Which of the following is a reason RNA vaccine have succeeded where (to date) DNA vaccines have failed in humans?1 pointRNA vaccines can be easily modified to target specific pathogens, while DNA vaccines require a more complex design process.RNA vaccines have a shorter half-life than DNA vaccines, reducing the risk of long-term side effects.RNA vaccines can be delivered directly into the cytoplasm of cells, where they can generate a robust immune response, while DNA vaccines require delivery to the nucleus of cells.RNA vaccines are more stable than DNA vaccines at room temperature, allowing for easier storage and distribution in resource-limited settings.8.

In RNA vaccines, it is necessary for the RNA to replicate to get into the cell.Group of answer choicesTrueFalse

Which of the following is a possible reason that reducing sensing of injected RNA vaccine material by the innate immune system improves their immunogenicity?1 pointReducing innate immune sensing has no effect on vaccine immunogenicity, as the adaptive immune response is primarily responsible for vaccine efficacy.Reducing innate immune sensing allows for increased expression of the vaccine antigen, leading to a stronger immune response to the target pathogenReducing innate immune sensing allows for increased production of pro-inflammatory cytokines, which can enhance the activity of immune cells and improve vaccine efficacy9
