Nah, we look at the ingredients of vaccines and then look at the studies on those ingredients and realize that putting heavy metals in the body (to trigger an immune response) is dangerous.
It would be one thing if you could pre-screen your kids to see if they would be safe to get a vaccine, but they don't cover that on most insurance plans.
We also look at the studies on the CDC website that show most vaccines are innefective:

64% of people got the flu in 2019. 48% of vaccinated people got the flu in 2019. Do the math.
