You never hear about infants getting SIDs before their vaccinations. From Steve Kirsch at stevekirsch.substack.com:

The best way to prevent SIDS is to stop vaccinating kids. In every study published in the medical peer-reviewed literature comparing fully vaccinated with fully unvaccinated children in the US, the fully unvaccinated kids were dramatically healthier with far fewer chronic diseases including autism. In 2009, nine House members co-sponsored a bill to require the NIH to do a study that would show this, but the bill never made it out of committee. Congress doesn’t believe that the American public want to know the truth about the childhood vaccines.
Executive summary
Sudden Infant Death Syndrome (SIDS) happens to babies, from 1 month to 1 year in age, but most frequently between 2 and 4 months of age.
Recently I interviewed a former police detective who handled over 250 SIDS cases for a major US city. She revealed her full name and I was able to independently verify her employment at the police department.
In the interview, she revealed that 50% of the SIDS cases happened within 48 hours after a vaccine was given and about 70% of the cases happened within one week of a vaccine.
This can only mean one thing: that the childhood vaccines are the leading cause of SIDS deaths.
There is no other explanation.
Even her pediatrician acknowledged this, but they aren’t allowed to talk about it. She said that the American Academy of Pediatrics trains the pediatricians in how to gaslight parents who seek to blame the vaccine.
This is the first time these statistics have ever been revealed publicly.
All the information is independently verifiable in the police records for any health authority who has any doubts.
Also, I am working with the police department to make these statistics public directly from the police department itself (I cannot compel the production of these records because the FOIA laws in the state exempt these records).
