I can't believe yall just believe anything these mother fvckers say on twitter:
Evaluation Summary:
- Truth: The claim is false.
- Facts:
- Japan did not raise the general age of all infant vaccinations to two years old. Their routine schedule for many vaccines starts in early infancy.
- SIDS has not disappeared in Japan, although its incidence has decreased, consistent with global trends primarily attributed to safe sleep campaigns.
- A significant change in Japanese vaccination policy occurred in 1994, shifting from mandatory to recommended vaccinations, but this did not involve a blanket postponement of all infant vaccines to age two.
- Science: Extensive scientific research has found no causal link between vaccinations and SIDS. In fact, some evidence suggests vaccines might be protective. The timing of SIDS and routine vaccinations can overlap, but this does not imply causation.
- Recency of Research: The claim itself appears to be a recurring piece of historical misinformation. Contemporary scientific research and current Japanese vaccination policies contradict the claim. While there might have been specific, limited historical instances or proposals regarding vaccine timing changes in Japan, these do not support the broad assertion being made. Ongoing research continues to monitor vaccine safety and SIDS, consistently reaffirming that vaccines are not a cause of SIDS.
Conclusion:
The claim that the incidence of SIDS "disappeared" in Japan after raising the age of vaccination to two years old is
false and not supported by factual evidence or scientific research. Japan's vaccination schedule for infants largely aligns with other developed nations, with many vaccinations starting at two months of age. SIDS, while reduced, has not been eliminated in Japan. The global scientific consensus is that vaccines do not cause SIDS. This claim is a piece of misinformation.
