I was really glad to see that there are a lot of special measures that are helping to prevent COVID, but the most effective one for me was ivermectin that I purchased at https://www.ivermectincanada.com which is an online pharmacy store, providing this medicine all over the country and helps with the delivery not only in Canada but in the US as well.
If you are going to support your health with different ways, I suggest to take vitamins. It helps to prevent COVID on the beginning stage and also is an amazing treatment against different problems with your health. But like showed the practice, it is really important to be vaccinated, it helps to prevent different problems with this disease and virus.
