Advantages and disadvantages of different forms of vaccines.

Vaccines type	Advantages	Disadvantages
mRNA vaccines	1. Cellless production; 2. Delivered to DC efficiently	Easy degradation
DNA vaccines	1. Cellless production; 2. The cost is low; 3. Encode any epitope	There is a risk of mutation
Peptide vaccines	1. Cellless production; 2. Easy to transport; 3. Fully degradable	Degradation produces an unrelated immune response
Dendritic cell vaccines	1. The immune stimulation  activity is strong; 2. The clinical effect has  been proved	Cost is high
