repeatedly before the age of five, but no booster dose
was being provided in the country thereafter.
The vaccine is licensed to be given as a four-dose series: three primary doses plus one booster dose
Antibody persistence data through 48 months and response to a single booster dose
at approximately 48 months were evaluated for participants aged 11-18 years in the clinical trial described who also enrolled in an extension study (Pfizer, unpublished data).
An alternative could be to obtain plasma from adult donors who recently received a booster dose
8 at 3rd week and to160 at 3rd week after booster dose
, while the titer after challenge decreased to 47.
However, they noted, "the booster dose
of ZV administered to adults [at least] 70 years old after [at least] 10 years elicited a GMT and geometric mean-fold rise in VZV antibody titer that was noninferior to that of ZV administered as a first dose to subjects [at least] 70 years old.
There is no specific cure for measles except for an MMR vaccination which is administered periodically with booster doses
that can ensure total immunity from the condition.
There was a significant difference in the antibody response of animals who received a booster dose

of vaccine at 6 months only modestly improved on immunogenicity against one of the antigens, clumping factor A.
