A poll showed that 28% of parents surveyed would "definitely not" vaccinate their children, with just 4% of that group saying a vaccine requirement would change their mind.

The mandate has only been put on 'pause' due to the strong opposition by parents threatening to remove their children from school, but may be revisited in the future.

The vaccine is required for most teachers and child care workers in Washington.

The Washington State Board of Health has voted to not require COVID-19 vaccines for children to attend schools and day cares.

Earlier this year, the technical advisory group, made up of representatives from public health and education sectors statewide, had recommended that the board not require the COVID vaccine for school entry after considering nine criteria, studying the data and collecting input from experts.

That group concluded that the vaccine was safe and effective at preventing disease, and reducing the risk of transmission.
