What is the difference between DTPa and DTaP?

What is the difference between DTPa and DTaP?

There are three main differences between DTaP and Tdap: DTap is a combination vaccine used to provide immunity against 3 serious diseases (Diphtheria, tetanus, and pertussis) whereas Tdap is used to boost immunity against the same 3 diseases. Tdap contains a lower dose of vaccine than DTaP.

Is DPT vaccine the same as DTP?

DTaP produces fewer side effects and is a safer version of an older vaccine called DTP, which is no longer used in the United States. Tdap vaccine is licensed for people 10 years through 64 years of age. Tdap contains a lower concentration of diphtheria and pertussis toxoids than DTaP. Tdap is given at 11-12 years.

What is the efficacy rate of the Tdap vaccine?

In general, DTaP vaccines are 80% to 90% effective. Among kids who get all 5 doses of DTaP on schedule, effectiveness is very high within the year following the 5th dose – at least 9 out of 10 kids are fully protected.

How effective is DPT vaccine?

In general, DTaP is effective for 8 or 9 in 10 children who get it. Among children who get all 5 shots of DTaP on schedule, effectiveness is very high. The vaccine protects nearly all children (98 in 100) within the year following the last shot.

How often do you need a DPT shot?

Studies estimate that diphtheria toxoid-containing vaccines protect nearly all people (95 in 100) for approximately 10 years. Protection decreases over time, so adults need to get a Td or Tdap booster shot every 10 years to stay protected.

Is Tdap vaccine effective immediately?

Women should be vaccinated during each pregnancy because the mother passes some protection to the baby before he or she is born, and because protection from Tdap is most effective within the first year after receiving the vaccine.

Is DTwP vaccine painful?

Amongst all the recommended vaccines, DTwP is considered most painful as it results into severe pain, fever, vomiting, swelling or redness or inflammation at the site of injection. The reason it is so painful is because the vaccine contains whole cell of pertussis bacteria which is highly immunogenic.
