Given that Mika got her vaccines two days again, I would suspect that the vomiting is unrelated to that. If she was to experience a mild reaction to the vaccines, it would happen sooner after the vaccines were given. It could be that she has a GI illness or may have eaten something rotten causing the vomiting and lethargy. I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Good luck!
