Long term effects are still unknown. Everyone should be able to make their own health decisions. The "vaccine" does not slow the spread so the petitioner's argument that it will protect her daughter is not accurate. It only reduced the impact the virus will have on the recipient. An adult with the vaccine is still more likely to die from the virus than an unvaccinated child. 

Let's be reasonable and actually look at the science.

Offer vaccines for those that want it, allow the at risk to better protect themselves with it. Don't force people, it's their risk to take and only they and their doctor should need to be in the decision.
