Determining whether to vaccinate our children against Covid-19 with the existing batch of entirely new vaccines, for which long term side effects are unknown, should be a parent's choice.  Herd immunity for the Covid-19 virus is nonsense since this virus can also be transferred to species other than humans.  I would feel much more comfortable with these vaccines in 5 or 10 years, once the long term side effects, if any, are understood for the new mRNA type of vaccines.  In summary, DO NOT TRY TO MANDATE VACCINATION FOR CHILDREN!!!
