A second study from Quebec is calling into question the timing at which young children are vaccinated against measles.
The new research shows that teenagers who received the recommended two doses of measles vaccine but who got the first shot when they were 12 months old were six times more likely to go on to contract the disease than those who got their first dose at 15 months.
Lead author Dr. Gaston De Serres of Quebec's provincial public health agency presented the work Sunday at a major international infectious diseases conference in San Francisco. The study was a followup to an initial paper on the outbreak that he presented to the same conference last year.
