Statistically, no, they have not. The malaria vaccine is only 75% effective. You can read about it here: https://www.cdc.gov/malaria/malaria_worldwide/reduction/vaccine.html
The small pox vax was 95%.
The MMR vax is 97%. https://www.cdc.gov/measles/vaccination.html
The unvaxxed are spreading it all over, to their families, friends, and neighbors. Every time you come into contact with an infected person, there's a chance you'll be infected too.
When more and more people get vaccinated, fewer and fewer infections happen. Then eventually we push the virus out of existence.
Just like we did with small pox, polio, and almost did with measles.
And, yes, you are wrong. Your refusal to get a vaccination puts everyone around you at risk. You don't live in isolation. Your refusal puts everyone at risk.
No, I am not prepared to admit that children are at a higher risk of serious side effects from the vaccine than they are with the virus itself. I have seen no evidence to suggest that. I have seen that according to the CDC, close to 3K teens developed serious heart & lung complications due to contracting covid. And just over 1K teens developed teh same serious heart & lung complications after receiving the vaccine.
So...kids are more likely to risk death and serious problems without the vaccine.
