Final answer:
Recombinant protein vaccines have advantages in terms of cost-effectiveness, safety, and specificity, but they can be complex to produce and may not provide broad strain coverage or stimulate a strong immune response in all individuals.
Step-by-step explanation:
Recombinant protein vaccines have several advantages and disadvantages.
Advantages:
- Cost-effective: Recombinant protein vaccines can be produced in large quantities using a relatively simple and cost-effective process.
- Safety: They do not contain live viruses, reducing the risk of causing disease.
- Specificity: Recombinant protein vaccines can target specific antigens, making them more effective in preventing targeted diseases.
Disadvantages:
- Complex production: Some recombinant protein vaccines require a more complex production process, involving the use of eukaryotic animal hosts.
- Strain coverage: Vaccines targeting specific strains may not provide protection against other strain variants of the same disease.
- Immunogenicity: Recombinant protein vaccines may not stimulate a strong immune response in all individuals.
