Flu vaccine yes or no? This is a question that is increasingly asked to sports doctors. Dr. Claudio Pecci is extremely supportive of preventive vaccination, which is fundamental for elderly people or those with known pathologies and is recommended for both professional and amateur athletes. «Repeated and continuous physical activity determines an important involvement of the immune system. When we train our defenses fall so it is easier to contract a viral inflammation. To anyone who plans to support a winter program, I suggest to protect yourself with a good vaccination, whether you are training in the open air or in a closed environment» explains the Mapei Sport Research Center director in the last episode of Cubetti di Sapere.
