Yeah and some animals kill humans, does that mean it's okay to kill humans too?

Right now you can consent to get a malaria vaccine, no covert parasite needed.

If the counter that it is for poorer populations, I'd still say you may want to ask them if they want to be injected with a genetically modified parasite. If one single person doesn't want to be in the area, you shouldn't do it. Would you support them dropping these in your neighborhood?

I don't live in malaria country, but yes, absolutely. While we are at it, something just like this for Lyme disease and TBE would be the icing on the cake.

Alright, now go ask all of your neighbors if they want a genetically modified parasite injected into them. If everyone is okay with it, then proceed.

I already have to breathe in pollutants released into my neighbourhood by other people without my consent. I have to deal with the aggregated effects of bad economic decisions made by others. Getting infected with a malaria vaccine instead of actual malaria via a mosquito bite without my consent would be the most benign of this type of problem.

Oh, and this already happens with the attenuated polio vaccine. People can catch the vaccine from those who have been immunised, in a similar way to how they could catch the virus. Delivering the vaccine the same way the pathogen spreads also allows people to opt out by following the same techniques they would to avoid the actual disease. You can use mosquito nets, mosquito sprays, etc., to help avoid both malaria and the mosquito-delivered vaccine.
