Vaxxines That Do Not Prevent Infection And Allow Virus To Live In Their Host, Allow Mutation Of Stronger Viruses

Vaccines that keep hosts alive but still allow transmission could thus allow very virulent strains to circulate in a population. Also known as viral shedding.

The mRNA vax does not stop infection, it does not stop the infection of others. It allows the virus to live in the host. Lets see what the research conducted in 2015 on this says.

Here we show experimentally that immunization of chickens against Marek’s disease virus enhances the fitness of more virulent strains, making it possible for hyperpathogenic strains to transmit. Immunity elicited by direct vaccination or by maternal vaccination prolongs host survival but does not prevent infection, viral replication or transmission, thus extending the infectious periods of strains otherwise too lethal to persist.

Our data show that anti-disease vaccines that do not prevent transmission can create conditions that promote the emergence of pathogen strains that cause more severe disease in hosts.
