And for "approved" vaccines that might kill people, there's the Big Pharma Protection Law aka as:
National Childhood Vaccine Injury Act
https://en.wikipedia.org/wiki/National_Childhood_Vaccine_Injury_Act
The National Childhood Vaccine Injury Act (NCVIA) of 1986 (42 U.S.C. §§ 300aa-1 to 300aa-34) was signed into law by United States President Ronald Reagan as part of a larger health bill on November 14, 1986. NCVIA's purpose was to eliminate the potential financial liability of vaccine manufacturers due to vaccine injury claims[1] to ensure a stable market supply of vaccines, and to provide cost-effective arbitration for vaccine injury claims.[2] Under the NCVIA, the National Vaccine Injury Compensation Program (NVICP) was created to provide a federal no-fault system for compensating vaccine-related injuries or death by establishing a claim procedure involving the United States Court of Federal Claims and special masters.[1][3]

Big Pharma can't be sued for vaccine deaths in the regular court system, claims must be "submitted".
