Oh my God, there's nothing worse than when children get sick ? After the vaccination, the temperature hasn't dropped since last night, it was 38.5, now it's already 39. I called an ambulance for the kids, waiting now ? What first aid do they provide? Don't want them to take them to the hospital, or just prescribe treatment and leave? Let our kids not get sick??
