Objectives: In France it is recommended to administer a booster dose of a pertussis-containing vaccine in adults which can result in them receiving 2 doses of tetanus (T) and/or diphtheria (D/d) and/or poliomyelitis (inactivated, IPV) containing vaccine within a short period (eg catch-up programme or pertussis outbreak). In children and teenagers it has been shown that boosters can be safely given with intervals as short as about 2 years, but in adults there are no data for intervals less than 5 years. We assessed the safety of a booster dose of a pertussis-containing vaccine (acellular component, aP) shortly after a Td-IPV booster.
Methods: 500 healthy adults 1840 years, having received 5 doses of T, D and poliomyelitis vaccine by the age of 18, with the last dose of T and/or D and/or poliomyelitis vaccine given alone or combined at least 5 years previously, were randomised to receive either Td-IPV (REVAXIS®; Group 1) or placebo (Group 2) followed by Td5aP-IPV (REPEVAX®) in both groups one month later in a double-blind trial. Adverse events, including pre-listed events for the first 7 days (injection-site erythema, swelling, and pain, oral temperature 37.5°C, headache and myalgia) were recorded on a diary card.
Results: The groups were similar in terms of age, sex ratio, weight, height, number of previous vaccinations with D, T, and poliomyelitis and intervals between last D, T or poliomyelitis vaccination and study start. 484 subjects who received the second injection were included in the REPEVAX® safety analysis. The adverse event rates reported after REPEVAX® were similar in both groups except for a lower incidence of solicited injection-site reactions in subjects in Group 1.
In Group 1 the rates of injection-site swelling and pain reported within 7 days after REPEVAX® were lower than in Group 2 (19.4% vs 27.7% and 82.6% vs 92.1%, respectively). The confidence interval of the difference between groups did not include 0 (swelling: -8.3 [-15.7; -0.7], pain: -9.5 [-15.5; -3.6]), but this was not judged to be clinically meaningful.
Conclusion: These data support the use of REPEVAX® in adults, even one month after a booster with Td-IPV. REPEVAX® can be used as a booster to reduce the incidence of whooping cough.
