A lot of people aren't honest about their immune system and will be caught lacking from covid, HARD. American's and specifically non-vaccinated American's can be so delusional sometimes. If it takes a person more than a day or two to recover from the flu and be functional, and 2-3 days from the average cold to be functional, they're going to get hit HARD from covid. The amount of people who are anti-vaccine/ no vaccine, yet have terrible immune systems is a lot even in a blue state like New Jersey. These people literally think that like the FLU, they feel like shyt for a week while talking numerous medicines and than they feel better a few days after that week. Covid doesn't work like that at all, if your body doesn't physically recover within 1-3 days, those effects can last anywhere from 2 weeks to months for certain people, and that's not counting those who had to be hospitalized. Get the vaccine!
I can see the difference with my fam compared to my acquaintances/friends/family. I got covid right after Thanksgiving(so not the Delta variant which is more aggressive) from my 70 year old diabetic father, and had a headache/mild sweats on Wednesday night. Thursday was sweaty and achy with tons of mucus production and a sore throat(still could drive and drop some garbage at the dump, thought it was a sore throat), and by Friday was feeling well with no symptoms. I got tested 10 days after contracting it to confirm I got it since my dad found out his office had some cases. I would of never thought it was covid but the test results don't lie. My father had the same recovery time I did and joked around that he had food poisoning that was worse than covid. After that, I still and went to get vaccinated because it's people like me who unintentionally spread it to people who will end up in much harsher situations.
The amount of family friends who couldn't breathe at night who would be perceived as healthy people is enormous, lung production is about 80% after 2-3 months and were functionally bedridden for at least a week are considerable. Sadly, a few dead 50-60 year old family friends as well, and a few had week long hospital trips.
Even though I was fine and probably didn't need to get the vaccine, I still got the vaccine for others, so I don't unintentionally pass it on to somebody or ruin somebody's life. I know that the likelihood of getting covid again is very low, and it being transmissible from me is even lower than that, but I wanted to make sure that it was even lower with the tools we have. Vaccine's aren't perfect but they're the BEST tool to help right now.
