Hi lybrate-user, DPT specially painful type can cause significant pain and irritability in the bay for next 2-3 days. You can give paracetamol drops (dose as suggested by your paediatrician) to relive this pain. Else you can just do cold sponging, hold or swaddle the baby to reduce the effect of this pain on the baby. IF not better the baby needs to be shown to the paediatrician.
Dear lybrate-user, You can choose either pain or painless DPT vaccine. Both are effective. If you have received the primary dose i.e. At 1.5,2.5 and 3.5 months then this is just a booster. Your primary series is actually determining the effect you get. The boosetrs just prolong that effect for longer duration.
The rabies vaccine effect lasts for 5 years Immunity following a course of doses is typically long lasting. Additional doses are not typically needed except in those at very high risk. Following administration of a booster dose, one study found 97% of immunocompetent individuals demonstrate protective levels of neutralizing antibodies at 10 years.
A booster dose as often as every 6 months to 2 years may be required for person at highest risk for exposure to rabies virus, such as persons who work with rabies virus in research laboratories or vaccine production facilities, veterinarians and staff, and animal control and wildlife officers.
Biovac A is a live attenuated vaccine which is supposed to be equally effective as Havrix 720 which is an inactivated vaccine. Biovac A single dose is enough as per the instructions of manufacturers wheres Havrix needs 2 doses at 6 months interval.
