Or it could mean the opposite, Ladybug. Many of the people who have died of Covid were already weakened, either by old age or preexisting conditions, or both. So your heart disease could mean that getting the disease could easily finish you off. The vaccine will not.
Something like 99% of the deaths from Covid have been in unvaccinated individuals. And heart disease of one kind of another is very common in older folks. We all have it, to one extent or another. Yet we've (nearly) all been vaccinated. One conversation I hear a lot around here is, "Which cardiologist do you go to?" I have never heard of any cardiologist, or any other physician, recommend against getting the vaccine because it might kill them due to their physical ailments. (Maybe some people are actually allergic to the vaccine, though I've never met or heard of one.)
To the contrary, every doctor I've gone to in the last few months asked, first thing, "Have you been vaccinated yet?" and when I told them I was one of the first, in Jan.-Feb., they all said, "Good." So, is the entire medical profession in some vast conspiracy to kill off as many humans as possible? That's what some on this forum would have you believe.
Sweep the political propaganda out, clear your brain, and use your common sense to save your own life, or to save yourself from a horrible illness with devastating side effects that can last for months! And this is not an overstatement; it's the simple truth.
