How are vaccines made quickly? Old vaccines make us immune to a germ by using a small part of it (called the antigen) or a weakened version of the germ 🦠🧹. With advancements in science technologies, 🖥️🦾🔬 scientists can now get the instructions (genetic code/ mRNA) to make #antigens 🧬🔍👀and use those to make our body develop immunity 👾🛡️💪🏾. While the BCG vaccine took 13 years to make in the early 1900s ⏳👶🏽➡️🧑🏽, new processes can develop effective vaccines within months or a matter of weeks ⏲️🎉. As a point of comparison, think about what the first mobile phone could do in 1973 🧱👂🏽, and what smartphones are capable of today 🛰️📲👋🏾
