I wonder if all the naysayers have the same negative outlook on life in general that they do this vaccine.
I doubt it. The vaccine is pretty specific, which doesn't usually translate directly to the general. But some, I suppose.
Specifally heart inflammation. That's a "major issue."
It's a major issue, but only for a really, really small percentage of the population. All vaccines including mumps, measles, all those were given as kids, tetanus, annual flu, come with risks. As with any vaccine you have to weigh the risk/reward.
Adverse heart reactions are a potential side effect of hydroxychloroquine.
And potentially life-threatening ones at that.
As I'm sure you are aware, all medications have side effects, some of them potentially serious or fatal. Hydroxychloroquine alone (short term, meaning 30 days or less) really has almost no heart related side effects, except for those with existing heart rhythm issues or one of a couple of specific cardiopulmonary conditions.
Hydroxychloroquine is prescribed by far the most for rheumatoid arthritis, and is done so frankly without much consideration about preexisting heart conditions, except for the irregular heartbeat people. And it's prescribed long term. But doctors do tend to take their patients off hydroxychloroquine if they go on antibiotics, so as not to induce heart problems.
It seems pretty clear from the few (mostly botched) studies and anecdotal evidence that once you've been hospitalized it's way too late for hydroxychloroquine to be of any benefit. It needs to be taken early, and in large doses for it to be effective.
The hospital in my county started giving hydroxychloroquine to patients that qualified medically (none of those existing heart conditions) and wanted to take it, immediately after a second positive test for covid. Significantly fewer of those people ended up in the hospital. But it's not a controlled study. They did discover pretty early on that hydroxychloroquine administered with azithromycin resulted in a slight increase (but not slight enough, meaning statistically notable, about a
1-2.something percent increase) in angina and heart failure. Two people (out of thousands) died from heart failure that may or may not have been directly attributable to the hydroxychloroquine and azithromycin. Both deaths were people in their late 50s. So they switched from azithromycin to amoxicillin, which it a different type of antibiotic. The incidents of heart problems dropped back down to normal rates.
So I dunno. It's just a risk/reward thing, like everything else. I say if you are comfortable taking the vaccine, you should take it. Same with hydroxychloroquine, if you're early enough in the diagnosis. If you're not comfortable taking the vaccine, I say do some more research not at news sites. News sites are full of information from reporters who are trying to interpret for you what scientists have tried to interpret for them. That's no place to get medical advice, especially since scientists quite often, as we have all seen lately, can't even agree on the interpretations.
