I've always used N-95 masks and keep Germ-X hand sanitizer spray in my car. I also take Vitamin D, zinc, along with other boosters. But I have never had the flu nor a flu shot so I trust my immune system to keep me safe.
Better than playing Russian roulette with the jabs.
If you feel so safe, explain how Biden's assistant who was fully jabbed including his booster tested Covid positive??
