Engineering360: "A COVID-19 vaccine primer"

Thanks. I suggest posting additional information regarding their present effectiveness against the known mutations (British Isles, India, Brazil, and others), information to answer some groups' questions about any fetal tissue use history, present studies under way regarding administration of different vaccines to the same individual, etc. Since Engineering 360 has a world-wide audience, you could include more information on where the vaccines are manufactured outside the USA and results of trials on other vaccines, such as the Sputnik-V from Russia or the one from China.

This is a topic that, if well curated or well moderated will be worth reading.
