How to Bring Child's Name to List?

Question

enter image description hereI intend to return the name of the child with the vaccines already administered. what happens is that it does not return anything to me, since if I call the Id it returns the Id of the Child

Model VacinacaoIndexData

      using GestCentros.Models;
using System.Collections.Generic;

namespace GestCentros.ViewModels
{
    public class VacinacaoIndexData
    {
       public IEnumerable<Vacinacao> Vacinacoes { get; set; }
        public IEnumerable<Vacina> Vacinas { get; set; }
        public IEnumerable<Enrollment> Enrollments { get; set; }

    }
}

Controler

public ActionResult Index(int? id, int? Idvacina)
    {
        var user = db.Users.Where(u => u.UserName == User.Identity.Name).FirstOrDefault();

        if (user == null)
        {
            return RedirectToAction("Index", "Home");
        }    
        var viewModel = new VacinacaoIndexData();    
        viewModel.Vacinacoes = db.Vacinacao
            .Include(v => v.Vacinas)
            .Include(v => v.Crianca)
            .Where(c => c.IdCentro == user.IdCentro);  

        if (id != null)
        {
            ViewBag.IdVacinacao = id.Value;
            viewModel.Vacinas = viewModel.Vacinacoes
                .Single(i => i.IdVacinacao == id.Value).Vacinas;
        }    
        if (Idvacina == null) return View(viewModel);           
            ViewBag.IdVacina = Idvacina.Value;
            // Lazy loading
            viewModel.Enrollments = viewModel.Vacinas.Single(x => x.IdVacina == Idvacina).Enrollments;
        // Explicit loading
        Vacina selectedVacina = viewModel.Vacinas.Single(x => x.IdVacina == Idvacina);    
        db.Entry(selectedVacina).Collection(x => x.Enrollments).Load();

            foreach (var enrollment in selectedVacina.Enrollments)
            {
                db.Entry(enrollment).Reference(x => x.Centro).Load();
            }    
            viewModel.Enrollments = selectedVacina.Enrollments;            

        return View(viewModel);
    }

In the Field Name I would like to Show Child Name, but it does not return anything
