I am not an anti-vaxxer by no means, I got the flu and shingles vaccines earlier this year. This is the first Mrna vaccine to ever be tried and no one knows what kind of long term effects it will have.
Actually, it isn't the first mRNA vaccine. But the non-mRNA Oxford vaccine should be available soon-ish if you are worried.
The covid vaccine is the first mRNA vaccine approved for use in humans (some other mRNA vaccines have been tried in small clinical studies). It will be the first mRNA vaccine to receive widespread human use.
Both the mRNA and Oxford vaccines have been seriously fast tracked and have had reduced safety testing (regarding long term complications) in comparison to a normal vaccine because of the covid emergency.
My concerns match these concerns. But it is very much a balancing act for me because my exposure to Covid is fairly low since I am not doing much that puts me in front of people. If the vaccine were available to me right now, I’d wait a few months to see if everything looked ok unless I had to travel or similar acts that bring me into contact with other humans. Right now my contact with people is pretty minimal.
I have recommended that my 84 year old mother get the vaccination as soon as it is offered because the balance is different for her. She is in a vulnerable age group and her boyfriend is diabetic. The balance shifts hard toward them needing the vaccine as soon as possible.
The reality is that the vaccine is not universally available. Instead it is going to be given to people in a phased approach with me very much late in the line. So I will take the vaccine when my time comes up for it.
My concerns are basically that we don’t know what we don’t know with any new vaccine until a year or so passes. But on the other hand Covid is a deadly disease.
My biggest concern about the vaccine right now is that while it may protect me, I’ve heard reports that they don’t know whether it protects the people around me. And protecting people around me who are immune compromised or likely to be injured severely with Covid is my primary reason for vaccination. It is why I get the flu vaccine every single year. I could survive a flu. I’m not sure my husband could.
Also some of the discussion here has modified my stance by adding extra knowledge.
