Across the US, Covid-19 cases are rising again, primarily in unvaccinated populations. Most of these cases are due to the highly infectious delta variant of SARS-Cov-2, the coronavirus that causes Covid-19. Many children are among those who aren't vaccinated, simply because no vaccines have been authorized for children under 12. About a quarter of children aged 12-15 years have been vaccinated. Given the rise in cases and the inability to vaccinate young children, many parents are concerned about the safety of traveling this summer.
