I think it's really important to look at the data rather than speculation. At one point in time every vaccine was new. This type of vaccine may seem "new" but it's been under development world wide for decades. Lots of people have worked on it. Even Mexico was contributing to the technology development as far back as 2016. (The National Autonomous University of Mexico was helping work on it.)
Why don't you look at a bunch of the statistics and research? I think it would be good for you to seek it out and study it independently. Look for research studies, not news reports and definitely not videos and vlogs from people selling books. Just raw data. Things like how many people develop covid symptoms before and after the vaccine. Or what percentage of people have anaphylaxis from the vaccine compared to other common medications like other shots and antibiotics. I think if you're smart it's easy to see what the data says and come to a sound conclusion.
You're correct, children are not at high risk. This isn't uncommon in viruses. Look at chicken pox. It doesn't hurt kids very much, but adults can die from it if they didn't have it as a kid. Unfortunately the vaccine is not yet approved for kids. Because of the ultra-rigorous standards for drug approval in the USA I know that you have to complete the phase 3 human trials and get full FDA approval for giving a medication to adults before you're even allowed to run TESTS on kids. So there's no legal way for drug companies to have prioritized children in the USA. I know it's similar in the UK as well. I don't know if Mexico could have either.
I agree that social distancing and masking go a long way on their own. If people want to continue to isolate and mask I can't really fault them for that - it's fairly effective.
Personally, I'm a hugger. I wanna hug again. XD
It is interesting that you say the UNAM has been working on that, I will look into it. And you do make a point about chickenpox, thank you for pointing it out. I'm not for masks and isolation, I am for hygiene, the reality is I like hugs from family or friend, but in Mexico basically everyone, even people you've just met for the first time expect a hug and a kiss.
I appreciate everyone's opinion on the matter because some have more contact with people in certain fields. I believe that the worst problem now a days is miscommunication or misinformation, and the only way to battle it is to talk and share.
