Volunteer Protection Act of 1987 - Prescribes circumstances under which volunteers working for nonprofit organizations or government entities shall be immune from personal civil liability.

Requires each State to certify to the Secretary of Health and Human Services before the beginning of each fiscal year (commencing with FY 1989) that it has enacted or has in effect a State law which provides such immunity. Requires the Secretary to reduce by one percent the fiscal year allotment which would otherwise be made to such State to carry out the Social Services Block Grant Program under title XX of the Social Security Act if such law is not in effect.
