BEACON TRANSCRIPT – Following the 2010 and 2014 whooping cough epidemics, a group of researchers from the Kaiser Permanente Vaccine Study Center has begun to look into the efficiency of new whooping cough vaccine. The new study mirrors Tdap’s long-term inefficiency, proving that teenagers are still at risk of getting sick and spreading the disease.
During a routine check-up of the efficiency of Tdap, a vaccine devised to prevent another whooping cough outbreak, a group of researchers working for the Kaiser Vaccine Study Center discovered that the vaccine provides partial protection against the disease.
Moreover, the same group of researchers found out that the newly-devised variant of the Tdap vaccine, dubbed acellular pertussis vaccine, is even less efficient when it comes to long-term benefits. According to their findings, it would seem that the vaccine’s efficiency drops to below 9 percent in small children and teenagers, after just 4 years.
In order to see how effective the Tdap and its newer versions are, the group of researchers took a closer look at the vaccinations campaigns performed during the 2010 and 2014 outbreaks of whooping cough in the northern part of California.
According to the scientists in charge of this project, it would seem that even with all the campaigns, the health authorities were incapable of containing the disease. The study also shows that in the case of teenagers, the rate of coverage was estimated at around 90 percent. However, the vaccination campaigns and the newly devised Tdap variant were unable to prevent both epidemics. Moreover, it would that the average age of routine vaccination was between 11 and 12 years.
Nicola Klein, the leading author of the study prepared a statement regarding the study findings. According to the doctor, even though the vaccine coverage was high, and the adolescence received regular doses of both Tdap and its newest variant, the rates of infection and spreading continue to increase.
The leading author of the study also added that perhaps the most efficient strategy of preventing another whooping cough outbreak is conducted regular vaccination campaigns among adolescents. Although this is basically common sense, it would seem that this strategy was not very useful in preventing the 2014 epidemic of whooping cough.
Moreover, it would seem that even the vaccine itself has a major flaw when it comes to keeping the disease at bay. The new study mirrors Tdap’s long-term inefficiency. Also, it would seem that the effects of Tdap and its newest variant are quite limited because the vaccine was designed to offer protection on a short-term.
