With a simple click of the button, this new delivery system, called ePatch,  that does not need any battery or power to operate can deliver vaccines in a pain-free manner, according to a paper in PNAS .  Conventionally, single-use needles and syringes are used to deliver vaccines. While some people have the fear of needles, there is also the risk of needle-stick injuries to healthcare workers. According to estimates from the Occupational Safety and Health Administration (OSHA), there are up to three million needle-stick injuries that occur globally with about half not being reported. Apart from risks to healthcare workers, needles and syringes are also a huge part of medical waste that is generated every year. The ePatch vaccine delivery system uses microneedles which could reduce the amount of waste generated every year.

As we turn the final pages of the year 2020, COVID-19 vaccines are being given to people in the US and the UK. Undoubtedly, this is the shortest humankind has taken to roll out a vaccine as is evident in the image below.  Science textbooks have reminded us time and again that Edward Jenner created the first vaccine in the world and the work he pioneered in the late 1700s has helped us not only eradicate smallpox but also fight other diseases like polio, yellow fever, chickenpox to name a few. So, here are some fun facts about vaccinations that you likely did not know.  Let’s begin with some controversy.    Edward Jenner did not pioneer vaccination.  People knew well that milkmaids infected with cowpox are immune from smallpox outbreaks.  Jenner was a genius who converted local wisdom into a controlled protocol. He studied if the protocol gave reproducible results.   Like all big discoveries, Jenner’s discovery was no overnight success. He began studying cowpox in the year 1770. He stud
