Answer 1

Answer:

A COVID‑19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus causing coronavirus disease 2019 (COVID‑19). Prior to the COVID‑19 pandemic, work to develop a vaccine against coronavirus diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) established knowledge about the structure and function of coronaviruses; this knowledge enabled accelerated development of various vaccine technologies during early 2020.[1]
