and 6 months of age. The next schedule has doses given at 2, 4, and 6 months of age. The third schedule is for vaccine given at 6, 10, and 14 weeks of age.
With the advent of combination vaccine, WHO has suggested an additional schedule with monovalent HepB vaccine at birth and DPT-HepB at 6, 10 and 14 weeks. This third option is to make the logistics simpler, which entails a higher cost of the fourth dose (Table II)(7).he principal objective of hepatitis B immunization and its sequelae is to prevent chronic HBV infection and its sequelae. Hepatitis B immunization strategies include a three-pronged attack: (i) routine infant vaccination; (ii) prevention of perinatal HBV transmission; (iii) catch-up vaccination of older age groups.
