New York, Nov 30 - The intake of painkillers at the time of vaccination may reduce the effectiveness of the vaccine, suggests a new study.
When a person is vaccinated, the goal is to produce as many antibodies as possible to effectively neutralise the infection, reported science portal EurekAlert.
To do this, white blood cells - that form a component of the blood and help defend the body against infections spring into action to produce the antibodies.
B cells also serve as the immune system's memory for future protection against the illness.
But Richard P. Phipps and colleagues at University of Rochester discovered that when a person took painkillers, the drug also reduces the ability of B cells to make antibodies.
Their findings were based on laboratory studies of blood samples from people who participated in early clinical trials for the human papillomaviruses - vaccine. HPV is a common cause of various sexually transmitted infections.
