Why is it difficult to produce vaccines against virus? (Answer in 70-80 words)..
Answers
Answer:
Two centuries isn’t a bad run for a medical technology. But while vaccination has prevented hundreds of millions of deaths since 1796, when Edward Jenner inoculated a boy with cowpox to prevent smallpox, there’s clearly room for improvement: Vaccines are risky or ineffective in people with compromised immune systems, they don’t even exist for several viral diseases, and flu vaccines, in particular, often fail in the elderly.
All of which gave scientists in half a dozen labs the same idea: Rescue one of the oldest biotechnologies with one of the newest
In one study published last month, another posted to the preprint site bioRxiv, and nearly half a dozen that are planned or underway, researchers are using this genome-editing tool to skip a step in antibody production, in the hopes of turning the immune system against viruses for which there are no vaccines.

Answer:
As virus is a very small organism and when it enters in human body it starts multiplying very fast and ruptures the host or immune cells of human body and release its genetic material in that cell and start multiplying inside the cell and the killer cells like macrophages or neutrophils cannot detect the virus that is multiplying inside the cell hence no antibody can be made as the results of it is difficult to produce vaccines against virus
