  • The approved mRNA vaccines went through the same approval process as any vaccine. And once approved, they are monitored for safety like any other vaccine. Between pre-approval testing and post-approval monitoring, we would have detected any issues. So the proof is in the pudding — lots of countries have approved them and none have found risks that are worse than the disease they protect against (currently only COVID but there are more mRNA vaccines in the works).

    There's also no reason to fear the way they work. Other vaccines introduce antigens (molecules that your body doesn't like and produces antibodies to attack) in various ways — sometimes with a weakend virus, sometimes with a dead virus, sometimes just the antigens themselves. mRNA is just another way to introduce antigens so your body learns to fight them. For a little while your body follows the instructions in the mRNA to produce the antigens, and then your body learns to attack those antigens. It's not all that different from the way other vaccines work. mRNA breaks down pretty quickly in your body so it's not even in your system for very long, and there's no mechanism in the body for mRNA to produce lasting changes. So it's a lot like you got a cold: for a little while the cold makes your body produce molecules, then your body fights it all off, and then in the end there's no permanent change except your body learned to fight off that particular antigen.

    • Thanks, that's what I thought. They always point to the recorded side effects and I always counter with the fact that the disease is a lot lot worse than the cure, and that it's a classic trolley problem. If the equation is kill one to save a million, you always kill one.

      Or am I missing something?

      • and that it’s a classic trolley problem

        that's not a trolley problem. The trolley problem is an ethics debate about whether it's more ethical to allow multiple people die or take the action of saving that multiple people, condemning another to die instead. Not taking action, however, is itself an action- a choice- that is being made and the problem is entirely disconnected from real life...

        The question of "vaccinate or not vaccinate" is an entirely different question. the question is, should you take an exceedingly small probability of manageable risks (allergic reactions, sore arms) to mitigate a rather high probability lethal risk (long term hospitalization, coma, death. death like symptoms.)

        in the moderna vaccine, There's a 10% chance your arm is going to have swelling/redness/soreness. 1.2% chance that the area effective is large enough to even really notice. and for the more severe risk of alergic reactions, that's 2.5 cases per million doses, and is easily managed simply by maintaining the 15 minute observation after injection. (during which time staff are on hand to deal with the anaphylactic shock, which makes it substantially unlikely to cause permanent harm.)

        the pfizer-biontech vaccine has similar mild reactions, that usually clear up in a single day, and a whopping 11 cases per million doses for allergic reactions (and 80% of those cases happened to people with an already diagnosed hypersensitivity to the PEG.)

        this is compared to the probability of, you know, dying, from being unvaccinated. Per the CDC... yes, the vaccine is highly effective and extremely safe.

      • Also be a little wary of the 'recorded side effects'. In the UK (and I'm sure its not alone), the NHS asked people to record any medical event that happened for a period post-vaccination that could conceivably be a side effect, in an abundance of caution - the idea that they could then sift the data for any actual side effects.

        People often quote this raw data 'look n people had heart attacks after vaccination' - without factoring the expected number of heart attacks if that cohort had not been vaccinated. There's some great stuff in the raw data like people who suffered twisted ankles. Reasonable to record, as say a statistically significant increase in twisted ankles could (say) suggest balance problems were a side effect (they aren't)

      • The trolley problem is a bit different because its result depends on what kind of person you are.

        People who think logically will always pick the option that kills less people. Some people who are emotionally driven hate the idea that manipulating the lever means you are first hand causing the death of said one person, whereas the 5 people, while who could be saved, didnt die outright because of a situation you as the person created.

      • Deaths were not mentioned at all.

  • Your body creates and uses RNA all the time. If there was a problem it would show up nearly instantly. Anything else is something all vaccines do, so we can look to smallpox vaccines which are more than 200 years old for those effects. If there is anything else life itself wouldn't be possible as RNA is critical to how life functions.

  • Unless the friend has training as a microbiologist or something similar their belief is inconsequential. And even then they would be in the vast minority in their field (like a geologist that believes oil doesn't come from the heat and compression of ancient organic matter).

    A lot of people are afraid of new things they don't understand. The hope is that people realize that the fear is irrational and listen to experts in the relevant field.
