In LA and elsewhere, some parents are having trouble finding the new pediatric COVID shot, especially for those under 5. Not all pediatricians or pharmacies have it, even if vaccines.gov says they do.

Data show that a third dose can help boost kids' immunity. Some experts are skeptical that another shot is needed for younger kids.

Parents of children too young for vaccines are exhausted. As omicron surges, they keep trying to protect their kids. But some feel isolated and even forgotten by those who just want to move on.

COVID-19 cases among children are the highest they’ve been since the start of the pandemic.  

The second time Vanessa Quintero's family caught the virus, probably from her 8-year-old daughter, fewer people got sick. They and their doctors credit the protection of vaccination.

The first vaccine required for school was for smallpox, over 200 years ago. And for decades, all states have required that kids be vaccinated against contagious diseases like polio to attend school.

Kids ages 5 to 11 will soon be able to get Pfizer's low-dose COVID vaccine. CDC director Rochelle Walensky agreed with a unanimous decision of a team of advisers that the benefits outweigh the risks.
