Were vaccines tested against placebos?
Vaccines are sometimes tested against other vaccines or adjuvants instead of saline placebos to protect participants’ health when an effective vaccine is already available.

Joe Rogan’s skepticism about vaccines, fueled by pandemic-related conspiracy theories, highlights how belief in one conspiracy can lead to acceptance of others, despite overwhelming evidence of vaccine safety and efficacy.
Childhood vaccines are tiny, often just 0.5mL per dose, and claims of 38 vaccines in one shot are false; children receive fewer antigens today than 30 years ago.
A blog claims childhood vaccines have few benefits. In reality, vaccines prevent serious diseases like measles and polio, proving their essential role.
Claims that COVID vaccines contain cancer-causing DNA are false. SV40 promoters are used in manufacturing but are not present in final vaccines.
Claims that vaccines are not placebo tested are false. Many vaccines undergo saline-placebo trials, and the use of active controls is guided by ethical standards.
Claims that polio and measles vaccines don’t work are false. Vaccines have significantly reduced measles cases and nearly eradicated polio, proving their effectiveness.
Claims that COVID vaccines cause cancer via SV40 DNA are false; SV40 promoter genes used in mRNA vaccines do not contain cancer-causing sequences and are removed during production.
Claims that COVID vaccines contain harmful DNA linked to cancer are unfounded; studies show no increased cancer risk, and any detected DNA is due to improper handling and not present in effective doses.
There is no evidence that COVID vaccines cause cancer, and the claim that they contain the SV40 virus is unsupported by scientific evidence.
