My friends are all making a point of getting sunshine on their skin daily. That is the best that can be done prophylactically where they cannot get Hydrochloroquine or ivermectin.
I have advised them to see if they can get Quercetin and zinc. The quercetin might be available in the drug stores. They know to avoid if possible the injections. Their internet is not more censored than ours and they get and translate Doctors like Hoff and Kaufmann and Mercola. I pray for them and for the borders to be reopened. I chafe at not being able to go back.
Sunshine, exercise, Quercetin, chelated zinc, Vitamins D3, C etc. I haven’t had a cold in years and I,m 72. And they can stick their modified RNA up their own ass.
