As of February, 75% of children in the US already had natural immunity from prior infection. It could easily be over 90% of children today, given how ubiquitous Omicron has been since then. The CDC’s own research shows that natural immunity is better than vaccinated immunity and a recent New England Journal of Medicine study from Israel has questioned the benefits of vaccinating previously infected persons. Many countries have long credited natural immunity towards vaccine mandates. But not the US.
In this, the leaders of these American health agencies made the US an international outlier in how it treats children. Sweden never offered vaccination to children under 12. Finland limits COVID vaccines to children under 12 who are at high risk. The Norwegian Institute of Public Health has appropriately stated that “some children may benefit” but “previous infection offers as good of protection as the vaccine against reinfection.” Denmark announced on June 22 that its recommendation to vaccinate any children under age 16 was a mistake. “The vaccinations were not predominantly recommended for the child’s sake but to ensure pandemic control,” said Søren Brostrøm, head of the Danish Ministry of Health.
