Exercise helps increase the effectiveness of vaccines

According to health experts, gentle movement or exercise after the injection will help increase the effectiveness of the vaccine.

In a review published on Journal of Brain, Behavior and Immunity In July 2014, scientists discovered that exercising after vaccination can enhance the body’s immune response, thereby helping to improve the effectiveness of the vaccine.

The mechanism of action of vaccines is to introduce pathogens or their parts into the body to stimulate the immune system to produce antibodies and T cells. These are two factors used to recognize and fight against diseases. pathogens when they invade in the future. The effectiveness of the vaccine depends on the number of antibodies and T cells produced. The more antibodies and T cells produced, the stronger the immune response, the better the vaccine’s ability to protect.

According to health experts, exercise can stimulate the immune system to produce more antibodies. This helps to improve immunity in general and the body’s response to vaccines in particular. Not only that, but exercise can also increase blood flow, helping to carry the vaccine from the injection site to many other organs and organs.

In a study by Iowa State University in the US, volunteers were divided into two groups. The first group was asked to jog at a moderate pace for 90 minutes or cycle for 15 minutes after getting their flu shot, while the second group just sat still for 90 minutes. A month later, the two groups were tested for antibody responses. The scientists found that the exercise group had twice as much antibody responses as the inactive group.

In addition, exercise can also reduce side effects from vaccination such as pain or discomfort at the injection site. Experts explain that exercise helps blood flow more easily, thereby reducing inflammation and muscle stiffness.

However, the exercise after vaccination should be suitable for each person’s physical condition. Health experts advise people who have just been vaccinated to limit high-intensity exercise. Instead, the recommended exercises during this phase are exercises of moderate intensity (such as brisk walking, cycling, doubles tennis…) or endurance exercises (such as squats, lunge, push-ups, light weight training…). In particular, people who experience side effects such as fatigue, sluggishness, and weakness after vaccination should not try to exercise, but should rest appropriately.

Also in a study by Iowa State University, USA, when testing on mice, scientists found that rats that run on wheels for 90 minutes have a better resistance response after being vaccinated with influenza vaccine than mice. run 45 minutes or 180 minutes. Therefore, according to experts, the optimal exercise duration should be maintained at 90 minutes.

In general, exercise has many benefits for new vaccinations. However, listen to your body and choose the right exercises to get the maximum effect.
