I will be flying overseas later this year and need to take several mandatory COVID tests in the weeks before my flight. If I test positive I can't board the plane. I've been vaccinated 3 times and have never been infected with COVID before. I am not eligible for a 4th dose. I think that about 2 months before my flight I should get infected on purpose to boost my immune system, minimizing the risk that I test positive in the weeks before I fly.
