Research Confirms Need for Vaccine Boosters

Published onsdag 6 september 2006 kl 11.48

Swedish researchers report that vaccine protection for infants against whooping cough appears to wear off after a few years.

Writing in the journal “Pediatrics” doctors at the Swedish Institute for Infectious Disease Control assessed the long-term effects of what are known as pertussis vaccines given at 3, 5, and 12 months of age. The study included 90 percent of Swedish children born in 1996 or later.

They say their observations confirm the need for booster doses of the vaccine when children enter school.
