Two weeks ago, state Sen. Richard Pan introduced a new bill which would require all children K-12 to be vaccinated against COVID-19 in order to attend school in person after Jan. 1, 2023. Unvaccinated children would be forced into remote learning. Pan said, "We need to make sure schools are safe so that all parents are comfortable sending their children to school." Every parent wants safe schools. But our children deserve medical care driven by facts, not politics. As physician epidemiologists, we have analyzed the data and found that this mandate is not supported by the scientific evidence " which is why no European countries or other U.S. states have implemented their own. California already has a mandate for children over 12, which will be triggered once the vaccines receive full approval. Pan's bill would go much further, requiring every child in K-12 to be vaccinated while the shots are still under emergency use authorization. Excluding unvaccinated children from in-person learning would come at an enormous cost, at a time when they should be catching up on critical academic and social experiences. In December, when the Los Angeles Unified School District tried to implement a K-12 COVID-19 vaccine mandate, they found that 30,000 students ages 12 and older hadn't met the mandate requirements. If we extrapolate those numbers to the entire state, and take into account lower vaccination rates among children ages 5-11, over a million California children could be forced into remote learning.
