Can the drug Broncho-Vaxom be repeated after a while?

The drug Broncho-Vaxom should be used in the scheme: 10 days a month for 3 consecutive months. Repetition of vaccination is possible, but the need for such action is decided by the doctor when he considers that the previous intake of the preparation did not bring the expected effects, i.e. a reduction in the frequency or severity of respiratory infections. In the current situation, vaccines such as Broncho-Vaxom are not available in the form of injections. Below I send a link to a group of similar bacterial vaccines: https://www.gdziepolek.pl/substancje/poliwalentna-szczepionka-bakteryjna Currently, there are a lot of products that aim to strengthen immunity. However, it is worth remembering that the basis is to provide adequate amounts of vitamins and minerals, preferably in the form of food, because in this way their absorption is the greatest. An important issue is also to undertake physical activity in the open air, which allows you to maintain the proper state of minerals and provide vitamin D that performs many important functions in the body. You can also support yourself with preparations available in pharmacies, which are presented in the article in the link below: https://www.gdziepolek.pl/artykuly/wzmacnianie-odpornosci
