To reproduce and survive, viruses invade and take over the DNA or RNA from living cells. Host immune systems fight off the invaders, but viruses develop new tactics and the battle continues. The virus-host struggle is one of the most fascinating in Nature. Virus-based illnesses –smallpox, measles, polio, flu, covid—have been a major force in human history. But modern science has developed effective protective vaccines that have saved millions of lives. Viruses will continue to be a threat, and that keeps experts busy. Dr. Connor explains how viruses invade selected organisms, how immune systems fight against the invaders, and how vaccines provide vital protection against virus diseases.
