Yes, research is ongoing to develop and improve vaccine delivery methods. Some emerging methods include:
- Microneedle Patches: These are small patches with tiny needles that deliver the vaccine painlessly through the skin. They are under investigation for various vaccines, including influenza and COVID-19. - Jet Injectors: These devices use a high-pressure jet to deliver the vaccine through the skin without needles. They offer a needle-free alternative and are being explored for different vaccines. - Edible Vaccines: Research is also being conducted on developing vaccines that can be ingested in the form of genetically modified foods like bananas or potatoes.
