Googled the risk from the "P" vaccine.
Encephalopathy leading to permanent neurological damage.
Here's a link.

The risk is very very rare.
From the CDC:
"Mild Problems (Common)
• Fever (up to about 1 child in 4)
• Redness or swelling where the shot was given (up to
about 1 child in 4)
• Soreness or tenderness where the shot was given (up
to about 1 child in 4)
These problems occur more often after the 4th and 5th
doses of the DTaP series than after earlier doses.
Sometimes the 4th or 5th dose of DTaP vaccine is
followed by swelling of the entire arm or leg in which
the shot was given, lasting 1-7 days (up to about 1
child in 30).
Other mild problems include:
• Fussiness (up to about 1 child in 3)
• Tiredness or poor appetite (up to about 1 child in 10)
• Vomiting (up to about 1 child in 50)
These problems generally occur 1-3 days after the shot.
Moderate Problems (Uncommon)
• Seizure (jerking or staring) (about 1 child out of
14,000)
• Non-stop crying, for 3 hours or more (up to about
1 child out of 1,000)
• High fever, over 105oF (about 1 child out of
16,000)
Severe Problems (Very Rare)
• Serious allergic reaction (less than 1 out of a million
doses)
• Several other severe problems have been reported
after DTaP vaccine. These include:
- Long-term seizures, coma, or lowered consciousness
- Permanent brain damage.
These are so rare it is hard to tell if they are caused
by the vaccine.
All vaccines come with risks and so do nearly all medications - I'll take the risks.
