A study published in the journal Vaccine investigated whether the MMR vaccine given to children under two years old after three doses of the DTaP vaccine reduced antibiotic treatments. The study was conducted in Denmark, Finland, Norway, and Sweden and found an 11% overall reduction in antibiotic use with the MMR vaccine. Results varied by country, with Norway showing the highest reduction at 16%. The study suggested that the MMR vaccine provides non-specific protection against non-severe infections, but further research is needed. The findings emphasize the importance of understanding the non-specific effects of MMR vaccines in reducing antibiotic use in children.
